* dummy-frame.c (dummy_frame): Replace regcache member with
caller_state.
(dummy_frame_push): Replace caller_regcache arg with caller_state.
All callers updated.
(remove_dummy_frame,pop_dummy_frame,lookup_dummy_frame): New fns.
(dummy_frame_pop): Rewrite. Verify requested frame is in the
dummy frame stack. Restore program state.
(cleanup_dummy_frames): Rewrite.
(dummy_frame_sniffer): Update. Make static.
* dummy-frame.h (regcache,frame_info): Delete forward decls.
(inferior_thread_state): New forward decl.
(dummy_frame_push): Update prototype.
* frame.c (frame_pop): dummy_frame_pop now does all the work for
DUMMY_FRAMEs.
* infcall.c (breakpoint_auto_delete_contents): Delete.
(get_function_name,run_inferior_call): New fns.
(call_function_by_hand): Simplify by moving some code to
get_function_name, run_inferior_call. Inferior function call wrapped
in TRY_CATCH so there's less need for cleanups and all exits from
proceed are handled similarily. Detect program exit.
Detect program stopping in a different thread.
Make error messages more consistent.
* inferior.h (inferior_thread_state): Declare (opaque type).
(save_inferior_thread_state,restore_inferior_thread_state,
make_cleanup_restore_inferior_thread_state,
discard_inferior_thread_state, get_inferior_thread_state_regcache):
Declare.
(save_inferior_status): Update prototype.
* infrun.c: (normal_stop): When stopped for the completion of an
inferior function call, verify the expected stack frame kind.
(inferior_thread_state): New struct.
(save_inferior_thread_state,restore_inferior_thread_state,
do_restore_inferior_thread_state_cleanup,
make_cleanup_restore_inferior_thread_state,
discard_inferior_thread_state,
get_inferior_thread_state_regcache): New functions.
(inferior_status): Move stop_signal, stop_pc, registers to
inferior_thread_state. Remove restore_stack_info.
(save_inferior_status): Remove arg restore_stack_info.
All callers updated. Remove saving of state now saved by
save_inferior_thread_state.
(restore_inferior_status): Remove restoration of state now done by
restore_inferior_thread_state.
(discard_inferior_status): Remove freeing of registers, now done by
discard_inferior_thread_state.
* gdb.base/break.exp: Update expected gdb output.
* gdb.base/sepdebug.exp: Ditto.
* gdb.mi/mi-syn-frame.exp: Ditto.
* gdb.mi/mi2-syn-frame.exp: Ditto.
* gdb.base/call-signal-resume.exp: New file.
* gdb.base/call-signals.c: New file.
* gdb.base/unwindonsignal.exp: New file.
* gdb.base/unwindonsignal.c: New file.
* gdb.threads/interrupted-hand-call.exp: New file.
* gdb.threads/interrupted-hand-call.c: New file.
* gdb.threads/thread-unwindonsignal.exp: New file.
