* breakpoint.h (enum bpdisp): Add del_at_next_stop.
* breakpoint.c (insert_breakpoints, watchpoint_check,
bpstat_stop_status): Avoid bad references to memory freed via
delete_breakpoint on watchpoints going out of scope.
Do not delete these watchpoints, disable them and change their
disposition to del_at_next_stop instead.
(breakpoint_auto_delete): Delete all breakpoints whose disposition
is del_at_next_stop.
(breakpoint_init_inferior): Use switch to avoid reference to
already deleted breakpoint.
Fixes dangling pointer problems with watchpoints.
(bpstat_what_main_action): New code BPSTAT_WHAT_THROUGH_SIGTRAMP.
* breakpoint.c (bpstat_what): Return BPSTAT_WHAT_THROUGH_SIGTRAMP
if we hit a bp_through_sigtramp breakpoint. Remove kludge which
ignored bs->stop for a bp_step_resume breakpoint.
* infrun.c (wait_for_inferior): Make a through_sigtramp_breakpoint
which performs one (the check_sigtramp2 one) of the functions
which had been handled by the step_resume_breakpoint. For each
use of the step_resume_breakpoint, make it still use the
step_resume_breakpoint, use the through_sigtramp_breakpoint, or
operate on both.
Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
When setting the frame address of the step resume breakpoint, set
it to the address for frame *before* the call instruction is
executed, not after.
that clears the `inserted' flag for all breakpoints and deletes
any breakpoints which should go away between runs of programs.
* inflow.c (generic_mourn_inferior), infrun.c (init_wait_for_inferior),
remote-es.c (es1800_load), comments in exec.c and corelow.c:
Use it instead of mark_breakpoints_out.
* breakpoint.c (mark_breakpoints_out): Update comment, tm-rs6000.h
uses it in a completely different context.
* breakpoint.c (breakpoint_re_set_one): Add bp_call_dummy case.
Some of the following is in #ifdef CALL_DUMMY_BREAKPOINT_OFFSET.
* breakpoint.h (enum bptype): Add bp_call_dummy.
(struct bpstat_what): Add call_dummy field.
* infrun.c (wait_for_inferior): Deal with it.
* breakpoint.c (bpstat_what): Deal with call dummy breakpoint.
* infcmd.c (run_stack_dummy): Set the call dummy breakpoint.
* config/sparc/tm-sparc.h: Define CALL_DUMMY_BREAKPOINT_OFFSET.
Remove bpstat_momentary_breakpoint. This was always kludgy
and is no longer used.
* breakpoint.h: Add enum bpstat_what.
breakpoint.h (struct bpstat), breakpoint.c (bpstat_stop_status):
stop and print fields of bpstat now per-breakpoint, not just
one for the whole chain.
breakpoint.{c,h} (bpstat_what): New function.
breakpoint.h: Remove bpstat_stop and bpstat_should_print.
infrun.c: Replace switch (stop_bpstat->breakpoint_at->type)
with call to bpstat_what.
README: Remove watchpoint/breakpoint bug from known bugs.
* breakpoint.h: Prototype bpstat_find_breakpoint.
breakpoint.h, tm-sun4os4.h, tm-sparc.h, sparc-tdep.c, tm-mips.h,
mips-tdep.h, tm-sun3.h, tm-68k.h, m68k-tdep.h: Add support for
stepping (and nexting) through longjmp(). Also, cleanup
breakpoint handling quite a bit by creating explicit breakpoint
types instead of using magic breakpoint numbers.
