From 585a46a2d01d25181926329f258f1d1374f93e99 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Tue, 12 Apr 2016 16:49:32 +0100 Subject: Eliminate immediate_quit This finally gets rid of immediate_quit (and surrounding infrustruture), as nothing sets it anymore. gdb_call_async_signal_handler was only necessary in order to handle immediate_quit. We can just call mark_async_signal_handler directly on all hosts now. In turn, we can clean up mingw-hdep.c's gdb_select a bit, as sigint_event / sigint_handler is no longer needed. gdb/ChangeLog: 2016-04-12 Pedro Alves * defs.h: Update comments on SIGINT handling. (immediate_quit): Delete declaration. * event-loop.c (call_async_signal_handler): Delete. * event-loop.h (call_async_signal_handler): Delete declaration. (mark_async_signal_handler): Update comments. (gdb_call_async_signal_handler): Delete declaration. * event-top.c (handle_sigint): Call mark_async_signal_handler instead of gdb_call_async_signal_handler. * exceptions.c (prepare_to_throw_exception): Remove reference to immediate_quit. (exception_fprintf): Remove comments about immediate_quit. * mingw-hdep.c (sigint_event, sigint_handler): Delete. (gdb_select): Don't wait on sigint_event. (gdb_call_async_signal_handler): Delete. (_initialize_mingw_hdep): Delete. * posix-hdep.c (gdb_call_async_signal_handler): Delete. * utils.c (immediate_quit): Delete. --- gdb/utils.c | 13 ------------- 1 file changed, 13 deletions(-) (limited to 'gdb/utils.c') diff --git a/gdb/utils.c b/gdb/utils.c index bc62218..db5104d 100644 --- a/gdb/utils.c +++ b/gdb/utils.c @@ -109,19 +109,6 @@ static int debug_timestamp = 0; int job_control; -/* Nonzero means quit immediately if Control-C is typed now, rather - than waiting until QUIT is executed.
