Assuming the following declarations:
type Discriminants_Record (A : Integer; B : Boolean) is record
C : Float;
end record;
Z : Discriminants_Record := (A => 1, B => False, C => 2.0);
If variable Z is not used, and the compiler optimizes it out,
GDB would crash as follow:
(gdb) print Z
/[...]/gdb/valops.c:1121: internal-error: Unexpected lazy value type.
This is because the ada-lang module forgot to set the optimized_out
flag in the value returned by ada_evaluate_subexp during the value's
"fixing" process. Later on, when trying to print the resulting value,
GDB finds that the value is still lazily allocated, and thus tries to
fetch it. But this is not allowed for not_lval values, hence the internal
error.
gdb/ChangeLog:
* ada-lang.c (coerce_unspec_val_to_type): Make sure that
the optimized_out flag is preserved.

conversions permitted by the standard.
Replace -nw option with $INTERNAL_GDBFLAGS in "xgdb" tests to
avoid spurious results due to ~/.gdbinit.

$INTERNAL_GDBFLAGS in run command.

The problem is trying to unwind from a function where %ebp is NOT
used as the frame pointer, and the size of the frame changes over
the lifetime of that function.
For instance, trying to unwind past the GNAT runtime function
called system.tasking.rendezvous.timed_selective_wait on x86-linux,
one can get:
(gdb) bt
[...]
#3 0x0805364b in system.tasking.rendezvous.timed_selective_wait ()
#4 0xb7fe5068 in ?? ()
Backtrace stopped: previous frame inner to this frame (corrupt stack?)
Looking at the CFI, we find the following initial instructions...
> DW_CFA_def_cfa: %esp+4 (r4 ofs 4)
> DW_CFA_offset: %eip at cfa-4 (r8 = %eip)
... and the associated FDE:
> 00001be4 00000054 00001be8 FDE cie=00000000 pc=08053310..08053951
[...]
> DW_CFA_advance_loc: 8 to 080534ad
> DW_CFA_def_cfa_offset: 112
> DW_CFA_advance_loc2: 414 to 0805364b
> DW_CFA_def_cfa_offset: 108
[...]
The problem is that the DWARF frame unwinder executed the FDE until
the row for PC == 0x0805364b. But in reality, our program hasn't
executed the instruction at that address yet (it is the return address).
So GDB executed a little too much of the FDE, giving us the wrong
offset for the frame base, and thus the wrong address where %eip
got saved.
This patch fixes the problem by using a more correct PC as the bound
for executing the FDE.
gdb/ChangeLog:
* dwarf2-frame.c (dwarf2_frame_cache): Use
get_frame_address_in_block instead of get_frame_pc as
the bound for executing the frame's FDE.
gdb/testsuite/ChangeLog:
* gdb.ada/rdv_wait: New testcase.
(_initialize_values): Mention convenience functions in the help text
for "show convenience".
doc/
* gdb.texinfo (Convenience Vars): Update text for "show convenience"
to include functions.
testsuite/
* gdb.base/default.exp: Update expected output of "show convenience".
The command line completion has spoiled me. Thus the lack of completion with
the "handle" command annoys me. Patch!
This does a few things:
- adds a VEC_merge helper
- adds a generic signal completer
- adds a completion handler for the "handle" command
- sets the completion handler for the "signal" command
