From ad5a332c750550adbd45f474e5936cae65b4fd5e Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 14 Jun 2012 08:36:06 -0400 Subject: [PATCH] reorder exit code to defer stdio flush until after dtors this is required in case dtors use stdio. also remove the old comments; one was cruft from when the code used to be using function pointers and conditional calls, and has little motivation now that we're using weak symbols. the other was just complaining about having to support dtors even though the cost was made essentially zero in the non-use case by the way it's done here. --- src/exit/exit.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/src/exit/exit.c b/src/exit/exit.c index fc291484..03c46ca5 100644 --- a/src/exit/exit.c +++ b/src/exit/exit.c @@ -20,13 +20,10 @@ void exit(int code) /* If more than one thread calls exit, hang until _Exit ends it all */ while (a_swap(&lock, 1)) __syscall(SYS_pause); - /* Only do atexit & stdio flush if they were actually used */ __funcs_on_exit(); - __fflush_on_exit(); - - /* Destructor s**t is kept separate from atexit to avoid bloat */ if (libc.fini) libc.fini(); if (libc.ldso_fini) libc.ldso_fini(); + __fflush_on_exit(); _Exit(code); for(;;); -- 2.25.1
