From: Pedro Alves Date: Thu, 27 Mar 2014 18:42:53 +0000 (+0000) Subject: infrun.c: stop_stepping -> stop_waiting. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=22bcd14b34126004346fa3226532dd2c1f3a9790;p=binutils-gdb.git infrun.c: stop_stepping -> stop_waiting. stop_stepping is called even when we weren't stepping. It's job really is: static void stop_waiting (struct execution_control_state *ecs) { ... /* Let callers know we don't want to wait for the inferior anymore. */ ecs->wait_some_more = 0; } So rename it for clarity. gdb/ 2014-05-29 Pedro Alves * infrun.c (stop_stepping): Rename to ...
