Report overflow on PowerPC64 @h and @ha relocations.

This changes the behaviour of @h and @ha on PowerPC64 to report errors
on 32-bit overflow.  The motivation for this change is that on
PowerPC64, most uses of @h and @ha modifiers and their corresponding
relocations are to build up 32-bit offsets.  We'd like to know when
such offsets overflow.  Only rarely do people use @h or @ha with the
high 32-bit modifiers to build a 64-bit constant.  Those uses will now
need to use two new modifiers, @high and @higha, if the constant isn't
known at assembly time.  For now, we won't report overflow at assembly
time..

relocations.

With:

 struct static_struct { static int aaa; };
 struct static_struct sss;
 int main () { return 0; }

We get:

 (gdb) p sss

 (gdb) p sss.aaa
 field aaa is nonexistent or has been optimized out

Note that the "field aaa ..." message is an error being thrown.

GDB is graceful everywhere else when printing optimized out values.
IOW it usually prints an <optimized out> value and puts that in the
value history.  I see no reason for here to be different, more so that
when the print the whole "containing" object (well, it's a static
field, so it's not really a container), we already print <optimized

After the patch:

 (gdb) p sss
 $1 = {static aaa = <optimized out>}

The value_entirely_optimized_out checks are there to preserve
behavior.  Without those, if the static field is a struct/union, GDB
would go and print its fields one by one (and print <optimized out>

11 years agoinfrun debug output: print enum gdb_signal symbol names instead of POSIX signal names.
Pedro Alves [Wed, 23 Oct 2013 15:14:53 +0000 (16:14 +0100)]
infrun debug output: print enum gdb_signal symbol names instead of POSIX signal names.

The other day while debugging something related to random signals, I
got confused with "set debug infrun 1" output, for it said:

 infrun: TARGET_WAITKIND_STOPPED
 infrun: stop_pc = 0x323d4e8b94
 infrun: random signal 20

On GNU/Linux, 20 is SIGTSTP.  For some reason, it took me a few
minutes to realize that 20 is actually a GDB signal number, not a
target signal number (duh!).  In any case, I propose making GDB's
output clearer here:

One way would be to use gdb_signal_to_name, like already used
elsewhere:

 infrun: TARGET_WAITKIND_STOPPED
 infrun: stop_pc = 0x323d4e8b94
 infrun: random signal SIGCHLD (20)

but I think that might confuse someone too ("20? Why does GDB believe
SIGCHLD is 20?").  So I thought of printing the enum string instead:

 infrun: TARGET_WAITKIND_STOPPED
 infrun: stop_pc = 0x323d4e8b94
 infrun: random signal GDB_SIGNAL_CHLD (20)

Looking at a more complete infrun debug log, we had actually printed
the (POSIX) signal name name a bit before:

 infrun: target_wait (-1, status) =
 infrun:   9300 [Thread 0x7ffff7fcb740 (LWP 9300)],
 infrun:   status->kind = stopped, signal = SIGCHLD
 ...
 infrun: TARGET_WAITKIND_STOPPED
 infrun: stop_pc = 0x323d4e8b94
 infrun: random signal 20

So I'm now thinking that it'd be even better to make infrun output
consistently use the enum symbol string, like so:

 infrun: clear_proceed_status_thread (Thread 0x7ffff7fca700 (LWP 25663))

GDB's signal numbers are public and hardcoded (see
include/gdb/signals.h), so there's really no need to clutter the
output with numeric values in some places while others not.  Replacing
the magic "144" with GDB_SIGNAL_DEFAULT in "proceed"'s debug output
(see above) I think is quite nice.

I posit that all this makes it clearer to newcomers that GDB has its
own signal numbering (and that there must be some mapping going on).

Tested on x86_64 Fedora 17.

Fix off-by-one errors in *scanf format strings.

In the first hunk, the format string was off-by-one for cmd, and cmd
itself was larger than the maximum size required.  cmd was reduced in
size and the format string adjusted.

In the second hunk, the format string was off-by-one for local_address,
remote_address and extra, although the buffers for the two addresses
were large enough for this not to matter.  The specifiers for the two
addresses was corrected, and a number of unused variables including
extra were suppressed from parsing.

In the third hunk, the format string was off-by-one for name,
dependencies and status.  This code was rewritten using strtok since
dependencies can be arbitrarily long.

Remove dead sets/clears of ecs->random signal.

'*ecs' is always memset by handle_inferior_event's callers, so all
these clears are unnecessary.  There's one place that sets the flag to
true, but, afterwards, before ecs->random_signal is ever read, we
reach the part of handle_inferior_even that clears ecs->random_signal,
among other things:

  clear_stop_func (ecs);
  ecs->event_thread->stepping_over_breakpoint = 0;
  bpstat_clear (&ecs->event_thread->control.stop_bpstat);
  ecs->event_thread->control.stop_step = 0;
  stop_print_frame = 1;
  ecs->random_signal = 0;

 infrun: random signal 20
 infrun: stepi/nexti
 infrun: stop_stepping

So the inferior got a SIGCHLD (because the fork child exited while
we're doing 'si'), and since that signal is set to "nostop noprint
pass" (by default), it's considered a random signal, so it should not
cause a stop.  But, it resulted in an immediate a stop_stepping call
anyway.  So the single-step never really finished.

This is a regression caused by:

part.  However, if we don't have a stepped thread to get back to,
we'll now also fall through to all the "stepping" tests.  For line
stepping, that'll turn out okay, as we'll just end up realizing the
thread is still in the stepping range, and needs to be re-stepped.
However, for stepi/nexti, we'll reach:

      stop_stepping (ecs);
      return;
    }

and stop, even though the thread actually made no progress.  The fix
is to restore the keep_going call, but put it after the "switch back
to the stepped thread" code, and before the stepping tests.

fix for PR gdb/15995

This patch fixes PR gdb/15995.

The bug here is that gdb's printf command does not flush the output
stream.  This makes a printf that is not newline-terminated interleave
incorrectly with other forms of output, such as that generated via a
call to an external program using "shell".

I note that the "output" command already does this flushing.

The fix is to call gdb_flush in printf_command.
