In the case where the GNAT runtime was built with full debugging info,
several of the exceptions defined there might have a name contain
the word "global". To make this less likely, this patch renames
the exception name, replacing "Global" by "Global_GDB". It still
keeps the exeption name relatively short, while it is unlikely that
the GNAT runtime has an exception whose name explicitly mentions GDB,
and even less likely that it contains "Global_GDB".

Similar to qsort(), the glibc version of memcpy() also declares its
arguments with __attribute__(__nonnull__(...)). If NULL is passed
anyway, upstream GCC's new pass '-fisolate-erroneous-paths' typically

chain_candidate() when trying to execute the break.exp test case.

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
mapped to memory, in order for us to find the standard exceptions
(defined within the runtime). Otherwise, they will not be shown,
as expected, by the debugger.

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.

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.

ELFv2 needs different plt call stubs to ELFv1, register usage differs

Before all this stop_soon handling, we have code that can end in
keep_going. Particularly, the thread_hop_needed code looked
suspicious considering breakpoint always-inserted mode, though on
closer inspection, it'd take connecting to multiple remote targets
that shared the same address space to trigger that.
Still, I think it's clearer if all this remote connection setup /
attach code is placed early, before any keep_going path could be
reached.

* infrun.c (handle_signal_stop): Move STOP_QUIETLY,

After the previous patches, we only ever reach the code after the
initial 'switch (ecs->ws.kind)' switch for TARGET_WAITKIND_STOPPED.
We can now factor out all that to its own function.
Unfortunately, stepped_after_stopped_by_watchpoint needed to move to
the ecs. I think that indicates a state machine bug -- no event other
than TARGET_WAITKIND_STOPPED indicates a single-step actually
finished. TARGET_WAITKIND_SYSCALL_XXX, TARGET_WAITKIND_FORK, etc. are
all events that are triggered from the kernel, _within_ a syscall,
IOW, from userspace's perspective, halfway through an instruction
being executed. This might actually matter for the syscall events, as
syscalls can change memory (and thus trigger watchpoints).

After the previous patch, there's actually no breakpoint type that

bpstat_explains_signal return a boolean. The signal hiding actually
disappears.

bpstat_explains_signal now returns a boolean - adjust. No longer
consider hiding signals.
Looking at the current random signal checks:
if (ecs->event_thread->suspend.stop_signal == GDB_SIGNAL_TRAP)
random_signal
= !((bpstat_explains_signal (ecs->event_thread->control.stop_bpstat,
GDB_SIGNAL_TRAP)
!= BPSTAT_SIGNAL_NO)
|| stopped_by_watchpoint
|| ecs->event_thread->control.trap_expected
|| (ecs->event_thread->control.step_range_end
&& (ecs->event_thread->control.step_resume_breakpoint
== NULL)));
else
{
enum bpstat_signal_value sval;
sval = bpstat_explains_signal (ecs->event_thread->control.stop_bpstat,
ecs->event_thread->suspend.stop_signal);
random_signal = (sval == BPSTAT_SIGNAL_NO);
if (sval == BPSTAT_SIGNAL_HIDE)
ecs->event_thread->suspend.stop_signal = GDB_SIGNAL_0;
}
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
we can merge the two bpstat_explains_signal paths.

This goes a step forward in making only TARGET_WAITKIND_STOPPED talk
about signals.
There's no reason for the "catchpoint" TARGET_WAITKIND_XXXs to consult
bpstat about signals -- unlike breakpoints, all these events are
continuable, so we don't need to do a remove-break/step/reinsert-break
-like dance. That means we don't actually need to run them through
process_event_stop_test (for the bpstat_what checks), and can just use
bpstat_causes_stop instead. Note we were already using it in the
TARGET_WAITKIND_(V)FORKED cases.
Then, these "catchpoint" waitkinds don't need to set
ecs->random_signal for anything, because they check it immediately
afterwards (and the value they set is never used again).

Of all the TARGET_WAITKIND_XXXs event kinds other than
TARGET_WAITKIND_STOPPED, TARGET_WAITKIND_LOADED is the only kind that
doesn't end in a return, instead falling through to all the
signal/breakpoint/stepping handling code. But it only falls through
in the STOP_QUIETLY_NO_SIGSTOP and STOP_QUIETLY_REMOTE cases, which
means the
/* This is originated from start_remote(), start_inferior() and
shared libraries hook functions. */
if (stop_soon == STOP_QUIETLY || stop_soon == STOP_QUIETLY_REMOTE)
{
if (debug_infrun)
fprintf_unfiltered (gdb_stdlog, "infrun: quietly stopped\n");
stop_stepping (ecs);
return;
}
bit is eventually reached. All tests before that is reached will
always fail. It's simpler to inline the stop_soon checks close to the
TARGET_WAITKIND_LOADED code, which allows removing the fall through.
Tested on x86_64 Fedora 17, but that doesn't exercise this
TARGET_WAITKIND_LOADED.
Also ran gdb.base/solib-disc.exp on Cygwin/gdbserver, which exercises
reconnection while the inferior is stopped at an solib event, but then
again, gdbserver always replies a regular trap on initial connection,
instead of the last event the program had seen:
Sending packet: $?#3f...Packet received: T0505:4ca72800;04:f8a62800;08:62fcc877;thread:d28;
Sending packet: $Hc-1#09...Packet received: E01
Sending packet: $qAttached#8f...Packet received: 0
Packet qAttached (query-attached) is supported
infrun: clear_proceed_status_thread (Thread 3368)
Sending packet: $qOffsets#4b...Packet received:
infrun: wait_for_inferior ()
infrun: target_wait (-1, status) =

infrun: infwait_normal_state
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x77c8fc62

So the only way to exercise this would be to hack gdbserver. I didn't
go that far though. I'm reasonably confident this is correct.

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.

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*)"

* ld-arm/script-type.sym: Remove redundant STT_FILE symbol.
I noticed today that multi-arch-exec.exp was failing in parallel mode.
The bug is that multi-arch-exec.c assumes the non-parallel directory
layout.
This patch fixes the problem using the same "BASEDIR" approach used in
other tests.
Tested both ways on x86-64 Fedora 18.
I'm checking this in.

* gdb.multi/multi-arch-exec.exp: Define BASEDIR when compiling.
* gdb.multi/multi-arch-exec.c (main): Use BASEDIR.
