Fix typo
Hi,
"It's" should be "Its". This patch is to fix it. Committed as
obvious.

* varobj.c (varobj_get_type): Fix typo.

Fix int() builtin with range type gdb.Value objects.
Consider the following variable:
type Small is range -128 .. 127;
SR : Small := 48;
Trying to get its value as an integer within Python code yields:
(gdb) python sr = gdb.parse_and_eval('sr')
(gdb) python print int(sr)
Traceback (most recent call last):
File "<string>", line 1, in <module>
gdb.error: Cannot convert value to int.
Error while executing Python code.
This is happening because our variable is a range type, and
py-value's is_intlike does not handle TYPE_CODE_RANGE. This
patch fixes this.
gdb/ChangeLog:
* python/py-value.c (is_intlike): Add TYPE_CODE_RANGE handling.
gdb/testsuite/ChangeLog:
* gdb.ada/py_range: New testcase.

Fix GDB crash with upstream GCC due to memcpy(NULL, ...)

Start inferior before running test listing Ada exceptions.
This patch fixes some spurious failures when the inferior is linked
against the shared version of libgnat by default, as appears to be
the case on many GNU/Linux distributions. When that happens, we have
to start the program in order to ensure that the GNAT runtime is

fix PR c++/16117
This patch fixes PR c++/16117.
gdb has an extension so that users can use expressions like FILE::NAME
to choose a variable of the given name from the given file. The bug
is that this extension takes precedence over ordinary C++ expressions
of the same form. You might think this is merely hypothetical, but
now that C++ headers commonly do not use an extension, it is more
common.
This patch fixes the bug by making two related changes. First, it
changes gdb to prefer the ordinary C++ meaning of a symbol over the
extended meaning. Second, it arranges for single-quoting of the
symbol to indicate a preference for the extension.
Built and regtested on x86-64 Fedora 18.

Fix DW_OP_GNU_regval_type with FP registers
Consider the following code, compiled at -O2 on ppc-linux:
procedure Increment (Val : in out Float; Msg : String);
The implementation does not really matter in this case). In our example,
this function is being called from a function with Param_1 set to 99.0.
Trying to break inside that function, and running until reaching that
breakpoint yields:
(gdb) b increment
Breakpoint 1 at 0x100014b4: file callee.adb, line 6.
(gdb) run
Starting program: /[...]/foo
Breakpoint 1, callee.increment (val=99.0, val@entry=0.0, msg=...)
at callee.adb:6
6 if Val > 200.0 then
The @entry value for parameter "val" is incorrect, it should be 99.0.
The associated call-site parameter DIE looks like this:
.uleb128 0xc # (DIE (0x115) DW_TAG_GNU_call_site_parameter)
.byte 0x2 # DW_AT_location
.byte 0x90 # DW_OP_regx
.uleb128 0x21
.byte 0x3 # DW_AT_GNU_call_site_value
.byte 0xf5 # DW_OP_GNU_regval_type
.uleb128 0x3f
.uleb128 0x25
The DW_AT_GNU_call_site_value uses a DW_OP_GNU_regval_type
operation, referencing register 0x3f=63, which is $f31,
an 8-byte floating register. In that register, the value is
stored using the usual 8-byte float format:
(gdb) info float
f31 99.0 (raw 0x4058c00000000000)
The current code evaluating DW_OP_GNU_regval_type operations
currently is (dwarf2expr.c:execute_stack_op):
result = (ctx->funcs->read_reg) (ctx->baton, reg);
result_val = value_from_ulongest (address_type, result);
result_val = value_from_contents (type,
value_contents_all (result_val));
What the ctx->funcs->read_reg function does is read the contents
of the register as if it contained an address. The rest of the code
continues that assumption, thinking it's OK to then use that to
create an address/ulongest struct value, which we then re-type
to the type specified by DW_OP_GNU_regval_type.
We're getting 0.0 above because the read_reg implementations
end up treating the contents of the FP register as an integral,
reading only 4 out of the 8 bytes. Being a big-endian target,
we read the high-order ones, which gives us zero.
This patch fixes the problem by introducing a new callback to
read the contents of a register as a given type, and then adjust
the handling of DW_OP_GNU_regval_type to use that new callback.

random_signal = (sval == BPSTAT_SIGNAL_NO);
if (sval == BPSTAT_SIGNAL_HIDE)

We can observe:
- the stepping checks bit:
...
|| ecs->event_thread->control.trap_expected
|| (ecs->event_thread->control.step_range_end
&& (ecs->event_thread->control.step_resume_breakpoint
== NULL)));
...
is just like currently_stepping:
static int
currently_stepping (struct thread_info *tp)
{
return ((tp->control.step_range_end
&& tp->control.step_resume_breakpoint == NULL)
|| tp->control.trap_expected
|| bpstat_should_step ());
}
except it misses the bpstat_should_step check (***).
It's not really necessary to check bpstat_should_step in the
random signal tests, because software watchpoints always end up in
the bpstat list anyway, which means bpstat_explains_signal with
GDB_SIGNAL_TRAP always returns at least BPSSTAT_SIGNAL_HIDE, but I
think the code is clearer if we reuse currently_stepping.
*** - bpstat_should_step checks to see if there's any software
watchpoint in the breakpoint list, because we need to force the
target to single-step all the way, to evaluate the watchpoint's
value at each step.
- we never hide GDB_SIGNAL_TRAP, even if the bpstat returns
BPSTAT_SIGNAL_HIDE, which is actually the default for all
breakpoints. If we make the default be BPSTAT_SIGNAL_PASS, then

testsuite/gdb.dwarf2: dw2-case-insensitive.exp: p fuNC_lang fails on arm
dw2-case-insensitive.exp: p fuNC_lang fails on arm. The problem occurs
when thumb mode code is generated. On ARM last bit of function pointer
value indicates whether the target function is an ARM (if 0) or Thumb
(if 1) routine. The PC address should refer to actual address in
either case. This patch adds new compile unit and function labels to
code which act as address ranges of compile unit and functions in
debug information. Therefore address ranges will have correct
addresses and not the ones with an incremented least significant bit.

GDB/MI: Add new "--language LANG" command option.
Frontend sometimes need to evaluate expressions that are
language-specific. For instance, Eclipse uses the following
expression to determine the size of an address on the target:
-data-evaluate-expression "sizeof (void*)"
Unfortunately, if the main of the program being debugged is not C,
this may not work. For instance, if the main is in Ada, you get...
-data-evaluate-expression "sizeof (void*)"
^error,msg="No definition of \"sizeof\" in current context."
... and apparently decides to stop the debugging session as a result.
The recommendation sent was to specifically set the language to C
before trying to evaluate the expression. Something such as:
1. save current language
2. set language c
3. -data-evaluate-expression "sizeof (void*)"
4. Restore language
This has the same disadvantages as the ones outlined in the "Context
Management" section of the GDB/MI documentation regarding setting
the current thread or the current frame, thus recommending the use of
general command-line switches such as --frame, or --thread instead.
This patch follows the same steps for the language, adding a similar
new command option: --language LANG. Example of use:
-data-evaluate-expression --language c "sizeof (void*)"
^done,value="4"

crash while re-reading symbols from objfile on ppc-aix.
This patch aims at fixing the following problem, where the user:
. debugs its program
. makes a modification and rebuilds it *without exiting the debugger*
. returns to its debugging session and restarts the inferior
In that situation, the debugger notices that the underlying executable
has changed and that re-reading its symbols is needed. Shortly after
displaying a message informing the user of the situation, GDB crashes:
(gdb) run
[...]
`/[...]/dest' has changed; re-reading symbols.
zsh:
13434922 segmentation fault (core dumped)
The crash occurs while trying to allocate some memory on the bfd_bfd
obstack. But, at some point in time, the whole obstack data gets
corrupted, nullified. So the memory allocation fails trying to call
a function at a NULL address. (side note: when debugging GDB in GDB,
top-gdb reports a SIGILL, while the shell makes it look like it was
a SIGSEGV - the discrepancy is not critical to the investigation
and therefore was not explored)
The corruption occurred because the region where the per_bfd data
got free'ed nearly after it got allocated! This is what happens,
in chronological order (see reread_symbols):
1. GDB notices that the executable has changed, decides to
re-read its symbols.
2. Opens a new bfd, unrefs the old one
3. Calls set_objfile_per_bfd (objfile);
4. Re-initializes the objfile's obstack:
obstack_init (&objfile->objfile_obstack);
I think that the normal behavior for set_objfile_per_bfd would
be to search for already-allocated shared per_bfd data, and
allocate new one if not found. The critical difference between
a platform such as x86_64-linuxe where it works, and ppc-aix,
where it doesn't lies in the fact that bfd-data sharing is not
activated on ppc-aix, and as a result, the per-bfd data gets
allocated on the objfile's obstack instead of in the bfd objalloc:
/* If the object requires gdb to do relocations, we simply fall
back to not sharing data across users. These cases are rare
enough that this seems reasonable. */
if (abfd != NULL && !gdb_bfd_requires_relocations (abfd))
{
storage = bfd_zalloc (abfd, sizeof (struct objfile_per_bfd_storage));
set_bfd_data (abfd, objfiles_bfd_data, storage);
}
else
storage = OBSTACK_ZALLOC (&objfile->objfile_obstack,
struct objfile_per_bfd_storage);
Allocating that per_bfd storage is of course nearly useless since
we end up free-ing right after in step (4) above. Eventually,
the memory region ends up being re-used, hence the corruption
leading to the crash.
This fix was simply to move the call to set_objfile_per_bfd after
the objfile's obstack re-initialization.

* symfile.c (reread_symbols): Move call to set_objfile_per_bfd

Add command to list Ada exceptions
This patch adds a new command "info exceptions" whose purpose is to
provide the list of exceptions currently defined in the inferior.
The usage is:

Without argument, the command lists all exceptions. Otherwise,
only those whose name match REGEXP are listed.
For instance:
(gdb) info exceptions
All defined Ada exceptions:
constraint_error: 0x613dc0

I inherited long ago. It's output being parsed by frontends such as
GPS, I cannot easily change it. Same for the command name.
The implementation is mostly self-contained, and is written in a way
that should make it easy to implement the GDB/MI equivalent. The
careful reviewer will notice that the code added in ada-lang.h could
normally be made private inside ada-lang.c. But these will be used
