[AArch64] Mark single precision pseudo registers unavailable if invalid

I noticed two failure in gdb.trace/mi-trace-frame-collected.exp:

FAIL: gdb.trace/mi-trace-frame-collected.exp: live:
  -trace-frame-collected (register)
FAIL: gdb.trace/mi-trace-frame-collected.exp: tfile:
  -trace-frame-collected (register)

In these cases, we are not collecting registers so the MI command
-trace-frame-collected should only give us the value of the PC.
However, it also gives us all of the single precision pseudo registers,
initialized with 0x0.

We can reproduce this error by simply issuing the
'maint print cooked-register' when no inferior is connected:

~~~

It turns out GDB does not check if S registers are valid before returning

8 years agoRemove CHECK_TYPEDEF, use check_typedef instead
Simon Marchi [Mon, 6 Jul 2015 20:05:06 +0000 (16:05 -0400)] 
Remove CHECK_TYPEDEF, use check_typedef instead

I think that the CHECK_TYPEDEF macro is not necessary, and even a bit
annoying.  It makes unclear the fact that the "type" variables gets
overwritten.  It has actually bitten me a few times.  I think the
following, explicit form, is better.

  type = check_typedef (type);

This patches changes all instances of CHECK_TYPEDEF for an equivalent
call to check_typedef.  The bulk of the change was done with this sed:

  sed -i 's/CHECK_TYPEDEF (\([^)]*\));/\1 = check_typedef (\1);/' <file>.c

The ChangeLog was generated using David Malcom's generate_changelog.py.
I manually fixed those places where it gets the wrong function name,
hopefully all of them.

The patch was built-tested, and I ran a few smoke tests.

[AArch64] Teach stub unwinder to terminate gracefully

The stub unwinder is used on AArch64 if the target's memory is not
readable at the current PC.  For example, the user could try to call at
an invalid address such as 0x0, as covered in the gdb.base/signull.exp
test case.  Many GDB ports use a similar unwinder to handle this case
too.

If we purposely kill the inferior before examining the trace then we get
the following issue:

~~~
...
(gdb) trace f
Tracepoint 3 at 0x7fb7fc28c0

This patch teaches the stub unwinder to report to the core frame code
with UNWIND_UNAVAILABLE when either the stack pointer of the return

[AArch64] Teach prologue unwinder to terminate gracefully

Without debugging information, we have the following issue when
examining a trace buffer:

~~~
...
(gdb) trace f
Tracepoint 3 at 0x7fb7fc28c0

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Found trace frame 0, tracepoint 3
#-1 0x0000007fb7fc28c0 in f () ...
^^^
~~~

The reason for this is that the target's stack pointer is unavailable
when examining the trace buffer.  What we are seeing is due to the
'tfind' command creating a sentinel frame and unwinding it.  If an
exception is thrown, we are left with the sentinel frame being displayed
at level #-1.  The exception is thrown when the prologue unwinder tries
to read the stack pointer to construct an ID for the frame.

This patch fixes this by making the prologue unwinder catch
NOT_AVAILABLE_ERROR exceptions when either registers or memory is
unreadable and report back to the frame core code with
UNWIND_UNAVAILABLE.

Delete program spaces directly when removing inferiors

When deleting an inferior, delete the associated program space as well
if it becomes unused. This replaces the "pruning" approach, with which
you could forget to call prune_program_spaces (as seen, with the
-remove-inferior command, see [1]).

This allows to remove the prune_program_spaces function. At the same
time, I was able to clean up the delete_inferior* family:

 - delete_inferior is unused
 - delete_inferior_silent is only used in monitor_close, but is replaced
   with discard_all_inferiors [2], so it becomes unused
 - All remaining calls to delete_inferior_1 are with silent=1, so the
   parameter is removed
 - delete_inferior_1 is renamed to delete_inferior

I renamed pspace_empty_p to program_space_empty_p. I prefer if the
"exported" functions have a more explicit and standard name.

Revert "Delete program spaces directly when removing inferiors"

Reverted, since it causes a build failure.  It turns out that
delete_inferior_silent wasn't actually unused.

This reverts commit 0560c645c02eba2828a053039dcfdf676cdd1d00.

Delete program spaces directly when removing inferiors

When deleting an inferior, delete the associated program space as well
if it becomes unused. This replaces the "pruning" approach, with which
you could forget to call prune_program_spaces (as seen, with the
-remove-inferior command, see [1]).

This allows to remove the prune_program_spaces function. At the same
time, I was able to clean up the delete_inferior* family.
delete_inferior_silent and delete_inferior were unused, which allowed
renaming delete_inferior_1 to delete_inferior. Also, since all calls to
it were with silent=1, I removed that parameter completely.

I renamed pspace_empty_p to program_space_empty_p. I prefer if the
"exported" functions have a more explicit and standard name.

Tested on Ubuntu 14.10.

This obsoletes my previous patch "Add call to prune_program_spaces in
mi_cmd_remove_inferior" [1].

compile: Warn for old GCC on cv-qualified self-reference

GDB could:

The bug was not in GDB but in the GCC part interfacing with GDB.

Alexandre Oliva has fixed it the right way:

After Alex upstreams the fix I can update the message to contain the specific
GCC release.

8 years agoPR18617 - Incorrect expression bytecode generated for narrowing conversions

PR18617 - Incorrect expression bytecode generated for narrowing conversions

The existing code preserves 'from' bits, which is incorrect.  E.g.

 (gdb) maint agent-eval (char)255L
 Scope: 0x4008d6
 Reg mask: 00
   0  const16 255
   3  ext 64
   5  end

'ext 64' should be 'ext 8'; this bytecode evaluates to 255 instead of
the correct result of -1.  The fix is simple.  I ran the entire test
suite on x86-64 and there were no new test failures.
