Pedro Alves 31e77af205 PR breakpoints/7143 - Watchpoint does not trigger when first set
Say the program is stopped at a breakpoint, and the user sets a
watchpoint.  When the program is next resumed, GDB will first step
over the breakpoint, as explained in the manual:

  @value {GDBN} normally ignores breakpoints when it resumes
  execution, until at least one instruction has been executed.  If it
  it did not do this, you would be unable to proceed past a breakpoint
  without first disabling the breakpoint.  This rule applies whether
  or not the breakpoint already existed when your program stopped.

However, GDB currently also removes watchpoints, catchpoints, etc.,
and that means that the first instruction off the breakpoint does not
trigger the watchpoint, catchpoint, etc.

testsuite/gdb.base/watchpoint.exp has a kfail for this.

The PR proposes installing watchpoints only when stepping over a
breakpoint, but that misses catchpoints, etc.

A better fix would instead work from the opposite direction -- remove
only real breakpoints, leaving all other kinds of breakpoints
inserted.

But, going further, it's really a waste to constantly remove/insert
all breakpoints when stepping over a single breakpoint (generating a
pair of RSP z/Z packets for each breakpoint), so the fix goes a step
further and makes GDB remove _only_ the breakpoint being stepped over,
leaving all others installed.  This then has the added benefit of
reducing breakpoint-related RSP traffic substancialy when there are
many breakpoints set.

For now, let's focus only on the *stopped event.  We see that the
async output is missing frame info.  And this causes a test failure in
async mode, as "mi_expect_stop solib-event" wants to see the frame
info.

However, if we compare the event output when a real MI execution
command is used, compared to a CLI command (e.g., run vs -exec-run,
next vs -exec-next, etc.), we see:

As seen above, with MI commands, the *stopped event _doesn't_ have
frame info.  This is because normal_stop, as commanded by the result
of bpstat_print, skips printing frame info in this case (it's an
"event", not a "breakpoint"), and when the interpreter is MI,
mi_on_normal_stop skips calling print_stack_frame, as the normal_stop
call was already done with the MI uiout.  This explains why the async
output is different even with a CLI command.  Its because in async
mode, the mi_on_normal_stop path is always taken; it is always reached
with the MI uiout, because the stop is handled from the event loop,
instead of from within `proceed -> wait_for_inferior -> normal_stop'
with the interpreter overridden, as in sync mode.

This patch fixes the issue by making all cases output the same
*stopped event, by factoring out the print code from normal_stop, and
using it from mi_on_normal_stop as well.  I chose the *stopped output
without a frame, mainly because that is what you already get if you
use MI execution commands, the commands frontends are supposed to use
(except when implementing a console).  This patch makes it simpler to
tweak the MI output differently if desired, as we only have to change
the centralized print_stop_event (taking into account whether the
uiout is MI-like), and all different modes will change accordingly.

Tested on x86_64 Fedora 17, no regressions.  The mi-solib.exp test no
longer fails in async mode with this patch, so the patch removes the
kfail.

Pedro Alves d6b6434614 Rename native-only terminal related functions.
Looking at target_terminal_inferior etc. in async mode, I realized
that the naming of the terminal_inferior, terminal_ours,
etc. functions doesn't really give a clue that they're meant for the
native target only.  This patch renames them.  There's already
child_terminal_info using the child_ prefix, and, they're most
prominently installed by inf-child.c, so I went with the child_
prefix.  I dropped "inferior" from a couple to make the name match the
corresponding target method.

Tested on x86_64 Fedora 17, and cross built for mingw.  I didn't test
gnu-nat.c, but I think the change is as obvious as it gets.  I grepped
the tree looking for other potential spots that would need adjustment
but this is all I found.  If something breaks, it should be trivial to
fix.

Pedro Alves 98882a2651 Make STARTUP_WITH_SHELL a runtime toggle -- add new "set/show startup-with-shell" option.
Occasionaly we hear about people having problems with GDB not being
able to start programs (with "run"/"start").  GDB spawns a shell to
start the program, and most often, it'll be the case that the problem
is actually with the user's shell setup.

GDB has code to disable the use of the shell to start programs.
That's the STARTUP_WITH_SHELL macro that native targets could set to 0
in their nm.h file (though no target actually uses it nowadays).

This patch makes that setting a run-time knob instead.  This will be
useful to quickly diagnose such shell issues, and might also come in
handy at other times (such as when debugging the shell itself, if you
don't have a different shell handy).

Sergio Durigan Junior 0c5571793a This patch adds a new convenience variable called "$_exitsignal", which
will hold the signal number when the inferior terminates due to the
uncaught signal.

I've made modifications on infrun.c:handle_inferior_event such that
$_exitcode gets cleared when the inferior signalled, and vice-versa.
This assumption was made because the variables are mutually
exclusive, i.e., when the inferior terminates because of an uncaught
signal it is not possible for it to return.  I have also made modifications
such that when a corefile is loaded, $_exitsignal gets set to the uncaught
signal that "killed" the inferior, and $_exitcode is cleared.

The patch also adds a NEWS entry, documentation bits, and a testcase.  The
documentation entry explains how to use $_exitsignal and $_exitcode in a
GDB script, by making use of the new $_isvoid convenience function.
