From ce4c476a0f4f38e08bce87f4144aaa7550e9a79d Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 23 May 2013 17:12:51 +0000 Subject: [PATCH] Factor out in-stepping-range checks. This adds a function for doing within-thread's-stepping-range checks, and converts a couple spots to use it. Following patches will add more uses. gdb/ 2013-05-23 Yao Qi Pedro Alves * gdbthread.h (pc_in_thread_step_range): New declaration. * thread.c (pc_in_thread_step_range): New function. * infrun.c (handle_inferior_event): Use it. --- gdb/ChangeLog | 7 +++++++ gdb/gdbthread.h | 4 ++++ gdb/infrun.c | 6 ++---- gdb/thread.c | 7 +++++++ 4 files changed, 20 insertions(+), 4 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 1c21cd4668..3389c9fc64 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,10 @@ +2013-05-23 Yao Qi + Pedro Alves + + * gdbthread.h (pc_in_thread_step_range): New declaration. + * thread.c (pc_in_thread_step_range): New function. + * infrun.c (handle_inferior_event): Use it. + 2013-05-23 Joel Brobecker * mi/mi-cmd-break.c (mi_argv_to_format): Use xsnprintf instead diff --git a/gdb/gdbthread.h b/gdb/gdbthread.h index 0846322725..a9f8a941df 100644 --- a/gdb/gdbthread.h +++ b/gdb/gdbthread.h @@ -399,6 +399,10 @@ extern struct thread_info* inferior_thread (void); extern void update_thread_list (void); +/* Return true if PC is in the stepping range of THREAD. */ + +int pc_in_thread_step_range (CORE_ADDR pc, struct thread_info *thread); + extern struct thread_info *thread_list; #endif /* GDBTHREAD_H */ diff --git a/gdb/infrun.c b/gdb/infrun.c index 54e92f2318..57c427da6d 100644 --- a/gdb/infrun.c +++ b/gdb/infrun.c @@ -4337,8 +4337,7 @@ process_event_stop_test: if (ecs->event_thread->control.step_range_end != 0 && ecs->event_thread->suspend.stop_signal != GDB_SIGNAL_0 - && (ecs->event_thread->control.step_range_start <= stop_pc - && stop_pc < ecs->event_thread->control.step_range_end) + && pc_in_thread_step_range (stop_pc, ecs->event_thread) && frame_id_eq (get_stack_frame_id (frame), ecs->event_thread->control.step_stack_frame_id) && ecs->event_thread->control.step_resume_breakpoint == NULL) @@ -4707,8 +4706,7 @@ process_event_stop_test: through a function epilogue and therefore must detect when the current-frame changes in the middle of a line. */ - if (stop_pc >= ecs->event_thread->control.step_range_start - && stop_pc < ecs->event_thread->control.step_range_end + if (pc_in_thread_step_range (stop_pc, ecs->event_thread) && (execution_direction != EXEC_REVERSE || frame_id_eq (get_frame_id (frame), ecs->event_thread->control.step_frame_id))) diff --git a/gdb/thread.c b/gdb/thread.c index 2a1d7239b3..2eb506bb7c 100644 --- a/gdb/thread.c +++ b/gdb/thread.c @@ -750,6 +750,13 @@ finish_thread_state_cleanup (void *arg) finish_thread_state (*ptid_p); } +int +pc_in_thread_step_range (CORE_ADDR pc, struct thread_info *thread) +{ + return (pc >= thread->control.step_range_start + && pc < thread->control.step_range_end); +} + /* Prints the list of threads and their details on UIOUT.
