Mostly trivial enum fixes This is a patch I extracted from Pedro's C++ branch. It contains the most trivial enum fixes, where an integer type/value was used instead of the appropriate enum type/value. It fixes many C++ errors, since in C++ you can't mix integers and enums implicitely. Regardless of the C++ conversion, I think this is a good cleanup to make use of the appropriate enum types.

#include "breakpoint.h" /* For enum bptype. */
/* This include file defines the interface between the main part
of the debugger, and the part which is target-specific, or
specific to the communications interface between us and the
target.
A TARGET is an interface between the debugger and a particular
kind of file or process. Targets can be STACKED in STRATA,
so that more than one target can potentially respond to a request.
In particular, memory accesses will walk down the stack of targets
until they find a target that is interested in handling that particular
address. STRATA are artificial boundaries on the stack, within
which particular kinds of targets live. Strata exist so that
people don't get confused by pushing e.g. a process target and then
a file target, and wondering why they can't see the current values
of variables any more (the file target is handling them and they
never get to the process target). So when you push a file target,
it goes into the file stratum, which is always below the process
stratum. */

Mostly trivial enum fixes This is a patch I extracted from Pedro's C++ branch. It contains the most trivial enum fixes, where an integer type/value was used instead of the appropriate enum type/value. It fixes many C++ errors, since in C++ you can't mix integers and enums implicitely. Regardless of the C++ conversion, I think this is a good cleanup to make use of the appropriate enum types. Regression-tested on native x86_64. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_linux_can_use_hw_breakpoint): Use enum type or value instead of integer. (aarch64_linux_insert_watchpoint): Likewise.

TARGET_OBJECT_STATIC_TRACE_DATA,
[ia64-hpux] unwinding bsp value from system call This fixes unwinding from a thread that is stopped inside a system call. This can be seen when switching to a thread that is stopped doing a pthread_cond_wait, for instance... The comments inside the code should explain what is happening in our case (the HP-UX exception in the case of system calls): Under certain circumstances (program stopped inside syscall), the offset to apply to the current BSP in order to compute the previous BSP is not the usual CFM & 0x7f. We parts in this patch: 1. Figuring out that we are stopped inside a syscal: This requires a TT_LWP_RUREGS ttrace call, which is not directly possible from ia64-tdep.c. So use defined a new TARGET_OBJECT_HPUX_UREGS object to request it from the -nat side. 2. Add a gdbarch_tdep method that allows us to change the default behavior on ia64-hpux, permitting us to have a different "size of register frame" in that one particular case. gdb/ChangeLog: * target.h (enum target_object): Add TARGET_OBJECT_HPUX_UREGS. * ia64-tdep.h (struct frame_info): forward declaration.

TARGET_OBJECT_HPUX_UREGS,
[ia64-hpux] inferior function call support We have two stacks to deal with on ia64, when making a function call. The first is the usual stack frame, and the second is the register stack frame. On ia64-linux, the register frame is setup by adjusting the BSP register. Unfortunately for us, the HP-UX kernel does not allow the debugger to change the value of the BSP. To work around that limitation, the method I am using here is to push some assembly code on the stack. This assembly code contains, among other things, a call to the alloc insn, which sets up our frame for us. An extensive comment in ia64-hpux-tdep.c explains the entire procedure. Despite this approach, most of the code in ia64-tdep.c which sets up the function call is still applicable - and only a few things need to be done differently: For instance, instead of changing the BSP, we do nothing. We store the parameters at a different location, etc. So this patch also adjusts the inf-call code in ia64-tdep.c to make it a little more extensible: I create a new ia64_infcall_ops structure which allows an ABI to define how the few things that need to be differentiated. Another element that turned out to be necessary but is more of a detail is that the computation of the linkage pointer needs to be handled specially for symbols inside shared libraries. This is especially visible when calling malloc, which happens everytime memory needs to be allocated in inferior memory... The special treatment included again the necessity to use some routines only available on the host. So another target object TARGET_OBJECT_HPUX_SOLIB_GOT was created for that purpose. gdb/ChangeLog: * ia64-tdep.h (struct regcache): Forward declare. (struct ia64_infcall_ops): New struct type.

record btrace: add configuration struct Add a struct to describe the branch trace configuration and use it for enabling branch tracing. The user will be able to set configuration fields for each tracing format to be used for new threads. The actual configuration that is active for a given thread will be shown in the "info record" command. At the moment, the configuration struct only contains a format field that is set to the only available format. The format is the only configuration option that can not be set via set commands.

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.

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".

Presently, only the value machinery knows to handle unavailable memory. We need to push the awareness down to the target_xfer layer, making it return a finer grained error indication. We can only return a generic -1 nowadays, which leaves the upper layers with no clue on why the xfer failed. Use target_xfer_partial directly, rather than propagating the error through target_read_memory so as to get a better address to display in the error message. (target_read_memory & friends build on top of target_read (thus the target_xfer machinery), but turn all errors to EIO, an errno value. I think this is a mistake, and we'd better convert all these to return a target_xfer_error too, but that can be done separately. I looked around a bit over memory_error calls, and the need to handle random errno values, other than the EIOs gdb itself hardcodes, probably comes (only) from deprecated_xfer_memory, which uses errno for error indication, but I didn't look exhaustively. We should really get rid of deprecated_xfer_memory and of passing down errno values as error indication in target_read & friends methods). Tested on x86_64 Fedora 17, native and gdbserver.

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.

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.

Stop using errno values around target_xfer interfaces and memory errors. target_read_memory & friends build on top of target_read (thus on top of the target_xfer machinery), but turn all errors to EIO, an errno value. I think we'd better convert all these to return a target_xfer_error too, like target_xfer_partial in a previous patch. The patch starts by doing that. (The patch does not add a enum target_xfer_error value for '0'/no error, and likewise does not change the return type of several of these functions to enum target_xfer_error, because different functions return '0' with different semantics.) I audited the tree for memory_error calls, EIO checks, places where GDB hardcodes 'errno = EIO', and also for strerror calls. What I found is that nowadays there's really no need to handle random errno values, other than the EIOs gdb itself hardcodes. No doubt errno values would appear in common code back in the day when target_xfer_memory was the main interface to access memory, but nowadays, any errno value that deprecated interface could return is just absorved by default_xfer_partial: else if (xfered == 0 && errno == 0) /* "deprecated_xfer_memory" uses 0, cross checked against ERRNO as one indication of an error. */ return 0; else return -1; There are two places in the code that check for EIO and print "out of bounds", and defer to strerror for other errors. That's c-lang.c:c_get_string, and valprint.c.:val_print_string. AFAICT, the strerror branch can never be reached nowadays, as the only error possible to get at those points is EIO, given that it's GDB itself that set that errno value (in target_read_memory, etc.). breakpoint.c:insert_bp_location always prints the error val as if an errno, returned by target_insert_breakpoint, with strerr. Now the error here is either always EIO for mem-break.c targets (again hardcoded by the target_read_memory/target_write_memory functions), so this always prints "Input/output error" or similar (depending on host), or, for remote targets (and probably others), this gem: Error accessing memory address 0x80200400: Unknown error -1. This patch makes these 3 places print the exact same error memory_error prints. This changes output, but I think this is better, for making memory error output consistent with other commands, and, it means we have a central place to tweak for memory errors. E.g., this changes: Cannot insert breakpoint 1. Error accessing memory address 0x5fc660: Input/output error. to: Cannot insert breakpoint 1. Cannot access memory at address 0x5fc660 Which I find pretty much acceptable. Surprisingly, only py-prettyprint.exp had a regression, for needing an adjustment. I also grepped the testsuite for the old errors, and found no other hits. Now that errno values aren't used anywhere in any of these memory access related routines, I made memory_error itself take a target_xfer_error instead of an errno. The new target_xfer_memory_error function added recently is no longer necessary, and is thus removed.

Use target_xfer_partial directly, rather than propagating the error through target_read_memory so as to get a better address to display in the error message.

Presently, only the value machinery knows to handle unavailable memory. We need to push the awareness down to the target_xfer layer, making it return a finer grained error indication. We can only return a generic -1 nowadays, which leaves the upper layers with no clue on why the xfer failed. Use target_xfer_partial directly, rather than propagating the error through target_read_memory so as to get a better address to display in the error message. (target_read_memory & friends build on top of target_read (thus the target_xfer machinery), but turn all errors to EIO, an errno value. I think this is a mistake, and we'd better convert all these to return a target_xfer_error too, but that can be done separately. I looked around a bit over memory_error calls, and the need to handle random errno values, other than the EIOs gdb itself hardcodes, probably comes (only) from deprecated_xfer_memory, which uses errno for error indication, but I didn't look exhaustively. We should really get rid of deprecated_xfer_memory and of passing down errno values as error indication in target_read & friends methods). Tested on x86_64 Fedora 17, native and gdbserver. Fixes the test in the PR, which will be added to the testsuite later. gdb/ 2013-08-22 Pedro Alves <palves@redhat.com> PR gdb/15871 * corefile.c (target_xfer_memory_error): New function.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

does nothing. This is only valid if the method return type is
'void'.
2. TARGET_DEFAULT_NORETURN. The argument is a function call, like
'tcomplain ()'. The base method simply makes this call, which is
assumed not to return.

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.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

Teach GDB about targets that can tell whether a trap is a breakpoint event The moribund locations heuristics are problematic. This patch teaches GDB about targets that can reliably tell whether a trap was caused by a software or hardware breakpoint, and thus don't need moribund locations, thus bypassing all the problems that mechanism has. The non-stop-fair-events.exp test is frequently failing currently. E.g., see https://sourceware.org/ml/gdb-testers/2015-q1/msg03148.html. The root cause is a fundamental problem with moribund locations. For example, the stepped_breakpoint logic added by af48d08f breaks in this case (which is what happens with that test): - Step thread A, no breakpoint is set at PC. - The kernel doesn't schedule thread A yet. - Insert breakpoint at A's PC, for some reason (e.g., a step-resume breakpoint for thread B). - Kernel finally schedules thread A. - thread A's stepped_breakpoint flag is not set, even though it now stepped a breakpoint instruction. - adjust_pc_after_break gets the PC wrong, because PC == PREV_PC, but stepped_breakpoint is not set. We needed the stepped_breakpoint logic to workaround moribund locations, because otherwise adjust_pc_after_break could apply an adjustment when it shouldn't just because there _used_ to be a breakpoint at PC (a moribund breakpoint location). For example, on x86, that's wrong if the thread really hasn't executed an int3, but instead executed some other 1-byte long instruction. Getting the PC adjustment wrong of course leads to the inferior executing the wrong instruction. Other problems with moribund locations are: - if a true SIGTRAP happens to be raised when the program is executing the PC that used to have a breakpoint, GDB will assume that is a trap for a breakpoint that has recently been removed, and thus we miss reporting the random signal to the user. - to minimize that, we get rid of moribund location after a while. That while is defined as just a certain number of events being processed. That number of events sometimes passes by before a delayed breakpoint is processed, and GDB confuses the trap for a random signal, thus reporting the random trap. Once the user resumes the thread, the program crashes because the PC was not adjusted... The fix for all this is to bite the bullet and get rid of heuristics and instead rely on the target knowing accurately what caused the SIGTRAP. The target/kernel/stub is in the best position to know what that, because it can e.g. consult priviledged CPU flags GDB has no access to, or by knowing which exception vector entry was called when the instruction trapped, etc. Most debug APIs I've seen to date report breakpoint hits as a distinct event in some fashion. For example, on the Linux kernel, whether a breakpoint was executed is exposed to userspace in the si_code field of the SIGTRAP's siginfo. On Windows, the debug API reports a EXCEPTION_BREAKPOINT exception code. We needed to keep around deleted breakpoints in an on-the-side list (the moribund locations) for two main reasons: - Know that a SIGTRAP actually is a delayed event for a hit of a breakpoint that was removed before the event was processed, and thus should not be reported as a random signal. - So we still do the decr_pc_after_break adjustment in that case, so that the thread is resumed at the correct address. In the new model, if GDB processes an event the target tells is a breakpoint trap, and GDB doesn't find the corresponding breakpoint in its breakpoint tables, it means that event is a delayed event for a breakpoint that has since been removed, and thus the event should be ignored. For the decr_pc_after_after issue, it ends up being much simpler that on targets that can reliably tell whether a breakpoint trapped, for the breakpoint trap to present the PC already adjusted. Proper multi-threading support already implies that targets needs to be doing decr_pc_after_break adjustment themselves, otherwise for example, in all-stop if two threads hit a breakpoint simultaneously, and the user does "info threads", he'll see the non-event thread that hit the breakpoint stopped at the wrong PC. This way (target adjusts) also ends up eliminating the need for some awkward re-incrementing of the PC in the record-full and Linux targets that we do today, and the need for the target_decr_pc_after_break hook. If the target always adjusts, then there's a case where GDB needs to re-increment the PC. Say, on x86, an "int3" instruction that was explicitly written in the program traps. In this case, GDB should report a random SIGTRAP signal to the user, with the PC pointing at the instruction past the int3, just like if GDB was not debugging the program. The user may well decide to pass the SIGTRAP to the program because the program being debugged has a SIGTRAP handler that handles its own breakpoints, and expects the PC to be unadjusted.

Mostly trivial enum fixes This is a patch I extracted from Pedro's C++ branch. It contains the most trivial enum fixes, where an integer type/value was used instead of the appropriate enum type/value. It fixes many C++ errors, since in C++ you can't mix integers and enums implicitely. Regardless of the C++ conversion, I think this is a good cleanup to make use of the appropriate enum types.

Mostly trivial enum fixes This is a patch I extracted from Pedro's C++ branch. It contains the most trivial enum fixes, where an integer type/value was used instead of the appropriate enum type/value. It fixes many C++ errors, since in C++ you can't mix integers and enums implicitely. Regardless of the C++ conversion, I think this is a good cleanup to make use of the appropriate enum types.

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 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.

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.

auto-generate most target debug methods The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier.

Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet. It simply exports prune_threads, and makes all implementations of target_update_thread_list call that.

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.

/* This method must be implemented in some situations. See the

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.

int (*to_can_async_p) (struct target_ops *)
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.

Since both common code and target backends need to be able to put the target in and out of target async mode at any given time, there's really no way that a different callback could be passed.

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.

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".

smaller than LEN does not indicate the end of the object, only
the end of the transfer; higher level code should continue
transferring if desired. This is handled in target.c.
The interface does not support a "retry" mechanism. Instead it
assumes that at least one byte will be transfered on each
successful call.
NOTE: cagney/2003-10-17: The current interface can lead to
fragmented transfers. Lower target levels should not implement
hacks, such as enlarging the transfer, in an attempt to
compensate for this. Instead, the target stack should be
extended so that it implements supply/collect methods and a
look-aside object cache. With that available, the lowest
target can safely and freely "push" data up the stack.
See target_read and target_write for more information. One,
and only one, of readbuf or writebuf must be non-NULL. */

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.

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.

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 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.

constify to_detach This patch constifies the target_ops method to_detach. This is a small cleanup, but also, I think, a bug-prevention fix, since gdb already acts as if the "args" argument here was const. In particular, top.c:quit_force calls kill_or_detach via iterate_over_inferiors. kill_or_detach calls target_detach, passing the same argument each time. So, if one of these methods was not const-correct, then kill_or_detach would change its behavior in a strange way. I could not build every target I modified in this patch. I've inspected them all by hand, though. Many targets do not use the "args" parameter; a couple pass it to atoi; and a few pass it on to the to_detach method of the target beneath. The only code that required a real change was in linux-nat.c, and that only needed the introduction of a temporary variable for const-correctness. 2013-11-08 Tom Tromey <tromey@redhat.com> * aix-thread.c (aix_thread_detach): Update. * corelow.c (core_detach): Update. * darwin-nat.c (darwin_detach): Update. * dec-thread.c (dec_thread_detach): Update. * gnu-nat.c (gnu_detach): Update. * go32-nat.c (go32_detach): Update. * inf-ptrace.c (inf_ptrace_detach): Update. * inf-ttrace.c (inf_ttrace_detach): Update. * linux-fork.c (linux_fork_detach): Update. * linux-fork.h (linux_fork_detach): Update. * linux-nat.c (linux_nat_detach): Update.

/* Insert a breakpoint at address BP_TGT->placed_address in
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.

/* Remove a breakpoint at address BP_TGT->placed_address in the target
Stop using errno values around target_xfer interfaces and memory errors. target_read_memory & friends build on top of target_read (thus on top of the target_xfer machinery), but turn all errors to EIO, an errno value. I think we'd better convert all these to return a target_xfer_error too, like target_xfer_partial in a previous patch. The patch starts by doing that. (The patch does not add a enum target_xfer_error value for '0'/no error, and likewise does not change the return type of several of these functions to enum target_xfer_error, because different functions return '0' with different semantics.) I audited the tree for memory_error calls, EIO checks, places where GDB hardcodes 'errno = EIO', and also for strerror calls. What I found is that nowadays there's really no need to handle random errno values, other than the EIOs gdb itself hardcodes. No doubt errno values would appear in common code back in the day when target_xfer_memory was the main interface to access memory, but nowadays, any errno value that deprecated interface could return is just absorved by default_xfer_partial: else if (xfered == 0 && errno == 0) /* "deprecated_xfer_memory" uses 0, cross checked against ERRNO as one indication of an error. */ return 0; else return -1; There are two places in the code that check for EIO and print "out of bounds", and defer to strerror for other errors. That's c-lang.c:c_get_string, and valprint.c.:val_print_string. AFAICT, the strerror branch can never be reached nowadays, as the only error possible to get at those points is EIO, given that it's GDB itself that set that errno value (in target_read_memory, etc.). breakpoint.c:insert_bp_location always prints the error val as if an errno, returned by target_insert_breakpoint, with strerr. Now the error here is either always EIO for mem-break.c targets (again hardcoded by the target_read_memory/target_write_memory functions), so this always prints "Input/output error" or similar (depending on host), or, for remote targets (and probably others), this gem: Error accessing memory address 0x80200400: Unknown error -1. This patch makes these 3 places print the exact same error memory_error prints. This changes output, but I think this is better, for making memory error output consistent with other commands, and, it means we have a central place to tweak for memory errors. E.g., this changes: Cannot insert breakpoint 1. Error accessing memory address 0x5fc660: Input/output error. to: Cannot insert breakpoint 1. Cannot access memory at address 0x5fc660 Which I find pretty much acceptable. Surprisingly, only py-prettyprint.exp had a regression, for needing an adjustment. I also grepped the testsuite for the old errors, and found no other hits. Now that errno values aren't used anywhere in any of these memory access related routines, I made memory_error itself take a target_xfer_error instead of an errno. The new target_xfer_memory_error function added recently is no longer necessary, and is thus removed.

Make common code handle target_terminal_* idempotency I found a place that should be giving back the terminal to the target, but only if the target was already owning it. So I need to add a getter for who owns the terminal. The trouble is that several places/target have their own globals to track this state: - inflow.c:terminal_is_ours - remote.c:remote_async_terminal_ours_p - linux-nat.c:async_terminal_is_ours - go32-nat.c:terminal_is_ours While one might think of adding a new target_ops method to query this, conceptually, this state isn't really part of a particular target_ops. Considering multi-target, the core shouldn't have to ask all targets to know whether it's GDB that owns the terminal. There's only one GDB (or rather, only one top level interpreter). So what this comment does is add a new global that is tracked by the core instead. A subsequent pass may later remove the other globals.

extern int target_thread_alive (ptid_t ptid);
Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet. It simply exports prune_threads, and makes all implementations of target_update_thread_list call that.

/* Sync the target's threads with GDB's thread list. */
1999-05-05 14:45:51 +00:00
Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet. It simply exports prune_threads, and makes all implementations of target_update_thread_list call that. It's meant to be a no-op. gdb/ 2014-10-15 Pedro Alves <palves@redhat.com> * ada-tasks.c (print_ada_task_info, task_command_1): Adjust. * bsd-uthread.c (bsd_uthread_find_new_threads): Rename to ...

/* Does the target have execution? Can we make it jump (through
hoops), or pop its stack a few times? This means that the current
target is currently executing; for some targets, that's the same as
whether or not the target is capable of execution, but there are
also targets which can be current while not executing. In that
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.

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.

Simplify target_async hook interface All callers of target_async pass it the same callback (inferior_event_handler). Since both common code and target backends need to be able to put the target in and out of target async mode at any given time, there's really no way that a different callback could be passed. This commit simplifies things, and removes the indirection altogether. Bonus: with this, gdb's target_async method ends up with the same signature as gdbserver's.

Teach GDB about targets that can tell whether a trap is a breakpoint event The moribund locations heuristics are problematic. This patch teaches GDB about targets that can reliably tell whether a trap was caused by a software or hardware breakpoint, and thus don't need moribund locations, thus bypassing all the problems that mechanism has. The non-stop-fair-events.exp test is frequently failing currently. E.g., see https://sourceware.org/ml/gdb-testers/2015-q1/msg03148.html. The root cause is a fundamental problem with moribund locations. For example, the stepped_breakpoint logic added by af48d08f breaks in this case (which is what happens with that test): - Step thread A, no breakpoint is set at PC. - The kernel doesn't schedule thread A yet. - Insert breakpoint at A's PC, for some reason (e.g., a step-resume breakpoint for thread B). - Kernel finally schedules thread A. - thread A's stepped_breakpoint flag is not set, even though it now stepped a breakpoint instruction. - adjust_pc_after_break gets the PC wrong, because PC == PREV_PC, but stepped_breakpoint is not set. We needed the stepped_breakpoint logic to workaround moribund locations, because otherwise adjust_pc_after_break could apply an adjustment when it shouldn't just because there _used_ to be a breakpoint at PC (a moribund breakpoint location). For example, on x86, that's wrong if the thread really hasn't executed an int3, but instead executed some other 1-byte long instruction. Getting the PC adjustment wrong of course leads to the inferior executing the wrong instruction. Other problems with moribund locations are: - if a true SIGTRAP happens to be raised when the program is executing the PC that used to have a breakpoint, GDB will assume that is a trap for a breakpoint that has recently been removed, and thus we miss reporting the random signal to the user. - to minimize that, we get rid of moribund location after a while. That while is defined as just a certain number of events being processed. That number of events sometimes passes by before a delayed breakpoint is processed, and GDB confuses the trap for a random signal, thus reporting the random trap. Once the user resumes the thread, the program crashes because the PC was not adjusted... The fix for all this is to bite the bullet and get rid of heuristics and instead rely on the target knowing accurately what caused the SIGTRAP. The target/kernel/stub is in the best position to know what that, because it can e.g. consult priviledged CPU flags GDB has no access to, or by knowing which exception vector entry was called when the instruction trapped, etc. Most debug APIs I've seen to date report breakpoint hits as a distinct event in some fashion. For example, on the Linux kernel, whether a breakpoint was executed is exposed to userspace in the si_code field of the SIGTRAP's siginfo. On Windows, the debug API reports a EXCEPTION_BREAKPOINT exception code. We needed to keep around deleted breakpoints in an on-the-side list (the moribund locations) for two main reasons: - Know that a SIGTRAP actually is a delayed event for a hit of a breakpoint that was removed before the event was processed, and thus should not be reported as a random signal. - So we still do the decr_pc_after_break adjustment in that case, so that the thread is resumed at the correct address. In the new model, if GDB processes an event the target tells is a breakpoint trap, and GDB doesn't find the corresponding breakpoint in its breakpoint tables, it means that event is a delayed event for a breakpoint that has since been removed, and thus the event should be ignored. For the decr_pc_after_after issue, it ends up being much simpler that on targets that can reliably tell whether a breakpoint trapped, for the breakpoint trap to present the PC already adjusted. Proper multi-threading support already implies that targets needs to be doing decr_pc_after_break adjustment themselves, otherwise for example, in all-stop if two threads hit a breakpoint simultaneously, and the user does "info threads", he'll see the non-event thread that hit the breakpoint stopped at the wrong PC. This way (target adjusts) also ends up eliminating the need for some awkward re-incrementing of the PC in the record-full and Linux targets that we do today, and the need for the target_decr_pc_after_break hook. If the target always adjusts, then there's a case where GDB needs to re-increment the PC. Say, on x86, an "int3" instruction that was explicitly written in the program traps. In this case, GDB should report a random SIGTRAP signal to the user, with the PC pointing at the instruction past the int3, just like if GDB was not debugging the program. The user may well decide to pass the SIGTRAP to the program because the program being debugged has a SIGTRAP handler that handles its own breakpoints, and expects the PC to be unadjusted.

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.

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.

remove pop_target This patch fixes the target double-close problem (PR remote/15266), and in the process removes pop_target entire (PR remote/15256). The first issue is that pop_target calls target_close. However, it then calls unpush_target, which also calls target_close. This means targets must be able to be closed twice. Not only is this strange, but it also directly contradicts the contract of to_xclose targets. (We currently have just a single such target, and it is never pushed; but I plan to add more, and so this latent bug is triggered.) The second issue is that it seems to me that calling pop_target is often unsafe. This is what cropped up in 15256, where the remote target assumed that it could pop_target -- but there was another target higher on the stack, leading to confusion. But, it is always just as easy to call unpush_target as it is to call pop_target; and it is also safer. So, removing pop_target seemed like an improvement. Finally, this adds an assertion to target_close to ensure that no currently-pushed target can be closed. Built and regtested on x86-64 Fedora 18; both natively and using the native-gdbserver board file.

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.
