infrun.c: stop_stepping -> stop_waiting. stop_stepping is called even when we weren't stepping. It's job really is: static void stop_waiting (struct execution_control_state *ecs) { ... /* Let callers know we don't want to wait for the inferior anymore. */ ecs->wait_some_more = 0; } So rename it for clarity. gdb/ 2014-05-29 Pedro Alves <palves@redhat.com> * infrun.c (stop_stepping): Rename to ...

unbreak infcalls I managed to miss an interaction between the recent *running patch, and target-async, which resulted in infcalls being completely broken on GNU/Linux and remote targets (that is, the async-capable targets). Temporary breakpoint 1, main () at threads.c:35 35 long i = 0; (gdb) p malloc (0) The program being debugged stopped while in a function called from GDB. Evaluation of the expression containing the function (malloc) will be abandoned. When the function is done executing, GDB will silently stop. (gdb) p malloc (0) Program received signal SIGSEGV, Segmentation fault. 0x000000000058d7e8 in get_regcache_aspace (regcache=0x0) at ../../src/gdb/regcache.c:281 281 return regcache->aspace; (top-gdb) The issue is that when running an infcall, the thread is no longer marked as running, so run_inferior_call is not calling wait_for_inferior anymore. Fix this by doing what the comment actually says we do: "Do here what `proceed' itself does in sync mode." And proceed doesn't check whether the target is running. I notice this is broken in case of the early return in proceed, but we were broken before in that case anyway, because run_inferior_call will think the call actually ran. Seems like we should make proceed have a boolean return, and go through all callers making use of it, if necessary. But for now, just fix the regression. Tested on x86_64 Fedora 20. gdb/ 2014-05-29 Pedro Alves <palves@redhat.com> * infcall.c (run_inferior_call): Don't check whether the current thread is running after the proceed call.

thread is running after the proceed call.
enable target async by default; separate MI and target notions of async This finally makes background execution commands possible by default. However, in order to do that, there's one last thing we need to do -- we need to separate the MI and target notions of "async". Unlike the CLI, where the user explicitly requests foreground vs background execution in the execution command itself (c vs c&), MI chose to treat "set target-async" specially -- setting it changes the default behavior of execution commands. So, we can't simply "set target-async" default to on, as that would affect MI frontends. Instead we have to make the setting MI-specific, and teach MI about sync commands on top of an async target. Because the "target" word in "set target-async" ends up as a potential source of confusion, the patch adds a "set mi-async" option, and makes "set target-async" a deprecated alias. Rather than make the targets always async, this patch introduces a new "maint set target-async" option so that the GDB developer can control whether the target is async. This makes it simpler to debug issues arising only in the synchronous mode; important because sync mode seems unlikely to go away. Unlike in previous revisions, "set target-async" does not affect this new maint parameter. The rationale for this is that then one can easily run the test suite in the "maint set target-async off" mode and have tests that enable mi-async fail just like they fail on non-async-capable targets. This emulation is exactly the point of the maint option. I had asked Tom in a previous iteration to split the actual change of the target async default to a separate patch, but it turns out that that is quite awkward in this version of the patch, because with MI async and target async decoupled (unlike in previous versions), if we don't flip the default at the same time, then just "set target-async on" alone never actually manages to do anything. It's best to not have that transitory state in the tree. Given "set target-async on" now only has effect for MI, the patch goes through the testsuite removing it from non-MI tests. MI tests are adjusted to use the new and less confusing "mi-async" spelling. 2014-05-29 Pedro Alves <palves@redhat.com> Tom Tromey <tromey@redhat.com> * NEWS: Mention "maint set target-async", "set mi-async", and that background execution commands are now always available. * target.h (target_async_permitted): Update comment. * target.c (target_async_permitted, target_async_permitted_1): Default to 1.

Make display_gdb_prompt CLI-only. Enabling target-async by default will require implementing sync execution on top of an async target, much like foreground command are implemented on the CLI in async mode. In order to do that, we will need better control of when to print the MI prompt. Currently the interp->display_prompt_p hook is all we have, and MI just always returns false, meaning, make display_gdb_prompt a no-op. We'll need to be able to know to print the MI prompt in some of the conditions that display_gdb_prompt is called from the core, but not all. This is all a litte twisted currently. As we can see, display_gdb_prompt is really CLI specific, so make the console interpreters (console/tui) themselves call it. To be able to do that, and add a few different observers that the interpreters can use to distinguish when or why the the prompt is being printed: #1 - one called whenever a command is cancelled due to an error. #2 - another for when a foreground command just finished. In both cases, CLI wants to print the prompt, while MI doesn't. MI will want to print the prompt in the second case when in a special MI mode. The display_gdb_prompt call in interp_set made me pause. The comment there reads: /* Finally, put up the new prompt to show that we are indeed here. Also, display_gdb_prompt for the console does some readline magic which is needed for the console interpreter, at least... */ But, that looks very much like a no-op to me currently: - the MI interpreter always return false in the prompt hook, meaning actually display no prompt. - the interpreter used at that point is still quiet. And the console/tui interpreters return false in the prompt hook if they're quiet, meaning actually display no prompt. The only remaining possible use would then be the readline magic. But whatever that might have been, it's not reacheable today either, because display_gdb_prompt returns early, before touching readline if the interpreter returns false in the display_prompt_p hook.

PR gdb/13860 - Make MI sync vs async output (closer to) the same. Ignoring expected and desired differences like whether the prompt is output after *stoppped records, GDB MI output is still different in sync and async modes. In sync mode, when a CLI execution command is entered, the "reason" field is missing in the *stopped async record. And in async mode, for some events, like program exits, the corresponding CLI output is missing in the CLI channel. Vis, diff between sync vs async modes: run ^running *running,thread-id="1" (gdb) ... - ~"[Inferior 1 (process 15882) exited normally]\n" =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" si ... (gdb) ~"0x000000000045e033\t29\t memset (&args, 0, sizeof args);\n" - *stopped,frame=...,thread-id="1",stopped-threads="all",core="0" + *stopped,reason="end-stepping-range",frame=...,thread-id="1",stopped-threads="all",core="0" (gdb) In addition, in both cases, when a MI execution command is entered, and a breakpoint triggers, the event is sent to the console too. But some events like program exits have the CLI output missing in the CLI channel: -exec-run ^running *running,thread-id="1" (gdb) ... =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" We'll want to make background commands always possible by default. IOW, make target-async be the default. But, in order to do that, we'll need to emulate MI sync on top of an async target. That means we'll have yet another combination to care for in the testsuite. Rather than making the testsuite cope with all these differences, I thought it better to just fix GDB to always have the complete output, no matter whether it's in sync or async mode. This is all related to interpreter-exec, and the corresponding uiout switching. (Typing a CLI command directly in MI is shorthand for running it through -interpreter-exec console.) In sync mode, when a CLI command is active, normal_stop is called when the current interpreter and uiout are CLI's. So print_XXX_reason prints the stop reason to CLI uiout (only), and we don't show it in MI. In async mode the stop event is processed when we're back in the MI interpreter, so the stop reason is printed directly to the MI uiout. Fix this by making run control event printing roughly independent of whatever is the current interpreter or uiout. That is, move these prints to interpreter observers, that know whether to print or be quiet, and if printing, which uiout to print to. In the case of the console/tui interpreters, only print if the top interpreter. For MI, always print. Breakpoint hits / normal stops are already handled similarly -- MI has a normal_stop observer that prints the event to both MI and the CLI, though that could be cleaned up further in the direction of this patch. This also makes all of: (gdb) foo and (gdb) interpreter-exec MI "-exec-foo" and (gdb) -exec-foo and (gdb) -interpreter-exec console "foo" print as expected.

PR gdb/15713 - errors from i386_linux_resume lead to lock-up linux_nat_resume is not considering that linux_ops->to_resume may throw: /* Mark LWP as not stopped to prevent it from being continued by linux_nat_resume_callback. */ lp->stopped = 0; if (resume_many) iterate_over_lwps (ptid, linux_nat_resume_callback, NULL); If something within linux_nat_resume_callback throws, GDB leaves the lwp_info as if the inferior was resumed, while it actually wasn't.

PR15693 - Fix spurious *running events, thread state, dprintf-style call If one sets a breakpoint with a condition that involves calling a function in the inferior, and then the condition evaluates false, GDB outputs one *running event for each time the program hits the breakpoint. E.g., $ gdb return-false -i=mi (gdb) start ... (gdb) b 14 if return_false () &"b 14 if return_false ()\n" ~"Breakpoint 2 at 0x4004eb: file return-false.c, line 14.\n" ... ^done (gdb) c &"c\n" ~"Continuing.\n" ^running *running,thread-id=(...) (gdb) *running,thread-id=(...) *running,thread-id=(...) *running,thread-id=(...) *running,thread-id=(...) *running,thread-id=(...) ... repeat forever ... An easy way a user can trip on this is with a dprintf with "set dprintf-style call". In that case, a dprintf is just a breakpoint that when hit GDB calls the printf function in the inferior, and then resumes it, just like the case above. If the breakpoint/dprintf is set in a loop, then these spurious events can potentially slow down a frontend much, if it decides to refresh its GUI whenever it sees this event (Eclipse is one such case). When we run an infcall, we pretend we don't actually run the inferior. This is already handled for the usual case of calling a function directly from the CLI: (gdb) p return_false () &"p return_false ()\n" ~"$1 = 0" ~"\n" ^done (gdb) Note no *running, nor *stopped events. That's handled by: static void mi_on_resume (ptid_t ptid) { ... /* Suppress output while calling an inferior function. */ if (tp->control.in_infcall) return; and equivalent code on normal_stop. However, in the cases of the PR, after finishing the infcall there's one more resume, and mi_on_resume doesn't know that it should suppress output then too, somehow. The "running/stopped" state is a high level user/frontend state. Internal stops are invisible to the frontend. If follows from that that we should be setting the thread to running at a higher level where we still know the set of threads the user _intends_ to resume. Currently we mark a thread as running from within target_resume, a low level target operation. As consequence, today, if we resume a multi-threaded program while stopped at a breakpoint, we see this: -exec-continue ^running *running,thread-id="1" (gdb) *running,thread-id="all" The first *running was GDB stepping over the breakpoint, and the second is GDB finally resuming everything. Between those two *running's, threads other than "1" still have their state set to stopped. That's bogus -- in async mode, this opens a tiny window between both resumes where the user might try to run another execution command to threads other than thread 1, and very much confuse GDB. That is, the "step" below should fail the "step", complaining that the thread is running: (gdb) c -a & (gdb) thread 2 (gdb) step IOW, threads that GDB happens to not resume immediately (say, because it needs to step over a breakpoint) shall still be marked as running. Then, if we move marking threads as running to a higher layer, decoupled from target_resume, plus skip marking threads as running when running an infcall, the spurious *running events disappear, because there will be no state transitions at all. I think we might end up adding a new thread state -- THREAD_INFCALL or some such, however since infcalls are always synchronous today, I didn't find a need. There's no way to execute a CLI/MI command directly from the prompt if some thread is running an infcall.

PR gdb/13860: don't lose '-interpreter-exec console EXECUTION_COMMAND''s output in async mode. The other part of PR gdb/13860 is about console execution commands in MI getting their output half lost. E.g., take the finish command, executed on a frontend's GDB console: sync: finish &"finish\n" ~"Run till exit from #0 usleep (useconds=10) at ../sysdeps/unix/sysv/linux/usleep.c:27\n" ^running *running,thread-id="1" (gdb) ~"0x00000000004004d7 in foo () at stepinf.c:6\n" ~"6\t usleep (10);\n" ~"Value returned is $1 = 0\n" *stopped,reason="function-finished",frame={addr="0x00000000004004d7",func="foo",args=[],file="stepinf.c",fullname="/home/pedro/gdb/tests/stepinf.c",line="6"},thread-id="1",stopped-threads="all",core="1" async: finish &"finish\n" ~"Run till exit from #0 usleep (useconds=10) at ../sysdeps/unix/sysv/linux/usleep.c:27\n" ^running *running,thread-id="1" (gdb) *stopped,reason="function-finished",frame={addr="0x00000000004004d7",func="foo",args=[],file="stepinf.c",fullname="/home/pedro/gdb/tests/stepinf.c",line="6"},gdb-result-var="$1",return-value="0",thread-id="1",stopped-threads="all",core="0" Note how all the "Value returned" etc. output is missing in async mode. The same happens with e.g., catchpoints: =breakpoint-modified,bkpt={number="1",type="catchpoint",disp="keep",enabled="y",what="22016",times="1"} ~"\nCatchpoint " ~"1 (forked process 22016), 0x0000003791cbd8a6 in __libc_fork () at ../nptl/sysdeps/unix/sysv/linux/fork.c:131\n" ~"131\t pid = ARCH_FORK ();\n" *stopped,reason="fork",disp="keep",bkptno="1",newpid="22016",frame={addr="0x0000003791cbd8a6",func="__libc_fork",args=[],file="../nptl/sysdeps/unix/sysv/linux/fork.c",fullname="/usr/src/debug/glibc-2.14-394-g8f3b1ff/nptl/sysdeps/unix/sysv/linux/fork.c",line="131"},thread-id="1",stopped-threads="all",core="0" where all those ~ lines are missing in async mode, or just the "step" current line indication: s &"s\n" ^running *running,thread-id="all" (gdb) ~"13\t foo ();\n" *stopped,frame={addr="0x00000000004004ef",func="main",args=[{name="argc",value="1"},{name="argv",value="0x7fffffffdd78"}],file="stepinf.c",fullname="/home/pedro/gdb/tests/stepinf.c",line="13"},thread-id="1",stopped-threads="all",core="3" (gdb) Or in the case of the PRs example, the "Stopped due to shared library event" note: start &"start\n" ~"Temporary breakpoint 1 at 0x400608: file ../../../src/gdb/testsuite/gdb.mi/solib-main.c, line 21.\n" =breakpoint-created,bkpt={number="1",type="breakpoint",disp="del",enabled="y",addr="0x0000000000400608",func="main",file="../../../src/gdb/testsuite/gdb.mi/solib-main.c",fullname="/home/pedro/gdb/mygit/src/gdb/testsuite/gdb.mi/solib-main.c",line="21",times="0",original-location="main"} ~"Starting program: /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.mi/solib-main \n" =thread-group-started,id="i1",pid="21990" =thread-created,id="1",group-id="i1" ^running *running,thread-id="all" (gdb) =library-loaded,id="/lib64/ld-linux-x86-64.so.2",target-name="/lib64/ld-linux-x86-64.so.2",host-name="/lib64/ld-linux-x86-64.so.2",symbols-loaded="0",thread-group="i1" ~"Stopped due to shared library event (no libraries added or removed)\n" *stopped,reason="solib-event",thread-id="1",stopped-threads="all",core="3" (gdb) IMO, if you're typing execution commands in a frontend's console, you expect to see their output. Indeed it's what you get in sync mode. I think async mode should do the same. Deciding what to mirror to the console wrt to breakpoints and random stops gets messy real fast. E.g., say "s" trips on a breakpoint. We'd clearly want to mirror the event to the console in this case. But what about more complicated cases like "s&; thread n; s&", and one of those steps spawning a new thread, and that thread hitting a breakpoint? It's impossible in general to track whether the thread had any relation to the commands that had been executed. So I think we should just simplify and always mirror breakpoints and random events to the console. Notes: - mi->out is the same as gdb_stdout when MI is the current interpreter. I think that referring to that directly is cleaner. An earlier revision of this patch made the changes that are now done in mi_on_normal_stop directly in infrun.c:normal_stop, and so not having an obvious place to put the new uiout by then, and not wanting to abuse CLI's uiout, I made a temporary uiout when necessary. - Hopefuly the rest of the patch is more or less obvious given the comments added.

PR gdb/13860: make -interpreter-exec console "list" behave more like "list". I noticed that "list" behaves differently in CLI vs MI. Particularly: $ ./gdb -nx -q ./testsuite/gdb.mi/mi-cli Reading symbols from /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.mi/mi-cli...done. (gdb) start Temporary breakpoint 1 at 0x40054d: file ../../../src/gdb/testsuite/gdb.mi/basics.c, line 62.

IOW, the program stopped at line 62, and GDB centered the list on that. compare with: $ ./gdb -nx -q ./testsuite/gdb.mi/mi-cli -i=mi =thread-group-added,id="i1" ~"Reading symbols from /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.mi/mi-cli..." ~"done.\n" (gdb) start &"start\n" ... ~"\nTemporary breakpoint " ~"1, main () at ../../../src/gdb/testsuite/gdb.mi/basics.c:62\n" ~"62\t callee1 (2, \"A string argument.\", 3.5);\n" *stopped,reason="breakpoint-hit",disp="del",bkptno="1",frame={addr="0x000000000040054d",func="main",args=[],file="../../../src/gdb/testsuite/gdb.mi/basics.c",fullname="/home/pedro/gdb/mygit/src/gdb/testsuite/gdb.mi/basics.c",line="62"},thread-id="1",stopped-threads="all",core="0" =breakpoint-deleted,id="1" (gdb) -interpreter-exec console list ~"62\t callee1 (2, \"A string argument.\", 3.5);\n" ~"63\t callee1 (2, \"A string argument.\", 3.5);\n" ~"64\t\n" ~"65\t do_nothing (); /* Hello, World! */\n" ~"66\t\n" ~"67\t callme (1);\n" ~"68\t callme (2);\n" ~"69\t\n" ~"70\t return 0;\n" ~"71\t}\n" ^done (gdb) Here the list starts at line 62, where the program was stopped. This happens because print_stack_frame, called from both normal_stop and mi_on_normal_stop, is the function responsible for setting the current sal from the selected frame, overrides the PRINT_WHAT argument, and only after that does it decide whether to center the current sal line or not, based on the overridden value, and it will always decide false. (The print_stack_frame call in mi_on_normal_stop is a little different from the call in normal_stop, in that it is an unconditional SRC_AND_LOC call. A future patch will make those uniform.) A previous version of this patch made MI uniform with CLI here, by making print_stack_frame also center when MI is active. That changed the output of a "list" command in mi-cli.exp, to expect line 57 instead of 62, as per the example above. However, looking deeper, that list in question is the first "list" after the program stops, and right after the stop, before the "list", the test did "set listsize 1". Let's try the same thing with the CLI: (gdb) start 62 callee1 (2, "A string argument.", 3.5); (gdb) set listsize 1 (gdb) list 57 { Huh, that's unexpected. Why the 57? It's because print_stack_frame, called in reaction to the breakpoint stop, expecting the next "list" to show 10 lines (the listsize at the time) around line 62, sets the lines listed range to 57-67 (62 +/- 5). If the user changes the listsize before "list", why would we still show that range? Looks bogus to me. So the fix for this whole issue should be delay trying to center the listing to until actually listing, so that the correct listsize can be taken into account. This makes MI and CLI uniform too, as it deletes the center code from print_stack_frame. A series of tests are added to list.exp to cover this. mi-cli.exp was after all correct all along, but it now gains an additional test that lists lines with listsize 10, to ensure the centering is consistent with CLI's. One related Python test changed related output -- it's a test that prints the line number after stopping for a breakpoint, similar to the new list.exp tests. Previously we'd print the stop line minus 5 (due to the premature centering), now we print the stop line. I think that's a good change.

Allow making GDB not automatically connect to the native target. Sometimes it's useful to be able to disable the automatic connection to the native target. E.g., sometimes GDB disconnects from the extended-remote target I was debugging, without me noticing it, and then I do "run". That starts the program locally, and only after a little head scratch session do I figure out the program is running locally instead of remotely as intended. Same thing with "attach", "info os", etc. With the patch, we now can have this instead: (gdb) set auto-connect-native-target off (gdb) target extended-remote :9999 ... *gdb disconnects* (gdb) run Don't know how to run. Try "help target". To still be able to connect to the native target with auto-connect-native-target set to off, I've made "target native" work instead of erroring out as today. Before: (gdb) target native Use the "run" command to start a native process. After: (gdb) target native Done. Use the "run" command to start a process. (gdb) maint print target-stack The current target stack is: - native (Native process) - exec (Local exec file) - None (None) (gdb) run Starting program: ./a.out ... I've also wanted this for the testsuite, when running against the native-extended-gdbserver.exp board (runs against gdbserver in extended-remote mode). With a non-native-target board, it's always a bug to launch a program with the native target. Turns out we still have one such case this patch catches: (gdb) break main Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138. (gdb) run Don't know how to run. Try "help target". (gdb) FAIL: gdb.base/corefile.exp: run: with core On the patch itself, probably the least obvious bit is the need to go through all targets, and move the unpush_target call to after the generic_mourn_inferior call instead of before. This is what inf-ptrace.c does too, ever since multi-process support was added. The reason inf-ptrace.c does things in that order is that in the current multi-process/single-target model, we shouldn't unpush the target if there are still other live inferiors being debugged. The check for that is "have_inferiors ()" (a misnomer nowadays...), which does: have_inferiors (void) { for (inf = inferior_list; inf; inf = inf->next) if (inf->pid != 0) return 1; It's generic_mourn_inferior that ends up clearing inf->pid, so we need to call it before the have_inferiors check. To make all native targets behave the same WRT to explicit "target native", I've added an inf_child_maybe_unpush_target function that targets call instead of calling unpush_target directly, and as that includes the have_inferiors check, I needed to adjust the targets. Tested on x86_64 Fedora 20, native, and also with the extended-gdbserver board. Confirmed a cross build of djgpp gdb still builds. Smoke tested a cross build of Windows gdb under Wine.

Rename "target child" to "target native". I had been pondering renaming "target child" to something else. "child" is a little lie in case of "attach", and not exactly very clear to users, IMO. By best suggestion is "target native". If I were to explain what "target child" is, I'd just start out with "it's the native target" anyway. I was worrying a little that "native" might be a lie too if some port comes up with a default target that can run but is not really native, but I think that's a very minor issue - we can consider that "native" really means the default built in target that GDB supports, instead of saying that's the target that debugs host native processes, if it turns out necessary. This change doesn't affect users much, because "target child" results in error today: (gdb) target child Use the "run" command to start a child process. Other places "child" is visible: (gdb) help target ... List of target subcommands: target child -- Child process (started by the "run" command) target core -- Use a core file as a target target exec -- Use an executable file as a target ... (gdb) info target Symbols from "/home/pedro/gdb/mygit/build/gdb/gdb". Child process: Using the running image of child Thread 0x7ffff7fc9740 (LWP 4818). While running this, GDB does not access memory from... ... These places will say "native" instead.

Make the dcache (code/stack cache) handle line reading errors better The dcache (code/stack cache) is supposed to be transparent, but it's actually not in one case. dcache tries to read chunks (cache lines) at a time off of the target. This may end up trying to read unaccessible or unavailable memory. Currently the caller gets an xfer error in this case. But if the specific bits of memory the caller actually wanted are available and accessible, then the caller should get the memory it wanted, not an error. gdb/ 2014-05-21 Pedro Alves <palves@redhat.com> * dcache.c (dcache_read_memory_partial): If reading the cache line fails, fallback to reading just the memory the caller wanted. gdb/testsuite/ 2014-05-21 Pedro Alves <palves@redhat.com> * gdb.base/dcache-line-read-error.c: New. * gdb.base/dcache-line-read-error.exp: New.

Make compare-sections work against all targets; add compare-sections [-r] tests. This does two things: 1. Adds a test. Recently compare-sections got a new "-r" switch, but given no test existed for compare-sections, the patch was allowed in with no testsuite addition. This now adds a test for both compare-sections and compare-sections -r. 2. Makes the compare-sections command work against all targets. Currently, compare-sections only works with remote targets, and only those that support the qCRC packet. The patch makes it so that if the target doesn't support accelerating memory verification, then GDB falls back to comparing memory itself. This is of course slower, but it's better than nothing, IMO. While testing against extended-remote GDBserver I noticed that we send the qCRC request to the target if we're connected, but not yet running a program. That can't work of course -- the patch fixes that. This all also goes in the direction of bridging the local/remote parity gap. I didn't decouple 1. from 2., because that would mean that the test would need to handle the case of the target not supporting the command. Tested on x86_64 Fedora 17, native, remote GDBserver, and extended-remote GDBserver. I also hack-disabled qCRC support to make sure the fallback paths in remote.c work. gdb/doc/ 2014-05-20 Pedro Alves <palves@redhat.com> * gdb.texinfo (Memory) <compare-sections>: Generalize comments to not be remote specific.

Fix issue #15778: GDB Aarch64 signal frame unwinder issue The root cause of this issue is unwinder of "#3 <signal handler called>" doesn't supply right values of registers. When GDB want to get the previous frame of "#3 <signal handler called>", it will call cache init function of unwinder "aarch64_linux_sigframe_init". The address or the value of the registers is get from this function. So the bug is inside thie function. I check the asm code of "#3 <signal handler called>": (gdb) frame 3 (gdb) p $pc $1 = (void (*)()) 0x7f931fa4d0 (gdb) disassemble $pc, +10 Dump of assembler code from 0x7f931fa4d0 to 0x7f931fa4da: => 0x0000007f931fa4d0: mov x8, #0x8b // #139 0x0000007f931fa4d4: svc #0x0 0x0000007f931fa4d8: nop This is the syscall sys_rt_sigreturn, Linux kernel function "restore_sigframe" will set the frame: for (i = 0; i < 31; i++) __get_user_error(regs->regs[i], &sf->uc.uc_mcontext.regs[i], err); __get_user_error(regs->sp, &sf->uc.uc_mcontext.sp, err); __get_user_error(regs->pc, &sf->uc.uc_mcontext.pc, err); The struct of uc_mcontext is: struct sigcontext { __u64 fault_address; /* AArch64 registers */ __u64 regs[31]; __u64 sp; __u64 pc; __u64 pstate; /* 4K reserved for FP/SIMD state and future expansion */ __u8 __reserved[4096] __attribute__((__aligned__(16))); }; But in GDB function "aarch64_linux_sigframe_init", the code the get address of registers is: for (i = 0; i < 31; i++) { trad_frame_set_reg_addr (this_cache, AARCH64_X0_REGNUM + i, sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET + i * AARCH64_SIGCONTEXT_REG_SIZE); } trad_frame_set_reg_addr (this_cache, AARCH64_FP_REGNUM, fp); trad_frame_set_reg_addr (this_cache, AARCH64_LR_REGNUM, fp + 8); trad_frame_set_reg_addr (this_cache, AARCH64_PC_REGNUM, fp + 8); The code that get pc and sp is not right, so I change the code according to Linux kernel code: trad_frame_set_reg_addr (this_cache, AARCH64_SP_REGNUM, sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET + 31 * AARCH64_SIGCONTEXT_REG_SIZE); trad_frame_set_reg_addr (this_cache, AARCH64_PC_REGNUM, sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET + 32 * AARCH64_SIGCONTEXT_REG_SIZE); The issue was fixed by this change, and I did the regression test. It also fixed a lot of other XFAIL and FAIL. 2014-05-20 Hui Zhu <hui@codesourcery.com> Yao Qi <yao@codesourcery.com> PR backtrace/16558 * aarch64-linux-tdep.c (aarch64_linux_sigframe_init): Update comments and change address of sp and pc.

fix two latent type errors I'm checking this in as obvious. I was looking at instances of "alloc.*sizeof" and noticed a couple where the types in question are incorrect. In gdbtypes, the code allocates sizeof(int) to represent a struct rank. In mi-cmds, the code uses "struct mi_cmd **" -- one "*" too many. In both cases the problems are latent because in practice the sizes are the same as the sizes of the correct types. Still, it's better to be correct. I think gdb would be improved by a wholesale change from explicit sizeofs to using the libiberty.h allocation macros. In most cases they are both shorter and have better type safety. However, the resulting patch is rather large.

rename "set debugvarobj" to "set debug varobj" I think "set debugvarobj" has the wrong name. It ought to be "set debug varobj", like gdb's other debug settings. This patch makes the change.

Partially available/unavailable data in requested range In gdb.trace/unavailable.exp, an action is defined to collect struct_b.struct_a.array[2] and struct_b.struct_a.array[100], struct StructB { int d, ef; StructA struct_a; int s:1; static StructA static_struct_a; const char *string; }; and the other files are not collected. When GDB examine traceframe collected by the action, "struct_b" is unavailable completely, which is wrong. (gdb) p struct_b $1 = <unavailable> When GDB reads 'struct_b', it will request to read memory at struct_b's address of length LEN. Since struct_b.d is not collected, no 'M' block includes the first part of the desired range, so tfile_xfer_partial returns TARGET_XFER_UNAVAILABLE and GDB thinks the whole requested range is unavailable. In order to fix this problem, in the iteration to 'M' blocks, we record the lowest address of blocks within the request range. If it has, the requested range isn't unavailable completely. This applies to ctf too. With this patch applied, the result looks good and fails in unavailable.exp is fixed. (gdb) p struct_b $1 = {d = <unavailable>, ef = <unavailable>, struct_a = {a = <unavailable>, b = <unavailable>, array = {<unavailable>, <unavailable>, -1431655766, <unavailable> <repeats 97 times>, -1431655766, <unavailable> <repeats 9899 times>}, ptr = <unavailable>, bitfield = <unavailable>}, s = <unavailable>, static static_struct_a = {a = <unavailable>, b = <unavailable>, array = {<unavailable> <repeats 10000 times>}, ptr = <unavailable>, bitfield = <unavailable>}, string = <unavailable>} gdb: 2014-05-05 Yao Qi <yao@codesourcery.com> Pedro Alves <palves@redhat.com> * tracefile-tfile.c (tfile_xfer_partial): Record the lowest address of blocks that intersects the requested range.

Show new created display When I run refactored unavailable.exp, I find command display behaves a little different on live inferior and on examining traceframes. In live inferior, when command "display argc" is typed, the value of "argc" is shown. (gdb) display argc 1: argc = 1 '\001' however, on tfile target, when command "display argc" is typed, the value of "argc" is not shown. (gdb) tfind Found trace frame 0, tracepoint 1 at ../../../../git/gdb/testsuite/gdb.trace/unavailable.cc:198 198 i = (int) argc + argi + argf + argd + argstruct.memberi + argarray[1]; (gdb) display argc I also notice that on "core" target, the value of "argc" isn't shown either. This difference is caused by the code below in printcmd.c:display_command, if (from_tty && target_has_execution) do_one_display (new); Looks the value of each display is shown if the target has execution. Source code archaeology doesn't tell much about this requirement. However, if we type command "display" then on "core" or "tfile" target, the value of "argc" is still displayed, for "core" target, (gdb) display argc (gdb) display 1: argc = 1 '\001' for "tfile" target, (gdb) display argc (gdb) display 1: argc = <unavailable> I feel that it is not necessary to have such "target has execution" requirement to show the value of new created display. Auto-display is a feature to show the value of expression frequently, has nothing to do with whether target has execution or not. On the other hand, GDB has the requirement for new created display, but command "display" can still show them, this is an inconsistency, which should be fixed. This patch is to remove the checking to target_has_execution from the condition. gdb: 2014-05-05 Yao Qi <yao@codesourcery.com> * printcmd.c (display_command): Remove the check to target_has_execution.

Extend recognized types of SDT probe's arguments This commit is actually an update to make the parser in gdb/stap-probe.c be aware of all the possible prefixes that a probe argument can have. According to the section "Argument Format" in: <https://sourceware.org/systemtap/wiki/UserSpaceProbeImplementation> The bitness of the arguments can be 8, 16, 32 or 64 bits, signed or unsigned. Currently GDB recognizes only 32 and 64-bit arguments. This commit extends this. It also provides a testcase, only for x86_64 systems. gdb/ 2014-05-02 Sergio Durigan Junior <sergiodj@redhat.com> * stap-probe.c (enum stap_arg_bitness): New enums to represent 8 and 16-bit signed and unsigned arguments.

Fix PR breakpoints/16889: gdb segfaults when printing ASM SDT arguments This commit fixes PR breakpoints/16889, which is about a bug that triggers when GDB tries to parse probes whose arguments do not contain the initial (and optional) "N@" part. For reference sake, the de facto format is described here: <https://sourceware.org/systemtap/wiki/UserSpaceProbeImplementation> Anyway, this PR actually uncovered two bugs (related) that were happening while parsing the arguments. The first one was that the parser *was* catching *some* arguments that were missing the "N@" part, but it wasn't correctly setting the argument's type. This was causing a NULL pointer being dereferenced, ouch... The second bug uncovered was that the parser was not catching all of the cases for a probe which did not provide the "N@" part. The fix for that was to simplify the check that the code was making to identify non-prefixed probes. The code is simpler and easier to read now. I am also providing a testcase for this bug, only for x86_64 architectures. gdb/ 2014-05-02 Sergio Durigan Junior <sergiodj@redhat.com> PR breakpoints/16889 * stap-probe.c (stap_parse_probe_arguments): Simplify check for non-prefixed probes (i.e., probes whose arguments do not start with "N@").

compare-sections: New -r option. When connecting to a remote system, we use the compare-sections command to verify that the box is running the code that we think it is running. Since the system is up and running and *NOT* 'freshly downloaded without yet executing anything', read-write sections, of course, differ from what they were in the executable file. Comparing read-write sections takes time and more importantly the MIS-MATCHED output is confusing to some users. The compare-sections command compares all loadable sections including read-write sections. This patch gives the user the option to compare just the loadable read-only sections. gdb/ 2014-05-01 David Taylor <dtaylor@emc.com> * remote.c (compare_sections_command): Add -r option to compare all loadable read-only sections. gdb/doc/ 2014-05-01 David Taylor <dtaylor@emc.com> * gdb.texinfo (compare-sections): Document the new -r (read-only) option.

Fix remote connection to targets that don't support the QNonStop packet. ... and others. The recent patch that fixed several "set remote foo-packet on/off" commands introduced a regression, observable when connecting GDB to QEMU. For instance: (gdb) set debug remote 1 (gdb) tar rem :4444 Remote debugging using :4444 Sending packet: $qSupported:multiprocess+;qRelocInsn+#2a...Ack Packet received: PacketSize=1000;qXfer:features:read+ Packet qSupported (supported-packets) is supported Sending packet: $Hgp0.0#ad...Ack Packet received: OK Sending packet: $qXfer:features:read:target.xml:0,ffb#79...Ack Packet received: [...] Sending packet: $qXfer:features:read:arm-core.xml:0,ffb#08...Ack Packet received: [...] !!! -> Sending packet: $QNonStop:0#8c...Ack Packet received: Remote refused setting all-stop mode with: The "QNonStop" feature is associated with the PACKET_QNonStop packet, with a default of PACKET_DISABLE, so GDB should not be sending the packet at all. The patch that introduced the regression decoupled packet_config's 'detect' and 'support' fields, making the former (an auto_boolean) purely the associated "set remote foo-packet" command's variable. In the example above, the packet config's 'supported' field does end up correctly set to PACKET_DISABLE. However, nothing is presently initializing packet configs that don't actually have a command associated. Those configs's 'detect' field then ends up set to AUTO_BOOLEAN_TRUE, simply because that happens to be 0. This forces GDB to assume the packet is supported, irrespective of what the target claims it supports, just like if the user had done "set remote foo-packet on" (this being the associated command, if there was one). Ideally, all packet configs would have a command associated. While that isn't true, make sure all packet configs are initialized, even if no command is associated, and add an assertion that prevents adding more packets/features without an associated command. Tested on x86_64 Fedora 17, against pristine gdbserver, and against a gdbserver with the QNonStop packet/feature disabled with a local hack. gdb/ 2014-04-29 Pedro Alves <palves@redhat.com> * remote.c (struct packet_config) <detect>: Extend comment.

dwarf2read.c::read_subrange_type: Handle dynamic lower bounds Currently, read_subrange_type handles dynamicity only in the case of the upper bound, and assumes that the lower bound is always static. That's rooted in the fact that dynamicity was added to support C99 variable-length arrays, where the lower bound is always zero, and therefore never dynamic. But the lower bound can, in fact, be dynamic in other languages such as Ada. Consider for instance the following declaration in Ada... type Array_Type is array (L .. U) of Natural; ... where L and U are parameters of the function where the declaration above was made, and whose value are 5 and 10. Currently, the debugger is able to print the value of the upper bound correctly, but not the lower bound: (gdb) ptype array_type type = array (1 .. 10) of natural After this patch, the debugger now prints: (gdb) ptype array_type type = array (5 .. 10) of natural gdb/ChangeLog: * dwarf2read.c (read_subrange_type): Handle dynamic DW_AT_lower_bound attributes.

Improve Ada dynamic range type handling. Consider the following declaration in Ada... type Array_Type is array (L .. U) of Natural; ... where L and U are parameters of the function where the declaration above was made. At the moment, GDB relies on descriptive types in order to properly decode the array bounds. For instance, if L was 5, and U was 10, we would see the following: (gdb) ptype array_type type = array (5 .. 10) of natural (gdb) maintenance set ada ignore-descriptive-types (gdb) ptype array_type type = array (1 .. 28544912) of natural This patch enhances ada_discrete_type_{high,low}_bound to resolve any dynamicity. This is sufficient to fix the case of the upper bound.

Enhance dwarfread.c::resolve_dynamic_type to resolve dynamic ranges This change breaks down the resolve_dynamic_bounds function which works only on arrays and its index range types into two functions, one that resolves range types, and one that resolves arrays (using the new routine to resolve the array's index range type). The is_dynamic_type and resolve_dynamic_type function are then re-organized to handle range types as well. One small change worth mentioning is the fact that, now that range types are resolved on their own (rather than in the limited context of array index types), the resolved range types are created from a copy of the dynamic range type, rather than from scratch (first parameter of create_range_type). This allows us to preserve as many original properties in the resolved type as possible (Eg. the type's name). This is preparation work that will help better support dynamic range types for languages that allow the declaration of such types (Eg. Ada). gdb/ChangeLog: * dwarf2read.c (is_dynamic_type): Return true for dynamic range types. Adjust the array handling implementation to take advantage of this change.

PR server/16255: gdbserver cannot attach to a second inferior that is multi-threaded. On Linux, we need to explicitly ptrace attach to all lwps of a process. Because GDB might not be connected yet when an attach is requested, and thus it may not be possible to activate thread_db, as that requires access to symbols (IOW, gdbserver --attach), a while ago we make linux_attach loop over the lwps as listed by /proc/PID/task to find the lwps to attach to. linux_attach_lwp_1 has: ... if (initial) /* If lwp is the tgid, we handle adding existing threads later. Otherwise we just add lwp without bothering about any other threads. */ ptid = ptid_build (lwpid, lwpid, 0); else { /* Note that extracting the pid from the current inferior is safe, since we're always called in the context of the same process as this new thread. */ int pid = pid_of (current_inferior); ptid = ptid_build (pid, lwpid, 0); } That "safe" comment referred to linux_attach_lwp being called by thread-db.c. But this was clearly missed when a new call to linux_attach_lwp_1 was added to linux_attach. As a result, current_inferior will be set to some random process, and non-initial lwps of the second inferior get assigned the pid of the wrong inferior. E.g., in the case of attaching to two inferiors, for the second inferior (and so on), non-initial lwps of the second inferior get assigned the pid of the first inferior. This doesn't trigger on the first inferior, when current_inferior is NULL, add_thread switches the current inferior to the newly added thread. Rather than making linux_attach switch current_inferior temporarily (thus avoiding further reliance on global state), or making linux_attach_lwp_1 get the tgid from /proc, which add extra syscalls, and will be wrong in case of the user having originally attached directly to a non-tgid lwp, and then that lwp spawning new clones (the ptid.pid field of further new clones should be the same as the original lwp's pid, which is not the tgid), we note that callers of linux_attach_lwp/linux_attach_lwp_1 always have the right pid handy already, so they can pass it down along with the lwpid. The only other reason for the "initial" parameter is to error out instead of warn in case of attach failure, when we're first attaching to a process. There are only three callers of linux_attach_lwp/linux_attach_lwp_1, and each wants to print a different warn/error string, so we can just move the error/warn out of linux_attach_lwp_1 to the callers, thus getting rid of the "initial" parameter. There really nothing gdbserver-specific about attaching to two threaded processes, so this adds a new test under gdb.multi/. The test passes cleanly against the native GNU/Linux target, but fails/triggers the bug against GDBserver (before the patch), with the native-extended-remote board (as plain remote doesn't support multi-process). Tested on x86_64 Fedora 17, with the native-extended-gdbserver board. gdb/gdbserver/ 2014-04-25 Pedro Alves <palves@redhat.com> PR server/16255 * linux-low.c (linux_attach_fail_reason_string): New function.

Fix several "set remote foo-packet on/off" commands. For several RSP packets, there's a corresponding "set remote foo-packet on/off/auto" command that one can use do bypass auto-detection of support for the packet or feature. However, I noticed that setting several of these commands to 'on' or 'off' doesn't actually have any effect. These are, at least: set remote breakpoint-commands-packet set remote conditional-breakpoints-packet set remote fast-tracepoints-packet set remote static-tracepoints-packet set remote install-in-trace-packet These are commands that control a remote protocol feature that doesn't have a corresponding regular packet, and because of that we cache the knowledge of the remote side support as returned by the qSupported packet in the remote_state object. E.g., in the case of the 'set remote breakpoint-commands-packet' command, whether the feature is supported is recorded in the 'breakpoint_commands' field of the remote_state object. Whether to bypass packet support auto-detection or not is controlled by the 'detect' field of the corresponding packet's packet_config structure. That field is the variable associated directly with the "set remote foo-packet" command. Actual remote stub support for the packet (or feature) is recorded in the 'support' field of the same structure. However, when the user toggles the command, the 'support' field is also correspondingly updated to PACKET_ENABLE/DISABLE/SUPPORT_UNKNOWN, discarding the knowledge of whether the target actually supports the feature. If one toggles back to 'auto', it's no big issue for real packets, as they'll just end up re-probed the next time they might be necessary. But features whose support is only reported through qSupported don't get their corresponding (manually added/maintained) fields in remote_state objected updated. As we lost the actual status of the target support for the feature, GDB would need to probe the qSupported features again, which GDB doesn't do. But we can avoid that extra traffic, and clean things up, IMO. Instead of going in that direction, this patch completely decouples struct packet_config's 'detect' and 'support' fields. E.g., when the user does "set remote foo-packet off", instead of setting the packet config's 'support' field to PACKET_DISABLE, the 'support' field is not touched at all anymore. That is, we end up respecting this simple table: | packet_config->detect | packet_config->support | should use packet/feature? | |-----------------------+------------------------+----------------------------| | auto | PACKET_ENABLE | PACKET_ENABLE | | auto | PACKET_DISABLE | PACKET_DISABLE | | auto | PACKET_UNKNOWN | PACKET_UNKNOWN | | yes | don't care | PACKET_ENABLE | | no | don't care | PACKET_DISABLE | This is implemented by the new packet_support function. With that, we need to update this pattern throughout: if (remote_protocol_packets[PACKET_foo].support == PACKET_DISABLE) to do this instead: if (packet_support (PACKET_qAttached) == PACKET_DISABLE) where as mentioned, the packet_support function takes struct packet_config's 'detect' field into account, like in the table above. As when the packet is force-disabled or force-enabled, the 'support' field is just ignored, if the command is set back to auto, we'll resume respecting whatever the target said it supports. IOW, the end result is that the 'support' field always represents whether the target actually supports the packet or not. After all that, the manually maintained breakpoint_commands and equivalent fields of struct remote_state can then be eliminated, with references replaced by checking the result of calling the packet_support function on the corresponding packet or feature. This required adding new PACKET_foo enum values for several features that didn't have it yet. (The patch does not add corresponding "set remote foo-packet" style commands though, focusing only on bug fixing and laying the groundwork). Tested on x86_64 Fedora 17, native GDBserver.

Add AVX512 registers support to GDB and GDBserver. This patch adds support for the Intel(R) Advanced Vector Extensions 512 (Intel(R) AVX-512) registers. Native and remote debugging are covered by this patch. Intel(R) AVX-512 is an extension to AVX to support 512-bit wide SIMD registers in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31). The number of available registers in 32-bit mode is still 8 (XMM0-7, YMM0-7, ZMM0-7). The lower 256-bits of the ZMM registers are aliased to the respective 256-bit YMM registers. The lower 128-bits are aliased to the respective 128-bit XMM registers. There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit mode and 64-bit mode.

Stale breakpoint instructions, spurious SIGTRAPS. Without the code portion of the patch, we get these failures: FAIL: gdb.base/break-unload-file.exp: always-inserted on: break: continue FAIL: gdb.base/break-unload-file.exp: always-inserted on: hbreak: continue FAIL: gdb.base/sym-file.exp: stale bkpts: continue to breakpoint: end here They all looks like random SIGTRAPs: continue Continuing. Program received signal SIGTRAP, Trace/breakpoint trap. 0x0000000000400541 in foo () at ../../../src/gdb/testsuite/gdb.base/break-unload-file.c:21 21 } (gdb) FAIL: gdb.base/break-unload-file.exp: always-inserted on: break: continue (This is a regression caused by the remove-symbol-file command series.) break-unload-file.exp is about having breakpoints inserted, and then doing "file". I caught this while writing a test that does "file PROGRAM", while PROGRAM was already loaded, which internally does "file" first, because I wanted to force a breakpoint_re_set, but the test is more explicit in case GDB ever optimizes out that re-set. The problem is that unloading the file with "file" ends up in disable_breakpoints_in_freed_objfile, which marks all breakpoint locations of the objfile as both shlib_disabled, _and_ clears the inserted flag, without actually removing the breakpoints from the inferior. Now, usually, in all-stop, breakpoints will already be removed from the inferior before the user can issue the "file" command, but, with non-stop, or breakpoints always-inserted on mode, breakpoints stay inserted even while the user has the prompt. In the latter case, then, if we let the program continue, and it executes the address where we had previously set the breakpoint, it'll actually execute the breakpoint instruction that we left behind... Now, one issue is that the intent of disable_breakpoints_in_freed_objfile is really to handle the unloading of OBJF_USERLOADED objfiles. These are objfiles that were added with add-symbol-file and that are removed with remove-symbol-file. "add-symbol-file"'s docs in the manual clearly say these commands are used to let GDB know about dynamically loaded code: You would use this command when @var{filename} has been dynamically loaded (by some other means) into the program that is running. Similarly, the online help says: (gdb) help add-symbol-file Load symbols from FILE, assuming FILE has been dynamically loaded. So it makes sense to, like when shared libraries are unloaded through the generic solib machinery, mark the breakpoint locations as shlib_disabled. But, the "file" command is not about dynamically loaded code, it's about the main program. So the patch makes disable_breakpoints_in_freed_objfile skip all objfiles but OBJF_USERLOADED ones, thus skipping the main objfile. Then, the reason that disable_breakpoints_in_freed_objfile was clearing the inserted flag isn't clear, but likely to avoid breakpoint removal errors, assuming remove-symbol-file was called after the dynamic object was already unmapped from the inferior. In that case, it'd okay to simply clear the inserted flag, but not so if the user for example does remove-symbol-file to remove the library because he made a mistake in the library's address, and wants to re-do add-symbol-file with the correct address. To address all that, I propose an alternative implementation, that handles both cases. The patch includes changes to sym-file.exp to cover them. This implementation leaves the inserted flag alone, and handles breakpoint insertion/removal failure gracefully when the locations are in OBJF_USERLOADED objfiles, just like we handle insertion/removal failure gracefully for locations in shared libraries. To try to make sure we aren't patching back stale shadow memory contents into the inferior, in case the program mapped a different library at the same address where we had the breakpoint, without the user having had a chance of remove-symbol-file'ing before, this adds a new memory_validate_breakpoint function that checks if the breakpoint instruction is still in memory. ppc_linux_memory_remove_breakpoint does this unconditionally for all memory breakpoints, and questions whether memory_remove_breakpoint should be changed to do this for all breakpoints. Possibly yes, though I'm not certain, hence this baby-steps patch.

Don't suppress errors inserting/removing hardware breakpoints in shared libraries. As explained in https://sourceware.org/ml/gdb-patches/2008-08/msg00361.html, after a shared library was unloaded, we can no longer insert or remove breakpoints into/from its (no longer present) code segment. That'll fail with memory errors. However, that concern does not apply to hardware breakpoints. By definition, hardware breakpoints are implemented using a mechanism that is not dependent on being able to modify the target's memory. Usually, by setting up CPU debug registers. IOW, we should be able to set hw breakpoints in an unmapped address. We don't seem to have a test that exercises that, so this patch adds one. I noticed the error supression because of a related issue -- the target_insert_hw_breakpoint/target_remove_hw_breakpoint interfaces don't really distinguish "not supported" from "error" return, and so remote.c returns -1 in both cases. This results in hardware breakpoints set in shared libraries silently ending up pending forever even though the target doesn't actually support hw breakpoints.

We probably should improve the insert/remove interface to return a different error code for unsupported. But I chose to fix the error supression first, as it's a deeper and wider issue.

A problem internal to GDB has been detected, further debugging may prove unreliable. FAIL: gdb.base/consecutive-step-over.exp: continue to breakpoint: break here (GDB internal error) The assertion fails, because the code is not expecting that the event thread itself might need another step over. IOW, not expecting that TP in: tp = find_thread_needs_step_over (stepping_thread != NULL, stepping_thread); could be the event thread. A small fix for this would be to clear the event thread's trap_expected earlier, before asserting. But looking deeper, although currently_stepping_or_nexting_callback's intention is finding the thread that is doing a step/next, it also returns the thread that is doing a step-over dance, with trap_expected set. If there ever was a reason for that (it was I who added currently_stepping_or_nexting_callback , but I can't recall why I put trap_expected there in the first place), the only remaining reason nowadays is to aid in implementing switch_back_to_stepped_thread's assertion that is now triggering, by piggybacking on the walk over all threads, thus avoiding a separate walk. This is quite obscure, and I think we can do even better, by merging the walks that look for the stepping thread, and the walk that looks for some thread that might need a step over.

Get trace_regblock_size from metadata instead of event In ctf trace, for each 'R' block, we save it as a "register" event, as defined below in metadata. event { name = "register"; id = 0; fields := struct { ascii contents[440]; }; } Nowadays, we initialize trace_regblock_size by getting the length of "contents" from a "register" event.

Fix PR backtrace/15558 This PR is about an assertion failure in GDB that can be triggered by setting "backtrace limit" to a value that causes GDB to stop unwinding after an inline frame. In this case, an assertion in inline_frame_this_id will trigger: /* We need a valid frame ID, so we need to be based on a valid frame. (...). */ gdb_assert (frame_id_p (*this_id)); Looking at the function: static void inline_frame_this_id (struct frame_info *this_frame, void **this_cache, struct frame_id *this_id) { struct symbol *func; /* In order to have a stable frame ID for a given inline function, we must get the stack / special addresses from the underlying real frame's this_id method. So we must call get_prev_frame. Because we are inlined into some function, there must be previous frames, so this is safe - as long as we're careful not to create any cycles. */ *this_id = get_frame_id (get_prev_frame (this_frame)); we see we're computing the frame id for the inline frame. If this is an inline frame, which is a virtual frame constructed based on debug info, on top of a real stack frame, we should _always_ be able to find where the frame was inlined into, as that ultimately just means peeling off the virtual frames on top of the real stack frame. If there ultimately was no prev (real) stack frame, then we wouldn't have been able to construct the inline frame either, by design. That's what the assertion catches. So we have an inline frame, we should _always_ be able to compute its ID, even if that means bypassing the user backtrace limits to get at the real stack frame's info. The problem is that inline_frame_id calls get_prev_frame, and that takes user backtrace limits into account. Code that wants to bypass the limits calls get_prev_frame_1 instead. Note how get_prev_frame_1 already skips all checks for inline frames: /* If we are unwinding from an inline frame, all of the below tests were already performed when we unwound from the next non-inline frame. We must skip them, since we can not get THIS_FRAME's ID until we have unwound all the way down to the previous non-inline frame. */ if (get_frame_type (this_frame) == INLINE_FRAME) return get_prev_frame_if_no_cycle (this_frame); And note how the related frame_unwind_caller_id function also uses get_prev_frame_1: struct frame_id frame_unwind_caller_id (struct frame_info *next_frame) { struct frame_info *this_frame; /* Use get_prev_frame_1, and not get_prev_frame. The latter will truncate the frame chain, leading to this function unintentionally returning a null_frame_id (e.g., when a caller requests the frame ID of "main()"s caller. */ next_frame = skip_artificial_frames (next_frame); this_frame = get_prev_frame_1 (next_frame); if (this_frame) return get_frame_id (skip_artificial_frames (this_frame)); else return null_frame_id; } get_prev_frame_1 is currently static in frame.c.

Enable DWARF unwinders for SPU This patch enables use of DWARF unwinders for the SPU target. In addition to appending the DWARF unwinders, we also need to install a spu_dwarf_reg_to_regnum that maps the raw stack pointer register to the cooked version (to avoid mismatches with gdbarch_sp_regnum). This also causes confusion with the AX collect handling, so we also install ax_pseudo_register routines to handle the cooked SP. gdb/ 2014-04-17 Ulrich Weigand  <uweigand@de.ibm.com> * spu-tdep.c: Include "dwarf2-frame.h" and "ax.h".

Use address_from_register in dwarf2-frame.c:read_addr_from_reg This patch fixes a problem that prevented use of the Dwarf unwinders on SPU, because dwarf2-frame.c common code did not support the situation where the stack and/or frame pointer is maintained in a *vector* register. This is because read_addr_from_reg is hard-coded to assume that such pointers can be read from registers via a simple get_frame_register / unpack_pointer operation. Now, there *is* a routine address_from_register that calls into the appropriate tdep routines to handle pointer values in "weird" registers like on SPU, but it turns out I cannot simply change dwarf2-frame.c to use address_from_register. This is because address_from_register uses value_from_register to create a (temporary) value, and that routine at some point calls get_frame_id in order to set up that value's VALUE_FRAME_ID entry. However, the dwarf2-frame.c read_addr_from_reg routine will be called during early unwinding (to unwind the frame's CFA), at which point the frame's ID is not actually known yet! This would cause an assert. On the other hand, we may notice that VALUE_FRAME_ID is only needed in the value returned by value_from_register if that value is later used as an lvalue. But this is obviously never done to the temporary value used in address_from_register. So, if we could change address_from_register to not call value_from_register but instead accept constructing a value that doesn't have VALUE_FRAME_ID set, things should be fine. To do that, we can change the value_from_register callback to accept a FRAME_ID instead of a FRAME; the only existing uses of the FRAME argument were either to extract its frame ID, or its gdbarch. (To keep a way of getting at the latter, we also change the callback's type from "f" to "m".) Together with the required follow-on changes in the existing value_from_register implementations (including the default one), this seems to fix the problem. As another minor interface cleanup, I've removed the explicit TYPE argument from address_from_register. This routine really always uses a default pointer type, and in the new implementation it -to some extent- relies on that fact, in that it will now no longer handle types that require gdbarch_convert_register_p handling. gdb: 2014-04-17 Ulrich Weigand  <uweigand@de.ibm.com> * gdbarch.sh (value_from_register): Make class "m" instead of "f".

implement support for "enum class" This adds support for the C++11 "enum class" feature. This is PR c++/15246. I chose to use the existing TYPE_DECLARED_CLASS rather than introduce a new type code. This seemed both simple and clear to me. I made overloading support for the new enum types strict. This is how it works in C++; and it didn't seem like an undue burden to keep this, particularly because enum constants are printed symbolically by gdb.

handle DW_AT_type on an enumeration DWARF allows an enumeration type to have a DW_AT_type. GDB doesn't recognize this, but there is a patch to change GCC to emit it, and a DWARF proposal to further allow an enum type with a DW_AT_type to omit the DW_AT_byte_size.

breakpoint shadowing, take single-step breakpoints into account. Breakpoints are supposed to be transparent to memory accesses. For all kinds of breakpoints breakpoint_xfer_memory hides the breakpoint instructions. However, sss breakpoints aren't tracked like all other breakpoints, and nothing is taking care of hiding them from memory reads. Say, as is, a background step + disassemble will see breakpoints instructions on software step targets. E.g., stepping over this line: while (1); with s& and then "disassemble" would show sss breakpoints. Actually, that's still not be possible to see today, because: - in native Linux, you can't read memory while the program is running. - with Linux gdbserver, you can, but in the all-stop RSP you can't talk to the server while the program is running... - and with non-stop, on software step targets, we presently force the use of displaced-stepping for all single-steps, so no single-step breakpoints are used... I've been working towards making non-stop not force displaced stepping on sss targets, and I noticed the issue then. With that, I indeed see this: (gdb) set remote Z-packet off (gdb) s& (gdb) disassemble main Dump of assembler code for function main: 0x000000000040049c <+0>: push %rbp 0x000000000040049d <+1>: mov %rsp,%rbp 0x00000000004004a0 <+4>: int3 0x00000000004004a1 <+5>: (bad) End of assembler dump. Instead of the correct: (gdb) disassemble main Dump of assembler code for function main: 0x000000000040049c <+0>: push %rbp 0x000000000040049d <+1>: mov %rsp,%rbp 0x00000000004004a0 <+4>: jmp 0x4004a0 <main+4> This is actually one thing that my v1 of the recent "fix a bunch of run control bugs" series was fixing, because it made sss breakpoints be regular breakpoints in the breakpoint chain. But dropped it in the version that landed in the tree, due to some problems. So instead of making sss breakpoints regular breakpoints, go with a simpler fix (at least for now) -- make breakpoint_xfer_memory take software single-step breakpoints into account. After the patch, I get the correct disassemble output. Tested on x86_64 Fedora 17, and also on top of my "use software single-step on x86" series. Also fixes the issue pointed out by Yao at https://sourceware.org/ml/gdb-patches/2014-04/msg00045.html, where the prologue analysis/frame sniffing manages to see software step breakpoint instructions. gdb/ 2014-04-10 Pedro Alves <palves@redhat.com> * breakpoint.c (single_step_breakpoints) (single_step_gdbarch): Move up in the file.

[varobj] false type-changed status for reference to Ada array Given the following variable... BT : Bounded := New_Bounded (Low => 1, High => 3); ... where type Bounded is defined as a simple unconstrained array: type Bounded is array (Integer range <>) of Integer; Creating a varobj for that variable, and immediately asking for varobj updates, GDB says that our varobj changed types! (gdb) -var-create bt * bt ^done,name="bt",numchild="3",value="[3]",type="<ref> array (1 .. 3) of integer",has_more="0" (gdb) -var-update 1 * ^done,changelist=[{name="bt",value="[3]",in_scope="true",type_changed="true",new_type="<ref> array (1 .. 3) of integer",new_num_children="3",has_more="0"}] The expected output for the -var-update command is, in this case: (gdb) -var-update 1 * ^done,changelist=[] The problem occurs because the ada-varobj module does not handle references, and while the references gets stripped when the varobj gets created, it doesn't when computing varobj updates. More specifically, when creating the varobj, varobj_create creates a new value which is a reference to a TYPE_CODE_ARRAY. It then calls install_new_value which calls coerce_ref with the following comment: /* We are not interested in the address of references, and given that in C++ a reference is not rebindable, it cannot meaningfully change. So, get hold of the real value. */ if (value) value = coerce_ref (value); This leaves the varobj's type component still a ref, while the varobj's value is now our array, without the ref. This explains why the "value" field in the varobj indicates an array with 3 elements "[3]" while the "type" field shows a ref to an array. Generally speaking, most users have said that showing the ref was a useful piece of information, so this patch is not touching this part. Next, when the user issues the -var-update request, varobj_update calls value_of_root to compute the varobj's new value as well as determine whether the value's type has changed or not. What happens in a nutshell is that it calls value_of_root_1 (which re-evaluates the expression and returns the corresponding new value), finds that the new value is not NULL, and thus asks whether it has mutated: else if (varobj_value_has_mutated (var, value, value_type (value))) This then indirectly delegates the determination to the language-specific callback, which fails, because it does not handle references. This patch fixes the issue by adjusting varobj_value_has_mutated to expect references, and strip them when seen. This allows the various language-specific implementations to remain unaware of references. gdb/ChangeLog: * varobj.c (varobj_value_has_mutated): If NEW_VALUE is a reference, strip the reference layer before calling the lang_ops value_has_mutated callback. gdb/testsuite/ChangeLog: * gdb.ada/mi_dyn_arr: New testcase.

Remove `expout*' globals from parser-defs.h This commit removes the "expout*" globals from our parser code, turning them into a structure that is passed when an expression needs to be evaluated. This is the initial step to make our parser less "globalized". This is mostly a mechanical patch, which creates a structure containing the "expout*" globals and then modify all the functions that handle them in order to take the structure as argument. It is big, and has been reviewed at least 4 times, so I think everything is covered.

Move the traceframe_available_memory code from memory_xfer_partial_1 down to the targets As a follow-up to [PATCH 7/8] Adjust read_value_memory to use to_xfer_partial https://sourceware.org/ml/gdb-patches/2014-02/msg00384.html this patch moves traceframe_available_memory down to the target side. After this patch, the gdb core code is cleaner, and code on handling unavailable memory is moved to remote/tfile/ctf targets. In details, this patch moves traceframe_available_memory code from memory_xfer_partial_1 to remote target only, so remote target still uses traceframe_info mechanism to check unavailable memory, and use remote_ops to read them from read-only sections.

Fix probe-related internal error on AIX -- Initial message by Tom Tromey: While testing on AIX, I happened to notice an internal error coming from parse_probes. This happens because there are no probes defined on this platform. This patch fixes the problem by changing an assert into an ordinary error, and then changing the relevant caller to cope. This fixes a few tests on AIX; also regtested on x86-64 Fedora 18. -- Followup by Sergio Durigan Junior: By reading the patch (and the original code), I found it a little bit obscure, so I took the liberty to try to improve it. Here's the patch. Could you please take a look and see if it works on AIX (and also if you like the approach)? gdb/ 2014-03-20 Tom Tromey <tromey@redhat.com> Sergio Durigan Junior <sergiodj@redhat.com> * probe.c (parse_probes): Turn assert into an ordinary error. * break-catch-throw.c (re_set_exception_catchpoint): Ignore exceptions when parsing probes.

Fix py-finish-breakpoint.exp with target async. With target async enabled, py-finish-breakpoint.exp triggers an assertion failure. The failure occurs because execute_command re-enters the event loop in some circumstances, and in this case resets the sync_execution flag. Then later GDB reaches this assertion in normal_stop: gdb_assert (sync_execution || !target_can_async_p ()); In detail: #1 - A synchronous execution command is run. sync_execution is set. #2 - A python breakpoint is hit (TARGET_WAITKIND_STOPPED), and the corresponding Python breakpoint's stop method is executed. When and while python commands are executed, interpreter_async is forced to 0. #3 - The Python stop method happens to execute a not-execution-related gdb command. In this case, "where 1". #4 - Seeing that sync_execution is set, execute_command nests a new event loop (although that wasn't necessary; this is the problem). #5 - The linux-nat target's pipe in the event loop happens to be marked. That's normal, due to this in linux_nat_wait: /* If we requested any event, and something came out, assume there may be more. If we requested a specific lwp or process, also assume there may be more. */ The nested event loop thus immediately wakes up and calls target_wait. No thread is actually executing in the inferior, so the target returns TARGET_WAITKIND_NO_RESUMED. #6 - normal_stop is reached. GDB prints "No unwaited-for children left.", and resets the sync_execution flag (IOW, there are no resumed threads left, so the synchronous command is considered completed.) This is already bogus. We were handling a breakpoint! #7 - the nested event loop unwinds/ends. GDB is now back to handling the python stop method (TARGET_WAITKIND_STOPPED), which decides the breakpoint should stop. normal_stop is called for this event. However, normal_stop actually works with the _last_ reported target status: void normal_stop (void) { struct target_waitstatus last; ptid_t last_ptid; struct cleanup *old_chain = make_cleanup (null_cleanup, NULL); ... get_last_target_status (&last_ptid, &last); ... if (last.kind == TARGET_WAITKIND_NO_RESUMED) { gdb_assert (sync_execution || !target_can_async_p ()); target_terminal_ours_for_output (); printf_filtered (_("No unwaited-for children left.\n")); } And due to the nesting in execute command, the last event is now TARGET_WAITKIND_NO_RESUMED, not the actual breakpoint event being handled. This could be seen to be broken in itself, but we can leave fixing that for another pass. The assertion is reached, and fails. execute_command has a comment explaining when it should synchronously wait for events: /* If the interpreter is in sync mode (we're running a user command's list, running command hooks or similars), and we just ran a synchronous command that started the target, wait for that command to end. */ However, the code did not follow this comment -- it didn't check to see if the command actually started the target, just whether the target was executing a sync command at this point. This patch fixes the problem by noting whether the target was executing in sync_execution mode before running the command, and then augmenting the condition to test this as well. 2014-03-20 Tom Tromey <tromey@redhat.com> PR gdb/14135 * top.c (execute_command): Only dispatch events if the command started the target.

This happens when calling functions while handling an event that doesn't cause a user visible stop. dprintf with "set dprintf-style gdb" is one such case. This patch adds a test case that has a breakpoint with a condition that calls a function that returns false, so that regression testing isn't dependent on the implementation of dprintf. The problem happens because run_inferior_call causes GDB to forget that it is running in sync_execution mode, so any event that runs an inferior call causes fetch_inferior_event to display the prompt, even if the event should not result in a user visible stop (that is, gdb resumes the inferior and waits for the next event). This patch fixes the issue by noticing when GDB was in sync_execution mode in run_inferior_call, and taking care to restore this state afterward. gdb/ 2014-03-20 Tom Tromey <tromey@redhat.com> PR cli/15718 * infcall.c: Include event-top.h.

Handle multiple step-overs. This test fails with current mainline. If the program stopped for a breakpoint in thread 1, and then the user switches to thread 2, and resumes the program, GDB first switches back to thread 1 to step it over the breakpoint, in order to make progress. However, that logic only considers the last reported event, assuming only one thread needs that stepping over dance. That's actually not true when we play with scheduler-locking. The patch adds an example to the testsuite of multiple threads needing a step-over before the stepping thread can be resumed. With current mainline, the program re-traps the same breakpoint it had already trapped before.

Fix for even more missed events; eliminate thread-hop code. Even with deferred_step_ptid out of the way, GDB can still lose watchpoints. If a watchpoint triggers and the PC points to an address where a thread-specific breakpoint for another thread is set, the thread-hop code triggers, and we lose the watchpoint: if (ecs->event_thread->suspend.stop_signal == GDB_SIGNAL_TRAP) { int thread_hop_needed = 0; struct address_space *aspace = get_regcache_aspace (get_thread_regcache (ecs->ptid)); /* Check if a regular breakpoint has been hit before checking for a potential single step breakpoint. Otherwise, GDB will not see this breakpoint hit when stepping onto breakpoints. */ if (regular_breakpoint_inserted_here_p (aspace, stop_pc)) { if (!breakpoint_thread_match (aspace, stop_pc, ecs->ptid)) thread_hop_needed = 1; ^^^^^^^^^^^^^^^^^^^^^ } And on software single-step targets, even without a thread-specific breakpoint in the way, here in the thread-hop code: else if (singlestep_breakpoints_inserted_p) { ... if (!ptid_equal (singlestep_ptid, ecs->ptid) && in_thread_list (singlestep_ptid)) { /* If the PC of the thread we were trying to single-step has changed, discard this event (which we were going to ignore anyway), and pretend we saw that thread trap. This prevents us continuously moving the single-step breakpoint forward, one instruction at a time. If the PC has changed, then the thread we were trying to single-step has trapped or been signalled, but the event has not been reported to GDB yet. There might be some cases where this loses signal information, if a signal has arrived at exactly the same time that the PC changed, but this is the best we can do with the information available. Perhaps we should arrange to report all events for all threads when they stop, or to re-poll the remote looking for this particular thread (i.e. temporarily enable schedlock). */ CORE_ADDR new_singlestep_pc = regcache_read_pc (get_thread_regcache (singlestep_ptid)); if (new_singlestep_pc != singlestep_pc) { enum gdb_signal stop_signal; if (debug_infrun) fprintf_unfiltered (gdb_stdlog, "infrun: unexpected thread," " but expected thread advanced also\n"); /* The current context still belongs to singlestep_ptid. Don't swap here, since that's the context we want to use. Just fudge our state and continue. */ stop_signal = ecs->event_thread->suspend.stop_signal; ecs->event_thread->suspend.stop_signal = GDB_SIGNAL_0; ecs->ptid = singlestep_ptid; ecs->event_thread = find_thread_ptid (ecs->ptid); ecs->event_thread->suspend.stop_signal = stop_signal; stop_pc = new_singlestep_pc; } else { if (debug_infrun) fprintf_unfiltered (gdb_stdlog, "infrun: unexpected thread\n"); thread_hop_needed = 1; stepping_past_singlestep_breakpoint = 1; saved_singlestep_ptid = singlestep_ptid; } } } we either end up with thread_hop_needed, ignoring the watchpoint SIGTRAP, or switch to the stepping thread, again ignoring that the SIGTRAP could be for some other event. The new test added by this patch exercises both paths. So the fix is similar to the deferred_step_ptid fix -- defer the thread hop to _after_ the SIGTRAP had a change of passing through the regular bpstat handling. If the wrong thread hits a breakpoint, we'll just end up with BPSTAT_WHAT_SINGLE, and if nothing causes a stop, keep_going starts a step-over. Most of the stepping_past_singlestep_breakpoint mechanism is really not necessary -- setting the thread to step over a breakpoint with thread->trap_expected is sufficient to keep all other threads locked. It's best to still keep the flag in some form though, because when we get to keep_going, the software single-step breakpoint we need to step over is already gone -- an optimization done by a follow up patch will check whether a step-over is still be necessary by looking to see whether the breakpoint is still there, and would find the thread no longer needs a step-over, while we still want it. Special care is still needed to handle the case of PC of the thread we were trying to single-step having changed, like in the old code. We can't just keep_going and re-step it, as in that case we can over-step the thread (if it was already done with the step, but hasn't reported it yet, we'd ask it to step even further). That's now handled in switch_back_to_stepped_thread. As bonus, we're now using a technique that doesn't lose signals, unlike the old code -- we now insert a breakpoint at PC, and resume, which either reports the breakpoint immediately, or any pending signal.

PR breakpoints/7143 - Watchpoint does not trigger when first set Say the program is stopped at a breakpoint, and the user sets a watchpoint. When the program is next resumed, GDB will first step over the breakpoint, as explained in the manual: @value {GDBN} normally ignores breakpoints when it resumes execution, until at least one instruction has been executed. If it it did not do this, you would be unable to proceed past a breakpoint without first disabling the breakpoint. This rule applies whether or not the breakpoint already existed when your program stopped. However, GDB currently also removes watchpoints, catchpoints, etc., and that means that the first instruction off the breakpoint does not trigger the watchpoint, catchpoint, etc. testsuite/gdb.base/watchpoint.exp has a kfail for this. The PR proposes installing watchpoints only when stepping over a breakpoint, but that misses catchpoints, etc. A better fix would instead work from the opposite direction -- remove only real breakpoints, leaving all other kinds of breakpoints inserted. But, going further, it's really a waste to constantly remove/insert all breakpoints when stepping over a single breakpoint (generating a pair of RSP z/Z packets for each breakpoint), so the fix goes a step further and makes GDB remove _only_ the breakpoint being stepped over, leaving all others installed. This then has the added benefit of reducing breakpoint-related RSP traffic substancialy when there are many breakpoints set. gdb/ 2014-03-20 Pedro Alves <palves@redhat.com> PR breakpoints/7143 * breakpoint.c (should_be_inserted): Don't insert breakpoints that are being stepped over.

Fix missing breakpoint/watchpoint hits, eliminate deferred_step_ptid. Consider the case of the user doing "step" in thread 2, while thread 1 had previously stopped for a breakpoint. In order to make progress, GDB makes thread 1 step over its breakpoint first (with all other threads stopped), and once that is over, thread 2 then starts stepping (with thread 1 and all others running free, by default). If GDB didn't do that, thread 1 would just trip on the same breakpoint immediately again. This is what the prepare_to_proceed / deferred_step_ptid code is all about. However, deferred_step_ptid code resumes the target with: resume (1, GDB_SIGNAL_0); prepare_to_wait (ecs); return; Recall we were just stepping over a breakpoint when we get here. That means that _nothing_ had installed breakpoints yet! If there's another breakpoint just after the breakpoint that was just stepped, we'll miss it. The fix for that would be to use keep_going instead. However, there are more problems. What if the instruction that was just single-stepped triggers a watchpoint? Currently, GDB just happily resumes the thread, losing that too... Missed watchpoints will need yet further fixes, but we should keep those in mind. So the fix must be to let the trap fall through the regular bpstat handling, and only if no breakpoint, watchpoint, etc. claims the trap, shall we switch back to the stepped thread. Now, nowadays, we have code at the tail end of trap handling that does exactly that -- switch back to the stepped thread (switch_back_to_the_stepped_thread). So the deferred_step_ptid code is just standing in the way, and can simply be eliminated, fixing bugs in the process. Sweet. The comment about spurious "Switching to ..." made me pause, but is actually stale nowadays. That isn't needed anymore. previous_inferior_ptid used to be re-set at each (internal) event, but now it's only touched in proceed and normal stop. The two tests added by this patch fail without the fix.

Power: Correct little-endian e500v2 GPR frame offsets This change corrects GPR frame offset calculation for the e500v2 processor. On this target, featuring the SPE APU, GPRs are 64-bit and are held in stack frames whole with the use of `evstdd' and `evldd' instructions. Their integer 32-bit part occupies the low-order word and therefore its offset varies between the two endiannesses possible. * rs6000-tdep.c (rs6000_frame_cache): Correct little-endian GPR offset into SPE pseudo registers.

This is because normal_stop, as commanded by the result of bpstat_print, skips printing frame info in this case (it's an "event", not a "breakpoint"), and when the interpreter is MI, mi_on_normal_stop skips calling print_stack_frame, as the normal_stop call was already done with the MI uiout. This explains why the async output is different even with a CLI command. Its because in async mode, the mi_on_normal_stop path is always taken; it is always reached with the MI uiout, because the stop is handled from the event loop, instead of from within `proceed -> wait_for_inferior -> normal_stop' with the interpreter overridden, as in sync mode. This patch fixes the issue by making all cases output the same *stopped event, by factoring out the print code from normal_stop, and using it from mi_on_normal_stop as well. I chose the *stopped output without a frame, mainly because that is what you already get if you use MI execution commands, the commands frontends are supposed to use (except when implementing a console). This patch makes it simpler to tweak the MI output differently if desired, as we only have to change the centralized print_stop_event (taking into account whether the uiout is MI-like), and all different modes will change accordingly. Tested on x86_64 Fedora 17, no regressions. The mi-solib.exp test no longer fails in async mode with this patch, so the patch removes the kfail. 2014-03-18 Pedro Alves <palves@redhat.com> PR gdb/13860 * inferior.h (print_stop_event): Declare. * infrun.c (print_stop_event): New, factored out from ...

Both form a valid GNAT encoding for a packed array type. Trying to print A2 (1) can make GDB crash. This is because A2 is defined as a reference to a GNAT encoding for a packed array. When decoding constrained packed arrays, the ada_coerce_ref subprogram follows references and returns a fixed type from the target type, peeling the GNAT encoding for packed arrays. The remaining code assumes that the resulting type is still such an encoding while we only have a standard GDB array type, hence the crash: arr = ada_coerce_ref (arr); [...] type = decode_constrained_packed_array_type (value_type (arr)); decode_constrained_packed_array_type assumes that its argument is such an encoding. From its front comment: /* The array type encoded by TYPE, where ada_is_constrained_packed_array_type (TYPE). */ This patch simply replaces the call to ada_coerce_ref with a call to coerce_ref in order to avoid prematurely transforming the packed array type as a side-effect. This way, the remaining code will always work with a GNAT encoding. gdb/ChangeLog: * ada-lang.c (decode_constrained_packed_array): Perform a minimal coercion for reference with coerce_ref instead of ada_coerce_ref.

Rename native-only terminal related functions. Looking at target_terminal_inferior etc. in async mode, I realized that the naming of the terminal_inferior, terminal_ours, etc. functions doesn't really give a clue that they're meant for the native target only. This patch renames them. There's already child_terminal_info using the child_ prefix, and, they're most prominently installed by inf-child.c, so I went with the child_ prefix. I dropped "inferior" from a couple to make the name match the corresponding target method. Tested on x86_64 Fedora 17, and cross built for mingw. I didn't test gnu-nat.c, but I think the change is as obvious as it gets. I grepped the tree looking for other potential spots that would need adjustment but this is all I found.

Don't mention "Unix" in native target name. I find the mention of "Unix" unnecessary (and really slightly a lie) on GNU/Linux in a couple of places: (gdb) maint print target-stack The current target stack is: - multi-thread (multi-threaded child process.) - child (Unix child process) - exec (Local exec file) - None (None) (gdb) help target child Unix child process (started by the "run" command). (gdb) target child Use the "run" command to start a Unix child process. It's also odd that e.g., the Windows port says "Unix" in reaction to "target child" (it was already that way before Windows used inf-child.c): (gdb) target child Use the "run" command to start a Unix child process. (gdb) So drop "Unix", going in the direction of saying mostly the same on all native targets: (gdb) maint print target-stack The current target stack is: - multi-thread (multi-threaded child process.) - - child (Unix child process) + - child (Child process) - exec (Local exec file) - None (None) (gdb) help target child - Unix child process (started by the "run" command). + Child process (started by the "run" command).

Factor out foreground/background execution command preparation. All execution commands currently have this pattern: /* If we must run in the background, but the target can't do it, error out. */ if (async_exec && !target_can_async_p ()) error (_("Asynchronous execution not supported on this target.")); /* If we are not asked to run in the bg, then prepare to run in the foreground, synchronously. */ if (!async_exec && target_can_async_p ()) { /* Simulate synchronous execution. */ async_disable_stdin (); } This patch factors that into a shared function. attach_command installs a cleanup to re-enable stdin, but that's not necessary, as per the comment in prepare_execution_command. In any case, if someday it turns out necessary, we have a single place to install it now.

Support for HWbreak/watchpoint across fork/vfork on arm-native This patch updates arm native support for hwbreak-/watchpoints to enable support for hwbreak-/watchpoints across fork/vfork. This involves changes to hwbreak-/watchpoint insertion mechanism to the modern way, by marking debug registers as needing update, but only really updating them on resume, which is necessary for supporting watchpoints in non-stop mode. This also updates a previously maintained per thread hwbreak-/watchpoint cache to a per process cache which allows target specific code to come in sync with gdb-linux calls to threads create/destroy and process fork/exit hooks.

fix regressions with target-async A patch in the target cleanup series caused a regression when using record with target-async. Version 4 of the patch is here: https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html The immediate problem is that record supplies to_can_async_p and to_is_async_p methods, but does not supply a to_async method. So, when target-async is set, record claims to support async -- but if the underlying target does not support async, then the to_async method call will end up in that method's default implementation, namely tcomplain. This worked previously because the record target used to provide a to_async method; one that (erroneously, only at push time) checked the other members of the target stack, and then simply dropped to_async calls in the "does not implement async" case. My first thought was to simply drop tcomplain as the default for to_async. This works, but Pedro pointed out that the only reason record has to supply to_can_async_p and to_is_async_p is that these default to using the find_default_run_target machinery -- and these defaults are only needed by "run" and "attach". So, a nicer solution presents itself: change run and attach to explicitly call into the default run target when needed; and change to_is_async_p and to_can_async_p to default to "return 0". This makes the target stack simpler to use and lets us remove the method implementations from record. This is also in harmony with other plans for the target stack; namely trying to reduce the impact of find_default_run_target. This approach makes it clear that find_default_is_async_p is not needed -- it is asking whether a target that may not even be pushed is actually async, which seems like a nonsensical question. While an improvement, this approach proved to introduce the same bug when using the core target. Looking a bit deeper, the issue is that code in "attach" and "run" may need to use either the current target stack or the default run target -- but different calls into the target API in those functions could wind up querying different targets. This new patch makes the target to use more explicit in "run" and "attach". Then these commands explicitly make the needed calls against that target. This ensures that a single target is used for all relevant operations. This lets us remove a couple find_default_* functions from various targets, including the dummy target. I think this is a decent understandability improvement. One issue I see with this patch is that the new calls in "run" and "attach" are not very much like the rest of the target API. I think fundamentally this is due to bad factoring in the target API, which may need to be fixed for multi-target. Tackling that seemed ambitious for a regression fix. While working on this I noticed that there don't seem to be any test cases that involve both target-async and record, so this patch changes break-precsave.exp to add some. It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

With patch applied, it becomes: (gdb) goto-bookmark 1.1 goto-bookmark: invalid bookmark number '1.1'. gdb: 2014-03-06 Yao Qi <yao@codesourcery.com> * reverse.c (goto_bookmark_command): Add local 'p'. Emit error early if get_number returns zero. Use 'p' instead of 'args'.

Fix PR16508 This patch fixes PR16508, which is about MI "-trace-find frame-number 0" behaves differently from CLI "tfind 0". In CLI, we check both status->running and status->filename, but in MI, we only check status->running, which looks wrong to me. This patch moves the code of checking to a new function check_trace_running, and use it in both CLI and MI. This patch also adds a test case pr16508.exp, which fails without this fix, and passes with the fix applied.

Those breakpoint instructions are no longer installed in target memory they're stale in the code cache.

I stumbled upon this when writing a patch to infrun.c, that made handle_inferior_event & co fill in the cache before breakpoints were removed from the target. Recall that wait_for_inferior flushes the dcache for every event. So in that case, always-inserted mode was not necessary to trigger this. It's just a convenient way to expose the issue. The dcache works at the raw memory level. We need to update it whenever memory is written, no matter what kind of target memory object was originally passed down by the caller. The issue is that the dcache update code isn't reached when a caller explicitly writes raw memory. Breakpoint insertion/removal is one such case -- mem-break.c uses target_write_read_memory/target_write_raw_memory. The fix is to move the dcache update code from memory_xfer_partial_1 to raw_memory_xfer_partial so that it's always reachable. When we do that, we can actually simplify a series of things. memory_xfer_partial_1 no longer needs to handle writes for any kind of memory object, and therefore dcache_xfer_memory no longer needs to handle writes either. So the latter (dcache_xfer_memory) and its callees can be simplified to only care about reads. While we're touching dcache_xfer_memory's prototype, might as well rename it to reflect that fact that it only handles reads, and make it follow the new target_xfer_status/xfered_len style. This made me notice that dcache_xfer_memory loses the real error status if a memory read fails: we could have failed to read due to TARGET_XFER_E_UNAVAILABLE, for instance, but we always return TARGET_XFER_E_IO, hence the FIXME note. I felt that fixing that fell out of the scope of this patch. Currently dcache_xfer_memory handles the case of a write failing. The whole cache line is invalidated when that happens. However, dcache_update, the sole mechanism for handling writes that will remain after the patch, does not presently handle that scenario. That's a bug. The patch makes it handle that, by passing down the target_xfer_status status from the caller, so that it can better decide what to do itself. While I was changing the function's prototype, I constified the myaddr parameter, getting rid of the need for the cast as seen in its existing caller.

change probes to be program-space-independent This changes the probes to be independent of the program space. After this, when a probe's address is needed, it is determined by applying offsets at the point of use. This introduces a bound_probe object, similar to bound minimal symbols. Objects of this type are used when it's necessary to pass a probe and its corresponding objfile. This removes the backlink from probe to objfile, which was primarily used to fetch the architecture to use. This adds a get_probe_address function which calls a probe method to compute the probe's relocated address. Similarly, it adds an objfile parameter to the semaphore methods so they can do the relocation properly as well. 2014-03-03 Tom Tromey <tromey@redhat.com> * break-catch-throw.c (fetch_probe_arguments): Use bound probes. * breakpoint.c (create_longjmp_master_breakpoint): Use get_probe_address.

DWARF: Read constant-class addresses correctly Starting with DWARF version 4, the description of the DW_AT_high_pc attribute was amended to say: if it is of class constant, the value is an unsigned integer offset which when added to the low PC gives the address of the first location past the last instruction associated with the entity. A change was made in Apr 27th, 2012 to reflect that change: | commit 91da14142c0171e58a91ad58a32fd010b700e761 | Author: Mark Wielaard <mjw@redhat.com> | Date: Fri Apr 27 18:55:19 2012 +0000 | | * dwarf2read.c (dwarf2_get_pc_bounds): Check DW_AT_high_pc form to | see whether it is an address or a constant offset from DW_AT_low_pc. | (dwarf2_record_block_ranges): Likewise. | (read_partial_die): Likewise. Unfortunately, this new interpretation is now used regardless of the CU's DWARF version. It turns out that one of WindRiver's compilers (FTR: Diabdata 4.4) is generating DWARF version 2 info with DW_AT_high_pc attributes improperly using the data4 form. Because of that, we miscompute all high PCs incorrectly. This leads to a lot of symtabs having overlapping ranges, which in turn causes havoc in pc-to-symtab-and-line translations. One visible effect is when inserting a breakpoint on a given function: (gdb) b world Breakpoint 1 at 0x4005c4 The source location of the breakpoint is missing. The output should be: (gdb) b world Breakpoint 1 at 0x4005c8: file dw2-rel-hi-pc-world.c, line 24. What happens in this case is that the pc-to-SAL translation first starts be trying to find the symtab associated to our PC using each symtab's ranges. Because of the high_pc miscomputation, many symtabs end up matching, and the heuristic trying to select the most probable one unfortunately returns one that is unrelated (it really had no change in this case to do any better). Once we have the wrong symtab, the start searching the associated linetable, where the addresses are correct, thus finding no match, and therefore no SAL. This patch is an attempt at handling the situation as gracefully as we can, without guarantees. It introduces a new function "attr_value_as_address" which uses the correct accessor for getting the value of a given attribute. It then adjust the code throughout this unit to use this function instead of assuming that addresses always have the DW_FORM_addr format. It also fixes the original issue of miscomputing the high_pc by limiting the new interpretation of constant form DW_AT_high_pc attributes to units using DWARF version 4 or later. gdb/ChangeLog: * dwarf2read.c (attr_value_as_address): New function.

make "file" use the BFD cache better Right now the "file" command will discard the exec_bfd and then possibly open a new one. If this ends up reopening the same file, it can cause needless work by gdb -- destroying all the per-BFD data just to re-read it again. This patch changes the code to hold a reference to the old exec_bfd while opening the new one. The possible downside of this is a higher peak memory use. 2014-02-26 Tom Tromey <tromey@redhat.com> * exec.c (exec_file_attach): Hold a reference to exec_bfd.

add short-circuit logic to elfread.c If minimal symbols have already been read into a per-BFD object, then a symbol reader can skip re-reading them. This changes the ELF reader to do so. We only skip the work if the file is ELF+DWARF. If it has stabs or mdebug sections, then I think extra information is computed during the minsym creation pass; and so we must still repeat it. Eventually even this will go away, once all symbol types have switched to being progspace-independent. In the meantime this has no negative effect -- it is just a missing optimization for a small set of users. This change also required a somewhat non-obvious change to the OBJSTAT accounting code. If a symbol reader skips re-reading minimal symbols, then the corresponding OBJSTAT will not be updated. This leads to a test failure in gdb.base/maint.exp. To fix this, I've moved the needed stat field out of objfile and into the per-BFD object. 2014-02-26 Tom Tromey <tromey@redhat.com> * elfread.c (elf_read_minimal_symbols): Return early if minimal symbols have already been read.

move minimal symbols to per-bfd Now that minimal symbols are independent of the program space, we can move them to the per-BFD object. This lets us save memory in the multi-inferior case; and, once the symbol readers are updated, time. The other prerequisite for this move is that all the objects referred to by the minimal symbols have a lifetime at least as long as the per-BFD object. I think this is satisfied partially by this patch (moving the copied names there) and partially by earlier patches moving the demangled name hash. This patch contains a bit of logic to avoid creating new minimal symbols if they have already been read for a given BFD. This allows us to avoid trying to update all the symbol readers for this condition. At first glance this may seem like a hack, but some symbol readers mix psym and minsym reading, and would require logic just like this regardless -- and it is simpler and less error-prone to just do the work in a central spot. 2014-02-26 Tom Tromey <tromey@redhat.com> * minsyms.c (lookup_minimal_symbol, iterate_over_minimal_symbols) (lookup_minimal_symbol_text, lookup_minimal_symbol_by_pc_name) (lookup_minimal_symbol_solib_trampoline) (lookup_minimal_symbol_by_pc_section_1) (lookup_minimal_symbol_and_objfile): Update.

change minsyms not to be relocated at read-time This removes the runtime offsets from minsyms. Instead, these offsets will now be applied whenever the minsym's address is computed. This patch redefines MSYMBOL_VALUE_ADDRESS to actually use the offsets from the given objfile. Then, it updates all the symbol readers, changing them so that they do not add in the section offset when creating the symbol.

start change to progspace independence This patch starts changing minimal symbols to be independent of the program space. Specifically, it adds a new objfile parameter to MSYMBOL_VALUE_ADDRESS and changes all the code to use it. This is needed so we can change gdb to apply the section offset when a minsym's address is computed, as opposed to baking the offsets into the symbol itself. A few spots still need the unrelocated address. For these, we introduce MSYMBOL_VALUE_RAW_ADDRESS. As a convenience, we also add the new macro BMSYMBOL_VALUE_ADDRESS, which computes the address of a bound minimal symbol. This just does the obvious thing with the fields. Note that this change does not actually enable program space independence. That requires more changes to gdb. However, to ensure that these changes compile properly, this patch does add the needed section lookup code to MSYMBOL_VALUE_ADDRESS -- it just ensures it has no effect at runtime by multiplying the offset by 0. 2014-02-26 Tom Tromey <tromey@redhat.com> * ada-lang.c (ada_main_name): Update.

use bound_minsym as result for lookup_minimal_symbol et al This patch changes a few minimal symbol lookup functions to return a bound_minimal_symbol rather than a pointer to the minsym. This change helps prepare gdb for computing a minimal symbol's address at the point of use. Note that this changes even those functions that ostensibly search a single objfile. That was necessary because, in fact, those functions can search an objfile and its separate debug objfiles; and it is important for the caller to know in which objfile the minimal symbol was actually found. The bulk of this patch is mechanical. 2014-02-26 Tom Tromey <tromey@redhat.com> * ada-lang.c (ada_update_initial_language): Update.

change minsym representation In a later patch we're going to change the minimal symbol address calculation to apply section offsets at the point of use. To make it simpler to catch potential problem spots, this patch changes the representation of minimal symbols and introduces new minimal-symbol-specific variants of the various accessors. This is necessary because it would be excessively ambitious to try to convert all the symbol types at once. The core of this change is just renaming a field in minimal_symbol; the rest is just a fairly mechanical rewording. 2014-02-26 Tom Tromey <tromey@redhat.com> * symtab.h (struct minimal_symbol) <mginfo>: Rename from ginfo.

introduce minimal_symbol_upper_bound This introduces minimal_symbol_upper_bound and changes various bits of code to use it. Since this function is intimately tied to the implementation of minimal symbol tables, I believe it belongs in minsyms.c. The new function is extracted from find_pc_partial_function_gnu_ifunc. This isn't a "clean" move because the old function interleaved the caching and the computation; but this doesn't make sense for the new code. 2014-02-26 Tom Tromey <tromey@redhat.com> * blockframe.c (find_pc_partial_function_gnu_ifunc): Use bound minimal symbols.

[Python] Make regexp collection printers work with typedefs as well. Consider the following type for which we would like to provide a pretty-printer and manage it via RegexpCollectionPrettyPrinter: typedef long time_t; Currently, this does not work because this framework only considers the type's tag name: typename = gdb.types.get_basic_type(val.type).tag if not typename: return None This patch extends it to use the type's name if the basic type does not have a tag name, thus allowing the framework to also work with typedefs like the above. gdb/ChangeLog: * python/lib/gdb/printing.py (RegexpCollectionPrettyPrinter): Use the type's name if its basic type does not have a tag. gdb/testsuite/ChangeLog: * testsuite/gdb.python/py-pp-re-notag.c: New file. * testsuite/gdb.python/py-pp-re-notag.ex: New file. * testsuite/gdb.python/py-pp-re-notag.p: New file.

DWARF: Set enum type "flag_enum" and "unsigned" flags at type creation. Consider the following Ada code: -- An array whose index is an enumeration type with 128 enumerators. type Enum_T is (Enum_000, Enum_001, [...], Enum_128); type Table is array (Enum_T) of Boolean; When the compiler is configured to generate pure DWARF debugging info, trying to print type Table's description yields: ptype pck.table type = array (enum_000 .. -128) of boolean The expected output was: ptype pck.table type = array (enum_000 .. enum_128) of boolean The DWARF debugging info for our array looks like this: <1><44>: Abbrev Number: 5 (DW_TAG_array_type) <45> DW_AT_name : pck__table <50> DW_AT_type : <0x28> <2><54>: Abbrev Number: 6 (DW_TAG_subrange_type) <55> DW_AT_type : <0x5c> <59> DW_AT_lower_bound : 0 <5a> DW_AT_upper_bound : 128 The array index type is, by construction with the DWARF standard, a subrange of our enumeration type, defined as follow: <2><5b>: Abbrev Number: 0 <1><5c>: Abbrev Number: 7 (DW_TAG_enumeration_type) <5d> DW_AT_name : pck__enum_t <69> DW_AT_byte_size : 1 <2><6b>: Abbrev Number: 8 (DW_TAG_enumerator) <6c> DW_AT_name : pck__enum_000 <7a> DW_AT_const_value : 0 [etc] Therefore, while processing these DIEs, the array index type ends up being a TYPE_CODE_RANGE whose target type is our enumeration type. But the problem is that we read the upper bound as a negative value (-128), which is then used as is by the type printer to print the array upper bound. This negative value explains the "-128" in the output. To understand why the range type's upper bound is read as a negative value, one needs to look at how it is determined, in read_subrange_type: orig_base_type = die_type (die, cu); base_type = check_typedef (orig_base_type); [... high is first correctly read as 128, but then ...] if (!TYPE_UNSIGNED (base_type) && (high & negative_mask)) high |= negative_mask; The negative_mask is applied, here, because BASE_TYPE->FLAG_UNSIGNED is not set. And the reason for that is because the base_type was only partially constructed during the call to die_type. While the enum is constructed on the fly by read_enumeration_type, its flag_unsigned flag is only set later on, while creating the symbols corresponding to the enum type's enumerators (see process_enumeration_scope), after we've already finished creating our range type - and therefore too late. My first naive attempt at fixing this problem consisted in extracting the part in process_enumeration_scope which processes all enumerators, to generate the associated symbols, but more importantly set the type's various flags when necessary. However, this does not always work well, because we're still in the subrange_type's scope, and it might be different from the scope where the enumeration type is defined. So, instead, what this patch does to fix the issue is to extract from process_enumeration_scope the part that determines whether the enumeration type should have the flag_unsigned and/or the flag_flag_enum flags set. It turns out that, aside from the code implementing the loop, this part is fairly independent of the symbol creation. With that part extracted, we can then use it at the end of our enumeration type creation, to produce a type which should now no longer need any adjustment. Once the enumeration type produced is correctly marked as unsigned, the subrange type's upper bound is then correctly read as an unsigned value, therefore giving us an upper bound of 128 instead of -128. gdb/ChangeLog: * dwarf2read.c (update_enumeration_type_from_children): New function, mostly extracted from process_structure_scope.

To be const-correct, we need to copy that buffer to a non-const buffer, and pass the copy to write_child. This is actually what target.c:default_xfer_partial itself does, when calling into the ops->deprecated_xfer_memory hook. Tested by cross-building djgpp gdb, on x86-64 Fedora 17. gdb/ 2014-02-26 Pedro Alves <palves@redhat.com> * go32-nat.c (my_write_child): New function.

DWARF: Add array DW_AT_bit_stride and DW_AT_byte_stride support Consider the following declarations in Ada... type Item is range -32 .. 31; for Item'Size use 6; type Table is array (Natural range 0 .. 4) of Item; pragma Pack (Table); ... which declare a packed array whose elements are 6 bits long. The debugger currently does not notice that the array is packed, and thus prints values of this type incorrectly. This can be seen in the "ptype" output: (gdb) ptype table type = array (0 .. 4) of foo.item Normally, the debugger should print: (gdb) ptype table type = array (0 .. 4) of foo.item <packed: 6-bit elements> The debugging information for this array looks like this: .uleb128 0xf # (DIE (0x15c) DW_TAG_array_type) .long .LASF9 # DW_AT_name: "pck__table" .byte 0x6 # DW_AT_bit_stride .long 0x1a9 # DW_AT_type .uleb128 0x10 # (DIE (0x16a) DW_TAG_subrange_type) .long 0x3b # DW_AT_type .byte 0 # DW_AT_lower_bound .byte 0x4 # DW_AT_upper_bound .byte 0 # end of children of DIE 0x15c The interesting part is the DW_AT_bit_stride attribute, which tells the size of the array elements is 6 bits, rather than the normal element type's size. This patch adds support for this attribute by first creating gdbtypes.c::create_array_type_with_stride, which is an enhanced version of create_array_type taking an extra parameter as the stride. The old create_array_type can then be re-implemented very simply by calling the new create_array_type_with_stride. We can then use this new function from dwarf2read, to create arrays with or without stride. gdb/ChangeLog: * gdbtypes.h (create_array_type_with_stride): Add declaration. * gdbtypes.c (create_array_type_with_stride): New function, renaming create_array_type, but with an added parameter called "bit_stride". (create_array_type): Re-implement using create_array_type_with_stride. * dwarf2read.c (read_array_type): Add support for DW_AT_byte_stride and DW_AT_bit_stride attributes. gdb/testsuite/ChangeLog: * gdb.dwarf2/arr-stride.c: New file. * gdb.dwarf2/arr-stride.exp: New file. The test, relying purely on generating an assembly file, only verifies the type description of our array. But I was also able to verify manually that the debugger print values of these types correctly as well (which was not the case prior to this patch).

The issue is that the bpstat_check_breakpoint_conditions logic of "wrong thread" is missing the "wrong task" check. This is usually harmless, because the thread hop code in infrun.c code that handles wrong-task-hitting-breakpoint does check for task-specific breakpoints (within breakpoint_thread_match): /* Check if a regular breakpoint has been hit before checking for a potential single step breakpoint. Otherwise, GDB will not see this breakpoint hit when stepping onto breakpoints. */ if (regular_breakpoint_inserted_here_p (aspace, stop_pc)) { if (!breakpoint_thread_match (aspace, stop_pc, ecs->ptid)) thread_hop_needed = 1; } IOW, usually, when one only has a task specific breakpoint at a given address, things work correctly. Put another task-specific or non-task-specific breakpoint there, and things break. A patch that eliminates the special thread hop code in infrun.c is what exposed this, as after that GDB solely relies on bpstat_check_breakpoint_conditions to know whether the right or wrong task hit a breakpoint. IOW, given the latent bug, Ada task-specific breakpoints become non-task-specific, and that is caught by the testsuite, as: break break_me task 3 Breakpoint 2 at 0x4030b0: file /home/pedro/gdb/mygit/src/gdb/testsuite/gdb.ada/tasks/foo.adb, line 27.

Re-implement ia64-linux-nat.c::ia64_linux_xfer_partial [description of this patch and ChangeLog entry by Joel Brobecker] The recent implementation was questionable, and if it worked, it was only by chance because the requested length is large enough that only one read was sufficient.

Use 16-bit integer type for rl78 register pairs. This patch changes rl78-tdep.c so that a 16-bit type is used for register pairs instead of a pointer type as was previously the case. This will cause these register pairs to be displayed as integers instead of as a data address with a 0xf0000 ORed in. E.g. registers ax, bc, de, and hl might now be displayed like this: (gdb) info registers ax bc de hl ax 0x6 6 bc 0x0 0 de 0x10c3 4291 hl 0x108d 423 Whereas, before, they were displayed as follows: (gdb) info registers ax bc de hl ax 0xf0006 0xf0006 bc 0xf0000 0xf0000 de 0xf10c3 0xf10c3 hl 0xf108d 0xf108d These pairs are 16 bit quantities and should be displayed as such. This change also affects the way that the banked register pairs are displayed. Within GDB, the banked register pairs are named bank0_rp0, bank0_rp1, .., bank3_rp2, bank3_rp3. However, these register pairs need to be used as addresses in DWARF expressions. I have added 16 pseudo registers corresponding to banked register pairs. These new pseudo registers are all hidden from the user and have a pointer type. Values from these registers are intended to be used in DWARF expressions. Therefore, rl78_dwarf_reg_to_regnum() has been adjusted to return these new pseudo register numbers. I had a much simpler patch which only changed the types, but it showed a number of regressions due to integer values from the banked register pairs being used as part of an address expression. This current patch shows no regressions and now displays values of register pairs correctly. * rl78-tdep.c ( RL78_BANK0_RP0_PTR_REGNUM, RL78_BANK0_RP1_PTR_REGNUM) (RL78_BANK0_RP2_PTR_REGNUM, RL78_BANK0_RP3_PTR_REGNUM) (RL78_BANK1_RP0_PTR_REGNUM, RL78_BANK1_RP1_PTR_REGNUM) (RL78_BANK1_RP2_PTR_REGNUM, RL78_BANK1_RP3_PTR_REGNUM) (RL78_BANK2_RP0_PTR_REGNUM, RL78_BANK2_RP1_PTR_REGNUM) (RL78_BANK2_RP2_PTR_REGNUM, RL78_BANK2_RP3_PTR_REGNUM) (RL78_BANK3_RP0_PTR_REGNUM, RL78_BANK3_RP1_PTR_REGNUM) (RL78_BANK3_RP2_PTR_REGNUM, RL78_BANK3_RP3_PTR_REGNUM): New constants.

Rename TARGET_XFER_E_UNAVAILABLE to TARGET_XFER_UNAVAILABLE Nowadays, TARGET_XFER_E_UNAVAILABLE isn't regarded as an error in to_xfer_partial interface, so _E_ looks odd. This patch is to replace TARGET_XFER_E_UNAVAILABLE with TARGET_XFER_UNAVAILABLE, and change its value from -2 to 2. Since there is no comparison on the value of 'enum target_xfer_status', so it should be safe. gdb: 2014-02-24 Yao Qi <yao@codesourcery.com> * target.h (enum target_xfer_status) <TARGET_XFER_E_UNAVAILABLE>: Rename it to ... <TARGET_XFER_UNAVAILABLE>: ... it with setting value 2 explicitly.

Revert previous tweaks As we migrate to the new to_xfer_partial interface, some of previous tweaks become unnecessary, we don't have to check traceframe is selected in each target implementation, so this patch below is reverted.

Fix for PR tdep/16397: SystemTap SDT probe support for x86 doesn't work with "triplet operands" This is the continuation of what Joel proposed on: <https://sourceware.org/ml/gdb-patches/2013-12/msg00977.html> Now that I have already submitted and pushed the patch to split i386_stap_parse_special_token into two smaller functions, it is indeed simpler to understand this patch. It occurs because, on x86, triplet displacement operands are allowed (like "-4+8-20(%rbp)"), and the current parser for this expression is buggy. It does not correctly extract the register name from the expression, which leads to incorrect evaluation. The parser was also being very "generous" with the expression, so I included a few more checks to ensure that we're indeed dealing with a triplet displacement operand. This patch also includes testcases for the two different kind of expressions that can be encountered on x86: the triplet displacement (explained above) and the three-argument displacement (as in "(%rbx,%ebx,-8)"). The tests are obviously arch-dependent and are placed under gdb.arch/.

Simplify windows-nat.c::get_module_name Now that get_module_name is no longer called for handling DLL events, we can simplify it a bit, knowing that the only use is to get the executable's filename. While doing so, we adjusted the implementation a bit to avoid references to DLLs, renamed it to make its more-targeted usage more explicit, moved it right before the only function that uses it. We also remove the use of hard-coded length for the buffers being used. gdb/ChangeLog: * windows-nat.c (get_module_name): Delete.

Windows: Rely purely on event info when handling DLL load event When a DLL gets loaded an the debugger gets a debug event about it, the currently implementation in handle_load_dll currently tries to fetch the DLL's name by first iterating over all DLLs known to the system. It should be sufficient to rely on the name provided with the event, however, especially in the situation we are now, where we now know that we're past the statup phase for our inferior. This patch therefore simplifies windows-nat.c::handle_load_dll to only rely on the event's lpImageName. It also updates the function's comment to document the assumption regarding not being during the inferior's startup phase. And while at it, it fixes the function documentation, which was probably unintentionally inherited from another function (perhaps windows_wait). gdb/ChangeLog: * windows-nat.c (handle_load_dll): Rewrite this function's introductory comment. Remove code using get_module_name to get the DLL's name.

Ignore DLL load/unload events during inferior initialization. This patch aims at simplifying DLL handling during the inferior initialization (process creation during the "run", or during an "attach"). Instead of processing each DLL load event, which is sometimes incomplete, we ignore these events until the inferior has completed its startup phase, and then just iterate over all DLLs via EnumProcessModules. gdb/ChangeLog: * windows-nat.c (get_windows_debug_event): Ignore LOAD_DLL_DEBUG_EVENT and UNLOAD_DLL_DEBUG_EVENT if windows_initialization_done == 0.

Deprecate windows-specific dll-symbols command and aliases The "dll-symbols" command, specific to native Windows platforms, gives the impression that the symbols were not loaded, first because it completes silently, and second because the "info shared" output does not get updated after the command completes: (gdb) dll-symbols C:\WINDOWS\syswow64\rpcrt4.dll (gdb) info shared From To Syms Read Shared Object Library [...] 0x77e51000 0x77ee2554 No C:\WINDOWS\system32\rpcrt4.dll (we exected the "Syms Read" column to read "Yes"). As far as I can tell, the symbols actually do get loaded, but completely independently from the solib framework, which explains the silent loading and the fact that the "Syms Read" column does not get updated. See windows-nat.c::safe_symbol_file_add_stub, which calls symbol_file_add instead of calling solib_add. But, aside from the fact that the "Syms Read" status does not get updated, I also noticed that it does not take into account the DLL's actual load address when loading its symbols. As a result, I believe that we get it wrong if the DLL does not get loaded at the prefered address. Rather than trying to fix this command, there does not seem to be a reason other than historical for having Windows-specific commands which essentially re-implements the "sharedlibrary" command. The command interface is slightly different (the latter takes a regexp rather than a plain filename), but it should be just as easy to use the "sharedlibrary" command, or its "share" alias, as usisng the "dll-symbols" command. For instance: (gdb) share rpcrt4.dll Reading symbols from C:\WINDOWS\system32\rpcrt4.dll...(no debugging symbols found)...done. Loaded symbols for C:\WINDOWS\system32\rpcrt4.dll (gdb) info shared From To Syms Read Shared Object Library [...] 0x77e51000 0x77ee2554 Yes (*) C:\WINDOWS\system32\rpcrt4.dll This patch therefore deprecates the "dll-symbols" command, as well as its two aliases "add-shared-symbol-files" and "assf", with a view of deleting them as soon as the 7.8 branch gets cut. gdb/ChangeLog: * windows-nat.c (_initialize_windows_nat): Deprecate the "dll-symbols" command.

common/ptid.h: Mention that process_stratum targets should prefer ptid.lwp. It's best that we standardize on process_stratum targets using the ptid.lwp field to store thread ids.

This patch adds a comment in that direction to struct ptid's definition. gdb/ 2014-02-19 Pedro Alves <palves@redhat.com> * common/ptid.h (struct ptid): Mention that process_stratum targets should prefer ptid.lwp.

remote.c: Use the ptid.lwp field to store remote thread ids rather than ptid.tid. From GDB's perspective, independently of how the target really implements threads, gdb/remote sees all threads as if kernel/system threads. A rationale along theses lines led to gdbserver storing thread ids in ptid.lwp in all ports. Because remote.c is currently using ptid.tid, we can't make gdbserver and gdb share bits of remote-specific code that manipulates ptids (e.g., write_ptid/read_ptid). This patch thus makes remote.c use ptid.lwp instead of ptid.tid. I believe that on the GDB side too, it's best that we standardize on process_stratum targets using the ptid.lwp field to store thread ids anyway. The idea being leave the ptid.tid field free for any thread_stratum target that might want to sit on top.

add target method delegation This patch replaces some code in the record targets with target method delegation. record-full.c stores pointers to many target methods when the record target is pushed. Then it later delegates some calls via these. This is wrong because it violates the target stack contract. In particular it is ok to unpush a target at any stratum, but record-full does not keep track of this, so it could potentially call into an unpushed target. This patch fixes the problem by using the newly-introduced generic approach to target delegation for the methods in question. 2014-02-19 Tom Tromey <tromey@redhat.com> * record-full.c (record_full_beneath_to_resume_ops) (record_full_beneath_to_resume, record_full_beneath_to_wait_ops) (record_full_beneath_to_wait) (record_full_beneath_to_store_registers_ops) (record_full_beneath_to_store_registers) (record_full_beneath_to_xfer_partial_ops) (record_full_beneath_to_xfer_partial) (record_full_beneath_to_insert_breakpoint_ops) (record_full_beneath_to_insert_breakpoint) (record_full_beneath_to_remove_breakpoint_ops) (record_full_beneath_to_remove_breakpoint) (record_full_beneath_to_stopped_by_watchpoint) (record_full_beneath_to_stopped_data_address) (record_full_beneath_to_async, tmp_to_resume_ops, tmp_to_resume) (tmp_to_wait_ops, tmp_to_wait, tmp_to_store_registers_ops) (tmp_to_store_registers, tmp_to_xfer_partial_ops) (tmp_to_xfer_partial, tmp_to_instmp_to_insert_breakpoint_ops) (tmp_to_insert_breakpoint, tmp_to_remove_breakpoint_ops) (tmp_to_remove_breakpoint, tmp_to_stopped_by_watchpoint) (tmp_to_stopped_data_address, tmp_to_async): Remove.

add make-target-delegates This patch adds a new script, call make-target-delegates, which auto-generates some target delegation code based on annotations in target.h.

It doesn't, however, add any actual annotations to the target methods, leaving these for separate patches. 2014-02-19 Tom Tromey <tromey@redhat.com> PR build/7701: * target-delegates.c: New file. * target.c: Include target-delegates.c.

add "this" pointers to more target APIs A subsequent pass introduces delegation helper functions to the target API. This delegation is much cleaner if the target_ops pointer is directly available at delegation time. This patch adds the "this" pointer to various to_* methods for this purpose. This updates a number of ports which I am unable to test. Please give them a look-over.

move some rsp bits into rsp-low.h This moves various low-level remote serial protocol bits into common/rsp-low.[ch]. This is as close to a pure move as possible. There are some redundancies remaining but those will be dealt with in a subsequent patch. Note that the two variants of remote_escape_output disagreed on the treatment of "*". On the theory that quoting cannot hurt but the absence possibly can, I chose the gdbserver variant to be the canonical one. 2014-02-12 Tom Tromey <tromey@redhat.com> * tracepoint.c: Include rsp-low.h. * remote.h (hex2bin, bin2hex, unpack_varlen_hex): Don't declare. * remote.c: Include rsp-low.h.

Explicitly mark vtables as code space Ports for Hardvard architectures will typically have in their pointer_to_address hook a check for TYPE_CODE_SPACE in their "pointer_to_address" gdbarch method. E.g., rl78's: /* Is it a code address? */ if (TYPE_CODE (TYPE_TARGET_TYPE (type)) == TYPE_CODE_FUNC || TYPE_CODE (TYPE_TARGET_TYPE (type)) == TYPE_CODE_METHOD || TYPE_CODE_SPACE (TYPE_TARGET_TYPE (type)) || TYPE_LENGTH (type) == 4) return rl78_make_instruction_address (addr); else return rl78_make_data_address (addr); The avr port is similar. The vtable type is a struct type gdb itself bakes. Being neither a function, nor a method, and absent explicit flagging as residing in code space, ends up being considered data. This patch marks the type as code when it is created, on the theory that this is needed for all Hardvard architectures. I believe this should make no difference on archs with flat address space. Testing on x86-64 GNU/Linux shows no changes. gdb/ 2014-02-12 Pedro Alves <palves@redhat.com> Kevin Buettner <kevinb@redhat.com> * gnu-v3-abi.c (build_gdb_vtable_type): Return a type marked with TYPE_INSTANCE_FLAG_CODE_SPACE. Kevin Buettner, at <https://sourceware.org/ml/gdb-patches/2014-02/msg00338.html>, writes, re. rl78: This patch, for rl78 using the default multilib, fixes 5 failures in gdb.cp/casts.exp, 2 failures in gdb.cp/class2.exp, 115 failures in gdb.mi/mi-var-rtti.exp, and 2 failures in gdb.python/py-value.exp. It introduces 9 failures (regressions) in gdb.mi/mi-var-rtti.exp. One of the regressions is: FAIL: gdb.mi/mi-var-rtti.exp: list children of s.public in type_update_when_use_rtti The relevant lines from the log file from a pre-patch test run are as follows: -var-list-children S.public ^done,numchild="1",children=[child={name="S.public.ptr",exp="ptr",numchild="1",type="Base *",thread-id="1"}],has_more="0" (gdb) PASS: gdb.mi/mi-var-rtti.exp: list children of s.public in type_update_when_use_rtti Expecting: \^done,numchild=".*",children=\[child={name="S.public.ptr.public",exp="public",numchild="1"(,thread-id="[0-9]+")?}.*\],has_more="0" Expecting: ^(-var-list-children S\.public\.ptr [ ]+)?(\^done,numchild=".*",children=\[child={name="S.public.ptr.public",exp="public",numchild="1"(,thread-id="[0-9]+")?}.*\],has_more="0"[ ]+[(]gdb[)] [ ]*) The same set of lines for the failing (post-patch) run are instead: -var-list-children S.public &"warning: can't find linker symbol for virtual table for `Base' value\n" &"warning: found `typeinfo for __cxxabiv1::__vmi_class_type_info' instead\n" &"warning: can't find linker symbol for virtual table for `Base' value\n" &"warning: found `typeinfo for __cxxabiv1::__vmi_class_type_info' instead\n" &"warning: can't find linker symbol for virtual table for `Base' value\n" &"warning: found `typeinfo for __cxxabiv1::__vmi_class_type_info' instead\n" ^done,numchild="1",children=[child={name="S.public.ptr",exp="ptr",numchild="1",type="Base *",thread-id="1"}],has_more="0" (gdb) FAIL: gdb.mi/mi-var-rtti.exp: list children of s.public in type_update_when_use_rtti Expecting: \^done,numchild=".*",children=\[child={name="S.public.ptr.public",exp="public",numchild="1"(,thread-id="[0-9]+")?}.*\],has_more="0" Expecting: ^(-var-list-children S\.public\.ptr [ ]+)?(\^done,numchild=".*",children=\[child={name="S.public.ptr.public",exp="public",numchild="1"(,thread-id="[0-9]+")?}.*\],has_more="0"[ ]+[(]gdb[)] [ ]*) Note that the difference between these are the warnings regarding linker symbols. Aside from the warnings, the result is the same. I.e. gdb produces the correct answer despite the warnings. The reason for the other 8 failures is the same: the test harness is not expecting these warnings. I spent some time (a while ago) looking at the reason for these warnings. As I recall, we are now getting further along in the type resolution process than we were without my patch. I.e. for the example above, the code in question never got to the point where it was looking for the specified linker symbol. So it seems to me that, at worst, my patch exposes some other problem, but is not directly the cause of the problem.

H8/300: Fix gdb<->sim register mapping. Currently, printing the H8/300 ccr register when debugging with the sim is broken: (gdb) target sim ... (gdb) load ... (gdb) start ... Breakpoint 1, foo (i=0x0 <foo>) at main.c:4 4 { (gdb) info registers ccr Register 13 is not available '13' is the ccr pseudo-register. This pseudo-register provides an 8-bit view into the raw ccr register (regno=8). The problem is that the H8/300 port does not define a register_sim_regno gdbarch hook, and thus when fetching the raw register off of the sim, we end up in legacy_register_sim_regno trying to figure out the sim register number for the raw CCR register: int legacy_register_sim_regno (struct gdbarch *gdbarch, int regnum) { /* Only makes sense to supply raw registers. */ gdb_assert (regnum >= 0 && regnum < gdbarch_num_regs (gdbarch)); /* NOTE: cagney/2002-05-13: The old code did it this way and it is suspected that some GDB/SIM combinations may rely on this behavour. The default should be one2one_register_sim_regno (below). */ if (gdbarch_register_name (gdbarch, regnum) != NULL && gdbarch_register_name (gdbarch, regnum)[0] != '\0') return regnum; else return LEGACY_SIM_REGNO_IGNORE; } Because the raw ccr register does not have a name (so that it is hidden from the user), that returns LEGACY_SIM_REGNO_IGNORE. That means that we never actually read the value of the raw ccr register. Before the <unavailable> support, this must have meant that ccr was _always_ read as 0... At least, I'm not seeing how this ever worked. The fix for that is adding a gdbarch_register_sim_regno hook that maps all raw registers. Looking at sim/h8300/sim-main.h, I believe the sim's register numbers are compatible with gdb's, so no actual convertion is necessary. gdb/ 2014-02-12 Pedro Alves <palves@redhat.com> * h8300-tdep.c (h8300_register_sim_regno): New function.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

gdb/elfread.c: Enable ifunc support on ARM. There are two failures in the gnu-ifunc.exp test on ARM. These are due to the failure to resolve the correct target function when attempting to breakpoint a GNU ifunc resolved function: (gdb) break gnu_ifunc Breakpoint 4 at gnu-indirect-function resolver at 0x2aacb5a2 when gnu_ifunc has been resolved this should actually be: (gdb) break gnu_ifunc Breakpoint 4 at 0x868c There are two reasons for this. The first is that ARM does not have a separate .got.plt section so looking this up will always fail. The second is that the Thumb bit needs to be stripped from the address to allow it to be reliably compared when inserting into the ifunc cache. Tested with no regressions on arm-linux-gnueabihf and x86_64-unknown-linux-gnu. gdb/ChangeLog: 2014-02-10 Will Newton <will.newton@linaro.org> * elfread.c (elf_rel_plt_read): Look for a .got section if looking up .got.plt fails.

Add gdbarch_in_function_epilogue_p hook for sparc64. watchpoint_update and watchpoint_cond avoid checking for watchpoints when we are located at a function epilogue in the current frame. This is done in order to avoid using corrupted local registers and unwinding a corrupted/destroyed stack. The code determining whether we are in a function epilogue is provided by the backends via the gdbarch_in_function_epilogue_p hook. This commit adds such a hook for sparc64 targets. 2014-02-10 Jose E. Marchesi <jose.marchesi@oracle.com> * sparc-tdep.c (sparc_in_function_epilogue_p): New function.

Make sure we don't resume the stepped thread by accident. Say: <stopped at a breakpoint in thread 2> (gdb) thread 3 (gdb) step The above triggers the prepare_to_proceed/deferred_step_ptid process, which switches back to thread 2, to step over its breakpoint before getting back to thread 3 and "step" it. If while stepping over the breakpoint in thread 2, a signal arrives, and it is set to pass/nostop, we'll set a step-resume breakpoint at the supposed signal-handler resume address, and call keep_going. The problem is that we were supposedly stepping thread 3, and that keep_going delivers a signal to thread 2, and due to scheduler-locking off, resumes everything else, _including_ thread 3, the thread we want stepping. This means that we lose control of thread 3 until the next event, when we stop everything. The end result for the user, is that GDB lost control of the "step". Here's the current infrun debug output of the above, with the testcase in the patch below: infrun: clear_proceed_status_thread (Thread 0x2aaaab8f5700 (LWP 11663)) infrun: clear_proceed_status_thread (Thread 0x2aaaab6f4700 (LWP 11662)) infrun: clear_proceed_status_thread (Thread 0x2aaaab4f2b20 (LWP 11659)) infrun: proceed (addr=0xffffffffffffffff, signal=144, step=1) infrun: prepare_to_proceed (step=1), switched to [Thread 0x2aaaab6f4700 (LWP 11662)] infrun: resume (step=1, signal=0), trap_expected=1, current thread [Thread 0x2aaaab6f4700 (LWP 11662)] at 0x40098f infrun: wait_for_inferior () infrun: target_wait (-1, status) = infrun: 11659 [Thread 0x2aaaab6f4700 (LWP 11662)], infrun: status->kind = stopped, signal = SIGUSR1 infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x40098f infrun: random signal 30 Program received signal SIGUSR1, User defined signal 1. infrun: signal arrived while stepping over breakpoint infrun: inserting step-resume breakpoint at 0x40098f infrun: resume (step=0, signal=30), trap_expected=0, current thread [Thread 0x2aaaab6f4700 (LWP 11662)] at 0x40098f ^^^ this is a wildcard resume. infrun: prepare_to_wait infrun: target_wait (-1, status) = infrun: 11659 [Thread 0x2aaaab6f4700 (LWP 11662)], infrun: status->kind = stopped, signal = SIGTRAP infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x40098f infrun: BPSTAT_WHAT_STEP_RESUME infrun: resume (step=1, signal=0), trap_expected=1, current thread [Thread 0x2aaaab6f4700 (LWP 11662)] at 0x40098f ^^^ step-resume hit, meaning the handler returned, so we go back to stepping thread 3. infrun: prepare_to_wait infrun: target_wait (-1, status) = infrun: 11659 [Thread 0x2aaaab6f4700 (LWP 11662)], infrun: status->kind = stopped, signal = SIGTRAP infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x40088b infrun: switching back to stepped thread infrun: Switching context from Thread 0x2aaaab6f4700 (LWP 11662) to Thread 0x2aaaab8f5700 (LWP 11663) infrun: resume (step=1, signal=0), trap_expected=0, current thread [Thread 0x2aaaab8f5700 (LWP 11663)] at 0x400938 infrun: prepare_to_wait infrun: target_wait (-1, status) = infrun: 11659 [Thread 0x2aaaab8f5700 (LWP 11663)], infrun: status->kind = stopped, signal = SIGTRAP infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x40093a infrun: keep going infrun: resume (step=1, signal=0), trap_expected=0, current thread [Thread 0x2aaaab8f5700 (LWP 11663)] at 0x40093a infrun: prepare_to_wait infrun: target_wait (-1, status) = infrun: 11659 [Thread 0x2aaaab8f5700 (LWP 11663)], infrun: status->kind = stopped, signal = SIGTRAP infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x40091e infrun: stepped to a different line infrun: stop_stepping [Switching to Thread 0x2aaaab8f5700 (LWP 11663)] 69 (*myp) ++; /* set breakpoint child_two here */ ^^^ we stopped at the wrong line.

Return early in target_xfer_partial when LEN is zero. Nowadays, argument LEN of to_xfer_partial can be zero in some cases, and each implementation may do nothing and return zero, indicating transfer is done. That is fine. However, when we change to_xfer_partial to return target_xfer_status, we have to check every return value of most of to_xfer_partial implementations, return TARGET_XFER_DONE if return value is zero. This patch simplifies this by checking LEN in target_xfer_partial, and return 0 if LEN is zero. Regression tested on x86_84-linux. Is it OK? gdb: 2014-02-07 Yao Qi <yao@codesourcery.com> * target.c (target_xfer_partial): Return zero if LEN is zero.

Avoid bison-isms when using yacc. YYPRINT is a bison-ism so c_print_token() ends up being unused when yacc is used which makes gcc unhappy. Make sure we only define YYPRINT and c_print_token() when bison is used to generate the parser. gdb/ChangeLog: * c-exp.y (YYPRINT, c_print_token): Only define if YYBISON is defined.

Use rs->buf after getpkt Hi, The following code snippet looks wrong to me char *buf = rs->buf; getpkt (&rs->buf, &rs->buf_size, 0); packet_ok (buf, ); if rs->buf is reallocated in getpkt, buf points to an out of dated memory.

PowerPC64 ELFv2 ABI: skip global entry point code This patch handles another aspect of the ELFv2 ABI, which unfortunately requires common code changes. In ELFv2, functions may provide both a global and a local entry point. The global entry point (where the function symbol points to) is intended to be used for function-pointer or cross-module (PLT) calls, and requires r12 to be set up to the entry point address itself. The local entry point (which is found at a fixed offset after the global entry point, as defined by bits in the symbol table entries' st_other field), instead expects r2 to be set up to the current TOC. Now, when setting a breakpoint on a function by name, you really want that breakpoint to trigger either way, no matter whether the function is called via its local or global entry point. Since the global entry point will always fall through into the local entry point, the way to achieve that is to simply set the breakpoint at the local entry point. One way to do that would be to have prologue parsing skip the code sequence that makes up the global entry point. Unfortunately, this does not work reliably, since -for optimized code- GDB these days will not actuall invoke the prologue parsing code but instead just set the breakpoint at the symbol address and rely on DWARF being correct at any point throughout the function ... Unfortunately, I don't really see any way to express the notion of local entry points with the current set of gdbarch callbacks. Thus this patch adds a new callback, skip_entrypoint, that is somewhat analogous to skip_prologue, but is called every time GDB needs to determine a function start address, even in those cases where GDB decides to not call skip_prologue. As a side effect, the skip_entrypoint implementation on ppc64 does not need to perform any instruction parsing; it can simply rely on the local entry point flags in the symbol table entry. With this implemented, two test cases would still fail to set the breakpoint correctly, but that's because they use the construct: gdb_test "break *hello" Now, using "*hello" explicitly instructs GDB to set the breakpoint at the numerical value of "hello" treated as function pointer, so it will by definition only hit the global entry point. I think this behaviour is unavoidable, but acceptable -- most people do not use this construct, and if they do, they get what they asked for ... In one of those two test cases, use of this construct is really not appropriate. I think this was added way back when as a means to work around prologue skipping problems on some platforms. These days that shouldn't really be necessary any more ... For the other (step-bt), we really want to make sure backtracing works on the very first instruction of the routine. To enable that test also on powerpc64le-linux, we can modify the code to call the test function via function pointer (which makes it use the global entry point in the ELFv2 ABI). gdb/ChangeLog: * gdbarch.sh (skip_entrypoint): New callback. * gdbarch.c, gdbarch.h: Regenerate. * symtab.c (skip_prologue_sal): Call gdbarch_skip_entrypoint. * infrun.c (fill_in_stop_func): Likewise. * ppc-linux-tdep.c: Include "elf/ppc64.h".

PowerPC64 ELFv2 ABI: structure passing / return Another significant difference in the ELFv2 ABI is that "homogeneous" floating-point and vector aggregates, i.e. aggregates the consist (recursively) only of members of the same floating-point or vector type, are passed in a series of floating-point / vector registers, as if they were seperate parameters. (This is similar to the ARM ABI.) This applies to both calls and returns. In addition when returning any aggregate of up to 16 bytes, ELFv2 now used general-purpose registers. This patch adds support for these aspects of the ABI, which is relatively straightforward after the refactoring patch to ppc-sysv-tdep.c. gdb/ChangeLog: * ppc-sysv-tdep.c (ppc64_aggregate_candidate): New routine.

PowerPC64 ELFv2 ABI: no function descriptors This implements the most significant difference with the ELFv2 ABI: we no longer use function descriptors. The patch consists mostly of switching off code to deal with descriptors :-) In addition, when calling an inferior function, we no longer need to provide its TOC in r2. Instead, ELFv2 code expects to be called with r12 pointing to the code address itself. gdb/ChangeLog: * ppc-linux-tdep.c (ppc_linux_init_abi): Only call set_gdbarch_convert_from_func_ptr_addr and set_gdbarch_elf_make_msymbol_special for ELFv1. * ppc-sysv-tdep.c (ppc64_sysv_abi_push_param): Only handle function descriptors on ELFv1.

PowerPC64 ELFv2 ABI: base support This is the first patch of a series to implement support for the PowerPC ELFv2 ABI. While powerpc64le-linux will use ELFv2, and the existing powerpc64-linux code will continue to use ELFv1, in theory ELFv2 is also defined for big-endian systems (and ELFv1 was also defined for little-endian systems). Therefore this patch adds a new tdep->elf_abi variable to decide which ABI version to use. This is detected from the ELF header e_flags value; if this is not present, we default to ELFv2 on little-endian and ELFv1 otherwise. This patch does not yet introduce any actual difference in GDB's handling of the two ABIs. Those will be added by the remainder of this patch series. For an overview of the changes in ELFv2, have a look at the comments in the patch series that added ELFv2 to GCC, starting at: http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01144.html gdb/ChangeLog: * ppc-tdep.h (enum powerpc_elf_abi): New data type.

PowerPC64 little-endian fixes: 128-bit DFP parameters / registers The powerpc64le-linux ABI specifies that when a 128-bit DFP value is passed in a pair of floating-point registers, the first register holds the most-significant part of the value. This is as opposed to the usual rule on little-endian systems, where the first register would hold the least-significant part. This affects two places in GDB, the read/write routines for the 128-bit DFP pseudo-registers, and the function call / return sequence. For the former, current code already distinguishes between big- and little-endian targets, but gets the latter wrong. This is presumably because *GCC* also got it wrong, and GDB matches the old GCC behavior. But GCC is now fixed: http://gcc.gnu.org/ml/gcc-patches/2013-11/msg02145.html so GDB needs to be fixed too. (Old code shouldn't really be an issue since there is no code "out there" so far that uses dfp128 on little-endian ...) gdb/ChangeLog: * ppc-sysv-tdep.c (ppc64_sysv_abi_push_freg): Use correct order within a register pair holding a DFP 128-bit value on little-endian.

PowerPC64 little-endian fixes: 32-bit DFP parameters Passing a 32-bit DFP in register needs to use the least-significant part of the register.

PowerPC64 little-endian fixes: VSX tests and pseudo-regs Many VSX test were failing on powerpc64le-linux, since -as opposed to the AltiVec tests- there never were little-endian versions of the test patterns. This patch adds such patterns, along the lines of altivec-regs.exp. In addition, there is an actual code change required: For those VSX registers that overlap a floating-point register, the FP register overlaps the most-significant half of the VSX register both on big- and little-endian systems. However, on little-endian systems, that half is stored at an offset of 8 bytes (not 0). This works already for the "real" FP registers, but current code gets it wrong for the "extended" pseudo FP register GDB generates for the second half of the VSX register bank. This patch updates the corresponding pseudo read/write routines to take the appropriate offset into consideration. gdb/ChangeLog: * rs6000-tdep.c (efpr_pseudo_register_read): Use correct offset of the overlapped FP register within the VSX register on little- endian platforms. (efpr_pseudo_register_write): Likewise. gdb/testsuite/ChangeLog: * gdb.arch/vsx-regs.exp: Check target endianness. Provide variants of the test patterns for use on little-endian systems.

PowerPC64 little-endian fixes: structure passing When passing a small structure in a GPR, the ABI specifies that it should be passed in the least-significant bytes of the register (or stack slot). On big-endian systems, this means the value needs to be stored at an offset, which is what current code does. However, on little-endian systems, the least-significant bytes are addresses with offset 0. This patch fixes that. gdb/ChangeLog: * ppc-sysv-tdep.c (ppc64_sysv_abi_push_val): Use correct offset on little-endian when passing small structures.

Refactor ppc64 function call and return value handling This patch refactors the ppc64 function call and return value handling code in ppc-sysv-tdep.c. The main problem to be addressed by this refactoring is the code duplication caused by certain aggregate types: According to the ABI, some types are to be decomposed into component types for parameter and return value handling. For example, complex types are to be passed as if the real and imaginary component were separate arguments. Similarly, certain OpenCL vector types are passed as if they were multiple separate arguments of the vector element type. With the new ELFv2 ABI, there is another case: "homogeneous aggregates" (e.g. a struct containing 4 floats) are passed in multiple floating point registers as well. Unfortunately, the current code is not structured to easily model these ABI properties. For example, code to pass complex values re-implements code to pass the underlying (floating-point) type. This has already led to some unfortunate code duplication, and with the addition of ELFv2 ABI support, I would have had to add yet more such duplication. To avoid that, I've decided to refactor the code in order to re-use subroutines that handle the "base" types when handling those aggregate types. This was not intended to cause any difference on current (ELFv1) ABI code, but in fact it fixes a bug: FAIL: gdb.base/varargs.exp: print find_max_float_real(4, fc1, fc2, fc3, fc4) This was caused by the old code in ppc64_sysv_abi_push_float incorrectly handling floating-point arguments to vararg routines, which just happens to work out correctly automatically in the refactored code ... gdb/ChangeLog: * ppc-sysv-tdep.c (get_decimal_float_return_value): Update comment.

New Ada maintenance command to ignore descriptive types (DWARF). Currently, Ada debugging requires the use of certain GNAT-specific encodings, which are generated by the compiler. These encodings were created a long time ago to work around the fairly limited capabilities of the stabs debugging format. With DWARF, the vast majority of the encodings could be abandoned in favor of a pure DWARF approach. In order to make it easier to evaluate the quality of the DWARF debugging information generated by the compiler, and how the debugger handles it, we are introducing a small Ada-specific maintenance setting which changes the debugger's behavior to ignore descriptive types. Descriptive types are artificial types generated by the compiler purely to give the debugger hints as to how to properly decode certain properties of a type. For instance, for array types, it generates a parallel type whose name is the name of the array suffixed with ___XA, whose contents tells us what the array's index type is, and possibly its bounds. See GCC's gcc/ada/exp_dbug.ads for the full description of all encodings. This is only a first step, as this setting does not deactivate all encodings; More settings dedicated to each type of encoding will likely be implemented in the future, as we make progress. gdb/ChangeLog: * ada-lang.c (maint_set_ada_cmdlist, maint_show_ada_cmdlist): New static globals.

btrace: initiate teardown when closing record btrace target The to_teardown_btrace target method is used to free btrace resources during shutdown when target record has already been unpushed and we can't reliably talk to a remote target to disable branch tracing. Tracing resources are freed for each thread when the thread is removed; both on the GDB side and on the gdbserver side. In the remote case, the remote target that provides to_teardown_btrace to free the GDB side resources has already been unpushed when threads are destroyed. This results in a complaint "You can't do this ..." and in a few bytes of memory leaked for each thread. Initiate btrace teardown in record_btrace_close, so the remote target is still in place. 2014-01-27 Markus Metzger <markus.t.metzger@intel.com> * record-btrace.c (record_btrace_close): Call btrace_teardown for all threads.

ada-lang.c: Really include "ui-out.h". Currently, ada-lang.c pretends to include "ui-out.h" as follow: #ifdef UI_OUT #include "ui-out.h" #endif However, UI_OUT is never defined as far as I can tell. This is confirmed by rebuilding with a #error pragma inside the #ifdef UI_OUT block, which never triggers. Since this unit makes references to declarations from ui-out.h, this patch simply removes the #ifdef/#endif condition. This has not been an error so far because "ui-out.h" indirectly gets included, via one of the other .h files being included. gdb/ChangeLog: * ada-lang.c: Remove "#ifdef UI_OUT" condition for including "ui-out.h".

Try printing array range using the name of its index type type Char_Table is array (Character range Character'First .. Character'Last) of Natural; Trying to print the type description of this type currently yields: (gdb) ptype char_table type = array ('["00"]' ..

[Ada] Array bound incorrectly printed for array indexed by enum subrange Consider the following declarations: type Range_Type is (One, Two, Three); type Array_Type is array (Range_Type range One .. Two) of Integer; A : Array_Type := (1, 2); Trying to print A can yield: (gdb) print a $1 = (one => 1, 2) The bound of the first element should not have been printed, since "one" is the first enumerate of type Range_Type. Similarly, with the following declarations: type Array2_Type is array (Range_Type range Two .. Three) of Integer; A2 : Array2_Type := (2, 3); GDB is failing to print the bound of the first element of "A2": (gdb) print a2 $2 = (2, 3) This is because the index type for both types Array_Type and Array2_Type are subranges (by DWARF definition for arrays), of an anonymous subrange type. When deciding whether to print the bound of the first element, we handle subranges, but only up to one level. This patch enhanced the code to handle any number of subrange levels. gdb/ChangeLog: * ada-valprint.c (print_optional_low_bound): Get index_type's target type for as long as it is a TYPE_CODE_RANGE. No testcase with this patch, but this will be tested via the testcase of another patch, which uses the DWARF assembler to generate debugging info for an array indexed by an enum.

Remove assert in procfs.c::procfs_make_note_section (x86-solaris) On x86-solaris, the gcore command sometimes triggers the following internal error: (gdb) gcore /[...]/procfs.c:5523: internal-error: procfs_make_note_section: Assertion `thread_args.note_data != note_data' failed. The problem is extremely elusive, for reasons that will become clearer as I explain what is going on. The program used to produce this issue was really simple: | void break_me (void) { } | | int | main (void) | { | break_me (); | return 0; | } The procfs_make_note_section builds a buffer incrementally with the contents of the core's notes section. The interesting bits are: char *note_data = NULL; [...] note_data = (char *) elfcore_write_prpsinfo (obfd, note_data, note_size, fname, psargs); This is the first call to bfd's elfcore which initializes note_data. After that, we have a few more calls, which keep updating notes_data and note_size, but our interest lies in the following part of the function: thread_args.note_data = note_data; [...] proc_iterate_over_threads (pi, procfs_corefile_thread_callback, &thread_args); /* There should be always at least one thread. */ gdb_assert (thread_args.note_data != note_data); The comment implies that the assert is to verify that our loop iterated over at least one thread. The check is relying on the fact that the notes_data returned by the elfcore module changes at each iteration, via (in procfs_corefile_thread_callback): args->note_data = procfs_do_thread_registers (args->obfd, ptid, args->note_data, args->note_size, args->stop_signal); (which calls elfcore_write_lwpstatus). But, while it happens most of the time, thanks to a call to realloc in elfcore_write_note (the function that actually appends the data at the end of the notes buffer),... buf = (char *) realloc (buf, *bufsiz + newspace); ... this is by no means guarantied. In fact, under the right circumstances, the buffer was grown twice without changing addresses. Unfortunately, the circumstances are very sensitive, thus making this bug very elusive. This patch fixes the problem by simply removing the assert. This means we're losing the assertion that there is at least one thread, but I think that's OK. If we still want to keep the assertion, we have the option of either checking the buffer size, or else adding a boolean flag in the context structure that we'd set to true as soon as we have a thread. gdb/ChangeLog: * procfs.c (procfs_make_note_section): Remove assertion and associated comment.

Change len's type to ULONGEST: remote_write_bytes_aux Hi, This patch changes the type of 'len' from ssize_t to ULONGEST. At the beginning Siddhesh Poyarekar proposed this patch [PATCH] Memory reads and writes should have size_t length https://sourceware.org/ml/gdb-patches/2012-05/msg01073.html to change type of 'len' to size_t. However, after Jan's review, we decide to change it to ssize_t, because callers of these functions may pass signed type to them. AFAICS, the target layer is a boundary. In one side, we pass size_t or ssize_t to target related APIs, and in the other side, the implementation side, we used LONGEST (ULONGEST in latest code) because of to_xfer_partial. Since remote_write_bytes_aux and remote_write_bytes belong to the implementation of remote target, we should use ULONGEST for len, IMO. Regression tested on x86_64-linux. Is it OK? gdb: 2014-01-24 Yao Qi <yao@codesourcery.com> * remote.c (remote_write_bytes_aux): Change type of 'len' to ULONGEST. Don't check 'len' is negative.

avoid python exception in FrameDecorator.py This fixes a bug in FrameDecorator.py. FrameVars seems to assume that Frame.block can return None if there is no block. However, it actually throws an exception. I saw this bug while developing a frame filter, but unfortunately I don't know how to reproduce it. It seems to me that the SAL tests in _is_limited_frame should exclude the bad cases; and in my attempts to write a test they do. Nevertheless I think the fix is reasonably obvious and ought to go in. 2014-01-23 Tom Tromey <tromey@redhat.com> PR python/16485: * python/lib/gdb/FrameDecorator.py: (FrameVars.fetch_frame_args): Handle exception from frame.block.

fix crash in frame filters apply_frame_filter calls ensure_python_env before computing the gdbarch to use.

gdb: xtensa: fix linux ptrace includes Currently, xtensa code using the Linux ptrace interface only include sys/ptrace.h. This file comes from the C library (glibc and uClibc, at least), and includes a declaration of the ptrace() functions, along with some cross architecture constants that are mostly copied from the file located at include/uapi/linux/ptrace.h in recent Linux kernels. For xtensa specific constants like PTRACE_GETXTREGS and PTRACE_SETXTREGS the asm/ptrace.h include from the Linux kernel UAPI is needed. The code in gdbserver xtensa specific part doesn't call ptrace() directly, so we can remove the unneeded sys/ptrace.h include.

rearrange struct value to save memory This patch rearranges struct value a tiny bit, moving the "regnum" field into a hole. This saves 8 bytes per value on a 64-bit machine, and 4 bytes per value on a 32 bit machine. I think it does not negatively affect readability or performance. Built and regtested on x86-64 Fedora 18. 2014-01-16 Tom Tromey <tromey@redhat.com> * value.c (struct value) <regnum>: Move earlier.

Fix gdb.trace/mi-traceframe-changed.exp on s390. The test fails on s390 with: -trace-find frame-number 0^M &"PC not available\n"^M ^done,found="1",tracepoint="1",traceframe="0",frame={level="-1",addr="<unavailable>",func="??",args=[]}^M (gdb) ^M FAIL: gdb.trace/mi-traceframe-changed.exp: tfile: -trace-find frame-number 0 tfile knows to infer the PC from the tracepoint's address if the PC wasn't collected (tfile_fetch_registers) but, that only works on targets whose PC register is a raw register, and on s390, the PC register is a pseudo register. But even if GDB doesn't know how to infer the value of PC, saying the current frame is level -1 is a bug: ^done,found="1",tracepoint="1",traceframe="0",frame={level="-1",addr="<unavailable>",func="??",args=[]}^M ^^^^^^^^^ '-1' is the level of the sentinel frame, which should never be visible. This is caused by the s390's heuristic unwinder accepting the frame (the fallback heuristic unwinders _always_ accept the frame), but then the unwind->this_id method throws that "PC not available\n" error. IOW, the s390's heuristic unwinder was never adjusted to handle unavailable register values gracefully, which can happen with e.g., a trimmed core file too. This is just the minimal necessary for <unavailable> frames, which at least gets us: (gdb) tfind Found trace frame 0, tracepoint 1 #0 <unavailable> in ?? () That is, frame #0 instead of -1. We could get better info out of "info frame" (this patch makes us show "outermost"), but this change would still be necessary. gdb/ 2014-01-16 Pedro Alves <palves@redhat.com> * s390-linux-tdep.c (s390_frame_unwind_cache): Swallow NOT_AVAILABLE_ERROR errors while parsing the prologue or reading the backchain.

btrace: change branch trace data structure The branch trace is represented as 3 vectors: - a block vector - a instruction vector - a function vector Each vector (except for the first) is computed from the one above. Change this into a graph where a node represents a sequence of instructions belonging to the same function and where we have three types of edges to connect the function segments: - control flow - same function (instance) - call stack This allows us to navigate in the branch trace. We will need this for "record goto" and reverse execution. This patch introduces the data structure and computes the control flow edges. It also introduces iterator structs to simplify iterating over the branch trace in control-flow order. It also fixes PR gdb/15240 since now recursive calls are handled correctly. Fix the test that got the number of expected fib instances and also the function numbers wrong. The current instruction had been part of the branch trace. This will look odd once we start support for reverse execution. Remove it. We still keep it in the trace itself to allow extending the branch trace more easily in the future. 2014-01-16 Markus Metzger <markus.t.metzger@intel.com> * btrace.h (struct btrace_func_link): New.

move the "main" data into the per-BFD object This adds the "main"-related data into the per-BFD. This is needed because once symbol sharing across objfiles is complete, computing the main name as a side effect of symbol reading will no longer work -- the symbols simply won't be re-read. After this change, set_main_name is only used by the main_name machinery itself, so this patch makes it static. 2014-01-15 Tom Tromey <tromey@redhat.com> * dbxread.c (process_one_symbol): Use set_objfile_main_name. * dwarf2read.c (read_partial_die): Use set_objfile_main_name. * objfiles.c (get_objfile_bfd_data): Initialize language_of_main.

Fix go32-nat.c build fallout from to_detach constification. The recent constification of to_detach missed updating the forward declaration of go32_detach, breaking the build: ../../src/gdb/go32-nat.c:387:1: error: conflicting types for 'go32_detach' ../../src/gdb/go32-nat.c:240:13: note: previous declaration of 'go32_detach' was here go32_detach is actually defined before it's ever used, making the forward declaration is unnecessary.

psymtab cleanup patch 3/3 This last patch removes "partial" from the names of expand_partial_symbol_names and map_partial_symbol_filenames. It also renames expand_partial_symbol_names to match the struct quick_symbol_functions "method" that it wraps: expand_symtabs_matching. This patch also adds two parameters to expand_symtabs_matching so that it can fully wrap the underlying quick_symbol_functions method. This makes it usable in more places.

Basically, these two functions do not belong in psymtab.c: expand_partial_symbol_names, map_partial_symbol_filenames, and "partial" does not belong in the function name. This first patch moves them to a better location. The second patch adds some typedefs for function parameters to quick_symbol_functions.expand_symtabs_matching. The third patch removes "partial" from the function names and uses them in more places. * psymtab.c (expand_partial_symbol_names): Delete, moved to symfile.c. (map_partial_symbol_filenames): Ditto. * psymtab.h (expand_partial_symbol_names): Delete, moved to symfile.h.

Fix "is a record target open" checks. RECORD_IS_USED and record_full_open look at current_target.to_stratum to determine whether a record target is in use. This is wrong because arch_stratum is greater than record_stratum, so if an arch_stratum target is pushed, RECORD_IS_USED and record_full_open will miss it. To fix this, we can use the existing find_record_target instead, which looks up for a record stratum target across the target stack. Since that means exporting find_record_target in record.h, RECORD_IS_USED ends up redundant, so the patch eliminates it. That exercise then reveals other issues: - adjust_pc_after_break is gating record_full_... calls based on RECORD_IS_USED. But, record_full_ calls shouldn't be made when recording with the record-btrace target. So this adds a new record_full_is_used predicate to be used in that spot. - record_full_open says "Process record target already running", even if the recording target is record-btrace ("process record" is the original complete name of the record-full target). record_btrace_open only says "The process is already being recorded." and does not suggest "record stop", like record-full does. The patch factors out and merges that error to a new record_preopen function that all record targets call in their open routine.

Have regdat.sh always rewrite the output register file The rules for generating the output register files look like: amd64.c : $(srcdir)/../regformats/i386/amd64.dat $(regdat_sh) $(SHELL) $(regdat_sh) $(srcdir)/../regformats/i386/amd64.dat amd64.c According to this rule, if regdat.sh is newer than amd64.c, then regdat.sh shall be invoked on amd64.dat. According to regdat.sh, if the script determines that the output file amd64.c has not changed, then it will not overwrite the existing output file. This means that a subsequent invocation of make will trigger the above rule again as regdat.sh will be perpetually newer than amd64.c. This then shows up in the make output like so: /bin/bash ./../regformats/regdat.sh ./../regformats/i386/amd64-linux.dat amd64-linux.c amd64-linux.c unchanged. /bin/bash ./../regformats/regdat.sh ./../regformats/i386/amd64-avx-linux.dat amd64-avx-linux.c amd64-avx-linux.c unchanged. ... To fix this pathological behavior, it suffices to have regdat.sh unconditionally rewrite the output register file. On my machine, which has a regdat.sh file that is newer than some of the input register files, this change speeds up every invocation of make under gdb/ by about 5 seconds.

Split i386_stap_parse_special_token into smaller functions This patch reorganizes code on gdb/i386-tdep.c's SystemTap SDT probe support functions. Before it, the code to parse special operands on x86 lived in a single, big function. This patch creates 2 new functions that makes the code more organized and removes a few indentation levels (which is always good IMO). I haven't modified anything logical in the functions, i.e., there's still one latent bug on i386_stap_parse_special_token_triplet now. I will soon post a patch to fix this, and to also improve the readability of the two new functions. 2014-01-12 Sergio Durigan Junior <sergiodj@redhat.com> * i386-tdep.c (i386_stap_parse_special_token_triplet): New function, with code from i386_stap_parse_special_token.

Handle the case of a remote target supporting target side commands, but not on software breakpoints. Although we can tell upfront whether a remote target supports target side commands, we can only tell whether the target supports that in combination with a given breakpoint kind (software, hardware, watchpoints, etc.) when we go and try to insert such a breakpoint kind the first time. It's not desirable to make remote_insert_breakpoint simply return -1 in this case, because if the breakpoint was set in a shared library, insert_bp_location will assume that the breakpoint insertion failed because the library wasn't mapped in. insert_bp_location already handles errors/exceptions thrown from the target_insert_xxx methods, exactly so the backend can tell the user the detailed reason the insertion of hw breakpoints failed. But, in the case of software breakpoints, it discards the detailed error message. So the patch makes insert_bp_location use the error's message for SW breakpoints too, and, introduces a NOT_SUPPORTED_ERROR error code so that insert_bp_location doesn't confuse the error for failure due to a shared library disappearing. The result is: (gdb) c Warning: Cannot insert breakpoint 2: Target doesn't support breakpoints that have target side commands. 2014-01-09 Pedro Alves <palves@redhat.com> Hui Zhu <hui@codesourcery.com> PR gdb/16101 * breakpoint.c (insert_bp_location): Rename hw_bp_err_string to bp_err_string.

[remote/gdbserver] Don't lose signals when reconnecting. Currently, when GDB connects in all-stop mode, GDBserver always responds to the status packet with a GDB_SIGNAL_TRAP, even if the program is actually stopped for some other signal. (gdb) tar rem ... ... (gdb) c Program received signal SIGUSR1, User defined signal 1. (gdb) disconnect (gdb) tar rem ... (gdb) c (Or a GDB crash instead of an explicit disconnect.) This results in the program losing that signal on that last continue, because gdb will tell the target to resume with no signal (to suppress the GDB_SIGNAL_TRAP, due to 'handle SISGTRAP nopass'), and that will actually suppress the real signal the program had stopped for (SIGUSR1). To fix that, I think we should make GDBserver report the real signal the thread had stopped for in response to the status packet: @item ? @cindex @samp{?} packet Indicate the reason the target halted. The reply is the same as for step and continue. But, that raises the question -- which thread are we reporting the status for? Due to how the RSP in all-stop works, we can only report one status. The status packet's response is a stop reply packet, so it includes the thread identifier, so it's not a problem packet-wise. However, GDBserver is currently always reporting the status for first thread in the thread list, even though that may well not be the thread that got the signal that caused the program to stop. So the next logical step would be to report the status for the last_ptid/last_status thread (the last event reported to gdb), if it's still around; and if not, fallback to some other thread. There's an issue on the GDB side with that, though... GDB currently always adds the thread reported in response to the status query as the first thread in its list. That means that if we start with e.g., (gdb) info threads 3 Thread 1003 ... * 2 Thread 1002 ... 1 Thread 1001 ... And reconnect: (gdb) disconnect (gdb) tar rem ... We end up with: (gdb) info threads 3 Thread 1003 ... 2 Thread 1001 ... * 1 Thread 1002 ... Not a real big issue, but it's reasonably fixable, by having GDB fetch/sync the thread list before fetching the status/'?', and then using the status to select the right thread as current on the GDB side. Holes in the thread numbers are squashed before/after reconnection (e.g., 2,3,5 becomes 1,2,3), but the order is preserved, which I think is both good, and good enough. However (yes, there's more...), the previous GDB that was connected might have had gdbserver running in non-stop mode, or could have left gdbserver doing disconnected tracing (which also forces non-stop), and if the new gdb/connection is in all-stop mode, we can end up with more than one thread with a signal to report back to gdb. As we can only report one thread/status (in the all-stop RSP variant; the non-stop variant doesn't have this issue), we get to do what we do at every other place we have this situation -- leave events we can't report right now as pending, so that the next resume picks them up. Note all this ammounts to a QoI change, within the existing framework. There's really no RSP change here. The only user visible change (other than that the signal is program is stopped at isn't lost / is passed to the program), is in "info program", that now can show the signal the program stopped for. Of course, the next resume will respect the pass/nopass setting for the signal in question. It'd be reasonable to have the initial connection tell the user the program was stopped with a signal, similar to when we load a core to debug, but I'm leaving that out for a future change. I think we'll need to either change how handle_inferior_event & co handle stop_soon, or maybe bypass them completely (like fork-child.c:startup_inferior) for that.

Ada: Fix missing call to pretty-printer for fields of records. Consider the following types: type Time_T is record Secs : Integer; end record; Before : Time_T := (Secs => 1384395743); In this example, we assume that type Time_T is the number of seconds since Epoch, and so added a Python pretty-printer, to print this type in a more human-friendly way. For instance: (gdb) print before $1 = Thu Nov 14 02:22:23 2013 (1384395743) However, we've noticed that things stop working when this type is embedded inside another record, and we try to print that record. For instance, with the following declarations: type Composite is record Id : Integer; T : Time_T; end record; Afternoon : Composite := (Id => 1, T => (Secs => 1384395865)); (gdb) print afternoon $2 = (id => 1, t => (secs => 1384395865)) We expected instead: (gdb) print afternoon $2 = (id => 1, t => Thu Nov 14 02:24:25 2013 (1384395865)) This patch fixes the problem by making sure that we try to print each field via a call to val_print, rather than calling ada_val_print directly. We need to go through val_print, as the val_print handles all language-independent features such as calling the pretty-printer, knowing that ada_val_print will get called eventually if actual Ada-specific printing is required (which should be the most common scenario). And because val_print takes the language as parameter, we enhanced the print_field_values and print_variant_part to also take a language. As a bonus, this allows us to remove a couple of references to current_language. gdb/ChangeLog: * ada-valprint.c (print_field_values): Add "language" parameter. Update calls to print_field_values and print_variant_part. Pass new parameter "language" in call to val_print instead of "current_language". Replace call to ada_val_print by call to val_print.

ada_print_floating: Remove use of statically sized buffer. ada_print_floating declares a char buffer with a size that we're hoping to always be large enough to hold any string representation of a float value. But that's not really necessary, and also forces us to create a small wrapper (ui_memcpy) to perform the extraction from a temporary stream into this buffer. This patches fixes both issues by relying on ui_file_xstrdup. This forces us to make a few adjustments that are minor in nature, as we now need to defer the cleanup to the end of the function. gdb/ChangeLog: * ada-valprint.c (ui_memcpy): Delete. (ada_print_floating): Update documentation. Add empty line between between function documentation and implementation. Delete variable "buffer". Use ui_file_xstrdup in place of ui_file_put.

Extract string-printing out of ada_val_print_array This patch creates a new function called "ada_val_print_string" whose code is directly extracted out of ada_val_print_array. The extracted code is then replaced by a call to this new function, followed by a "return". The return avoids the need for an "else" branch, with the associated block nesting. The latter is not really terrible in this case, but it seems more readable this way. gdb/ChangeLog: * ada-valprint.c (ada_val_print_string): New function, extracted from ada_val_print_array.

move ada_val_print_array down within other ada_val_print* functions This patch moves ada_val_print_array to group it with the other ada_val_print_* function which are being called by ada_val_print_1. Since this function is in the same situation, it is more logical to move it within that group. It also rationalizes the function's prototype to match the prototype of the other ada_val_print_* routines. gdb/ChangeLog: * ada-valprint.c (ada_val_print_array): Move implementation down.

rewrite ada_val_print_ref to reduce if/else block nesting depth The logic as currently implemented in this function was a little difficult to follow, due to the nested of if/else conditions, but most of the time, the "else" block was very simple. So this patch re-organizes the code to use fewer levels of nesting by using return statements, and writing the code as a sequence of "if something simple, then handle it and return" blocks. While touching this code, this patch changes the cryptic "???" printed when trying to print a reference pointing to an undefined type. This should only ever happen if the debugging information was corrupted or improperly read. But in case that happens, we now print "<ref to undefined type>" instead. This is more in line with how we print other conditions such as optimized out pieces, or synthetic pointers. gdb/ChangeLog: * ada-valprint.c (ada_val_print_ref): Rewrite by mostly re-organizing the code. Change the "???" message printed when target type is a TYPE_CODE_UNDEF into "<ref to undefined type>".

ada-valprint.c: Inline print_record inside ada_val_print_struct_union The function print_record is a fairly small and straightforward function which is only called from one location. So this patch inlines the code at the point of call. One small advantage is that the context of use of this patch has now become such that we can assume that TYPE is not a typedef, nor an enum. So thhe call to ada_check_typedef is unnecessary, and this patch removes it. gdb/ChangeLog: * ada-valprint.c (print_record): Delete, implementation inlined... (ada_val_print_struct_union): ... here.

Split ada_val_print_1 into smaller functions The idea of this patch is that it's hard to have a global view of ada_val_print_1 because its body spans over too many lines. Also, each individual "case" block within the giant "switch" can be hard to isolate if spanning over multiple pages as well. gdb/ChangeLog: * ada-valprint.c (ada_val_print_gnat_array): New function, extracted from ada_val_print_1; (ada_val_print_ptr, ada_val_print_num, ada_val_print_enum) (ada_val_print_flt, ada_val_print_struct_union) (ada_val_print_ref): Likewise.

Remove call to gdb_flush at end of ada_val_print_1 I am not sure why this function was called in the first place, but it disrupts the printing flow when in GDB/MI mode, ending the current console stream output, and starting a new one. It's not clear whether, with the code as currently written, the problem is actually visible or only latent. But, it becomes visible when we replace one of the "return" statements in the "switch" block just above by a "break" statement (this is something I'd like to do, and what made me realize the problem). With the gdb_flush call (after having replaced the "return" statement as explained above), we get: % gdb -q -i=mi ada_prg (gdb) print 1 &"print 1\n" !! -> ~"$1 = 1" !! -> ~"\n" ^done With the gdb_flush call removed, we now get the entire output into a single stream.

[python] Add gdb.Type.name attribute. Consider the following declarations: typedef long our_time_t; our_time_t current_time = 1384395743; The purpose of this patch is to allow the use of a pretty-printer for variables of type our_time_t. Normally, pretty-printing sniffers use the tag name in order to determine which, if any, pretty-printer should be used. But in the case above, the tag name is not set, since it does not apply to integral types. This patch extends the gdb.Type list of attributes to also include the name of the type, thus allowing the sniffer to match against that name. With that change, I was able to write a pretty-printer which displays our variable as follow: (gdb) print current_time $1 = Thu Nov 14 02:22:23 2013 (1384395743) gdb/ChangeLog: * python/py-type.c (typy_get_name): New function.
