(longjmp_breakpoint_ops): New variable. (update_breakpoints_after_exec, breakpoint_init_inferior): Delete also bp_longjmp_call_dummy. (bpstat_what, bptype_string, print_one_breakpoint_location) (init_bp_location): Support bp_longjmp_call_dummy. (set_longjmp_breakpoint): Use longjmp_breakpoint_ops. Comment why. (set_longjmp_breakpoint_for_call_dummy) (check_longjmp_breakpoint_for_call_dummy, longjmp_bkpt_dtor): New functions. (initialize_breakpoint_ops): Initialize longjmp_breakpoint_ops. * breakpoint.h (enum bptype): New item bp_longjmp_call_dummy. Delete FIXME comment and extend the other comment for bp_call_dummy. (set_longjmp_breakpoint_for_call_dummy) (check_longjmp_breakpoint_for_call_dummy): New declarations. * dummy-frame.c: Include gdbthread.h. (pop_dummy_frame_bpt): New function. (pop_dummy_frame): Call pop_dummy_frame_bpt. (dummy_frame_discard): New function. (cleanup_dummy_frames): Update the comment about longjmps. * dummy-frame.h (dummy_frame_discard): New declaration. * gdbthread.h (struct thread_info): Extend initiating_frame comment. * infcall.c (call_function_by_hand): New variable longjmp_b. Call set_longjmp_breakpoint_for_call_dummy. Chain its breakpoints with BPT. * infrun.c (handle_inferior_event) : Add case 4 comment. Call check_longjmp_breakpoint_for_call_dummy and keep_going if IS_LONGJMP and there is no other reason to stop. gdb/testsuite/ Remove stale dummy frames. * gdb.base/call-signal-resume.exp (maintenance print dummy-frames) (maintenance info breakpoints): New tests. * gdb.base/stale-infcall.c: New file. * gdb.base/stale-infcall.exp: New file. --- gdb/gdbthread.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'gdb/gdbthread.h') diff --git a/gdb/gdbthread.h b/gdb/gdbthread.h index 2512357..7cd66b6 100644 --- a/gdb/gdbthread.h +++ b/gdb/gdbthread.h @@ -216,7 +216,9 @@ struct thread_info int stop_requested; /* The initiating frame of a nexting operation, used for deciding - which exceptions to intercept. */ + which exceptions to intercept.
