From: Pedro Alves Date: Thu, 27 Mar 2014 18:43:59 +0000 (+0000) Subject: infrun.c: simplify "end stepping range" code a bit. X-Git-Tag: gdb-7.8-release~217 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bdc36728eee582853ca53bb8b6012e8cc3b90eb7;p=platform%2Fupstream%2Fbinutils.git infrun.c: simplify "end stepping range" code a bit. - all end_stepping_range callers also set stop_step. - all places that set stop_step call end_stepping_range and stop_waiting too. IOW, all places where we handle "end stepping range" do: ecs->event_thread->control.stop_step = 1; end_stepping_range (); stop_waiting (ecs); Factor that out into end_stepping_range itself. Tested on x86_64 Fedora 20. gdb/ 2014-05-29 Pedro Alves * infrun.c (process_event_stop_test, handle_step_into_function) (handle_step_into_function_backward): Adjust. Don't set the even thread's stop_step and call stop_waiting before calling end_stepping_range. Instead do that ... (end_stepping_range): ... here. Take an ecs pointer parameter. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 847939b..156b957 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,13 @@ 2014-05-29 Pedro Alves + * infrun.c (process_event_stop_test, handle_step_into_function) + (handle_step_into_function_backward): Adjust. + Don't set the even thread's stop_step and call stop_waiting before + calling end_stepping_range.
