* gdb.python/py-xmethods.cc: Add global function call counters and
increment them in their respective functions. Remove "cout"
statements.
* gdb.python/py-xmethods.exp: Make tests check the global function
call counters instead of depending on inferior IO.
Using the test program gdb.base/foll-fork.c, with follow-fork-mode set to
"child" and detach-on-fork set to "off", stepping or running past the fork
call results in the child process running to completion, when it should
just finish the single step. In addition, the breakpoint is not removed
from the parent process, so if it is resumed it receives a SIGTRAP.
Cause:
No matter what the setting for detach-on-fork, when stepping past a fork,
the single-step breakpoint (step_resume_breakpoint) is not handled
correctly in the parent. The SR breakpoint is cloned for the child
process, but before the clone is associated with the child it is treated as
a duplicate of the original, associated wth the parent. This results in
the insertion state of the original SR breakpoint and the clone being
"swapped" by breakpoint.c:update_global_location_list, so that the clone is
marked as inserted.
In the case where the parent is not detached, the two breakpoints remain in
that state. The breakpoint is never inserted in the child, because
although the cloned SR breakpoint is associated with the child, it is
marked as inserted. When the child is resumed, it runs to completion. The
breakpoint is never removed from the parent, so that if it is resumed after
the child exits, it gets a SIGTRAP.
Here is the sequence of events:
1) handle_inferior_event: FORK event is recognized.
2) handle_inferior_event: detach_breakpoints removes all breakpoints
from the child.
3) follow_fork: the parent SR breakpoint is cloned. Part of this procedure
is to call update_global_location_list, which swaps the insertion state of
the original and cloned SR breakpoints as part of ensuring that duplicate
breakpoints are only inserted once. At this point the original SR
breakpoint is not marked as inserted, and the clone is. The breakpoint is
actually inserted in the parent but not the child.
4) follow_fork: the original breakpoint is deleted by calling
delete_step_resume_breakpoint. Since the original is not marked as
inserted, the actual breakpoint remains in the parent process.
update_global_location_list is called again as part of the deletion. The
clone is still associated with the parent, but since it is marked as
enabled and inserted, the breakpoint is left in the parent.
5) follow_fork: if detach-on-fork is 'on', the actual breakpoint will be
removed from the parent in target_detach, based on the cloned breakpoint
still associated with the parent. Then the clone is no longer marked as
inserted. In follow_inferior_reset_breakpoints the clone is associated
with the child, and can be inserted.
If detach-on-fork is 'off', the actual breakpoint in the parent is never
removed (although the breakpoint had been deleted from the list). Since
the clone continues to be marked 'inserted', the SR breakpoint is never
inserted in the child.
Fix:
Set the cloned breakpoint as disabled from the moment it is created. This
is done by modifying clone_momentary_breakpoint to take an additional
argument, LOC_ENABLED, which is used as the value of the
bp_location->enabled member. The clone must be disabled at that point
because clone_momentary_breakpoint calls update_global_location_list, which
will swap treat the clone as a duplicate of the original breakpoint if it
is enabled.
All the calls to clone_momentary_breakpoint had to be modified to pass '1'
or '0'. I looked at implementing an enum for the enabled member, but
concluded that readability would suffer because there are so many places it
is used as a boolean, e.g. "if (bl->enabled)".
In follow_inferior_reset_breakpoints the clone is set to enabled once it
has been associated with the child process. With this, the bp_location
'inserted' member is maintained correctly throughout the follow-fork
procedure and the behavior is as expected.
The same treatment is given to the exception_resume_breakpoint when
following a fork.
Testing:
Ran 'make check' on Linux x64.
Along with the fix above, the coverage of the follow-fork test
gdb.base/foll-fork.exp was expanded to:
1) cover all the combinations of values for
follow-fork-mode and detach-on-fork
2) make sure that both user breakpoints and
single-step breakpoints are propagated
correctly to the child
3) check that the inferior list has the
expected contents after following the fork.
4) check that unfollowed, undetached inferiors
can be resumed.

skip_type_update_when_not_use_rtti_test) the testcase assumes an
uninitialized object has a specific type. In particular, 'ptr' and
's'.
In reality the compiler is free to do what it wants with that
uninitialized variable, even initialize it beforehand with the future
assignment's value. This is exactly what happens on some targets.
ptr should have type 'Base *', but it really has type 'Derived *'
because it is already initialized (earlier) by the compiler. The same
thing happens to 's'.
The following patch addresses this by explicitly initializing those
variables so the compiler doesn't optimize their assignments and GDB
can print their correct values.

If an MI client creates a varobj and attempts to update the root
/before/ the inferior is started, gdb will throw an internal error:
(gdb)
-var-create * - batch_flag

(gdb)
-var-update var1

~"../../src/gdb/thread.c:628: internal-error: is_thread_state: Assertion `tp' failed.\nA problem internal to GDB has been detected,\nfurther debugging may prove unreliable.\nQuit this debugging session? "
~"(y or n) "
The function that handles the varobj update in the failing case,
mi_cmd_var_udpate_iter, checks if the thread/inferior is stopped before
attempting to update the varobj. It calls is_stopped (inferior_ptid)
which calls is_thread_state:
tp = find_thread_ptid (ptid);
gdb_assert (tp);
When there is no inferior, ptid is null_ptid, and find_thread_ptid (null_ptid)
returns NULL and the assertion is triggered.
This patch changes mi_cmd_var_update_iter to behave the same way
"-var-update var1" does: by calling the thread "stopped" if
there is no inferior (and thereby calling varobj_update_one).

Turns out there's a difference between loading the program with "gdb
PROGRAM", vs loading it with "(gdb) file PROGRAM". The latter results
in the objfile ending up with OBJF_USERLOADED set, while not with the
former. (That difference seems bogus, but still that's not the point
of this patch. We can revisit that afterwards.)
The new code that suppresses breakpoint removal errors for
add-symbol-file objects ends up being too greedy:
/* In some cases, we might not be able to remove a breakpoint in
a shared library that has already been removed, but we have
not yet processed the shlib unload event. Similarly for an
unloaded add-symbol-file object - the user might not yet have
had the chance to remove-symbol-file it. shlib_disabled will
be set if the library/object has already been removed, but
the breakpoint hasn't been uninserted yet, e.g., after
"nosharedlibrary" or "remove-symbol-file" with breakpoints
always-inserted mode. */
if (val
&& (bl->loc_type == bp_loc_software_breakpoint
&& (bl->shlib_disabled
|| solib_name_from_address (bl->pspace, bl->address)
|| userloaded_objfile_contains_address_p (bl->pspace,
bl->address))))
val = 0;
as it turns out that OBJF_USERLOADED can be set for objfiles loaded by
some other means not add-symbol-file. In this case, symbol-file (or
"file", which is really just "exec-file"+"symbol-file").
Recall that add-symbol-file is documented as:
(gdb) help add-symbol-file
Load symbols from FILE, assuming FILE has been dynamically loaded.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
And it's the "dynamically loaded" aspect that the breakpoint.c code
cares about. So make add-symbol-file set OBJF_SHARED on its objfiles
too, and tweak the breakpoint.c code to look for OBJF_SHARED instead
of OBJF_USERLOADED.
This restores back the missing breakpoint removal warning when we let
sss-bp-on-user-bp-2.exp run on native GNU/Linux
(https://sourceware.org/ml/gdb-patches/2014-06/msg00335.html):

I say "restores" because this was GDB's behavior in 7.7 and earlier.
And, likewise, "file" with no arguments only started turning
breakpoints set in the main executable to "<pending>" with the
remote-symbol-file patch (63644780). The old behavior is now
restored, and we break-unload-file.exp test now exercizes both "gdb;
file PROGRAM" and "gdb PROGRAM".

This is to fix unitialised memory access when printing listings.
Many targets don't initialise parts of insn frags or data frags that
have fixups, relying on md_apply_fix to finalise the frag. Which is
fine normally, but means we need to run write_object_file after

* config/tc-arm.c (s_arm_elf_cons): Initialise after frag_more.
(md_apply_fix): Delete now unnecessary zeroing for BFD_RELOC_ARM_GOT*
and BFD_RELOC_ARM_TLS* relocs. Simplify BFD_RELOC_8 case.
