From 5cc187215681c2fc1563ad5136c389249aa3f70e Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 17 Jul 2014 21:37:10 -0400 Subject: [PATCH] remove useless infinite loop from end of exit function this was originally added as a cheap but portable way to quell warnings about reaching the end of a function that does not return, but since _Exit is marked _Noreturn, it's not needed. removing it makes the call to _Exit into a tail call and shaves off a few bytes of code from minimal static programs. --- src/exit/exit.c | 1 - 1 file changed, 1 deletion(-) diff --git a/src/exit/exit.c b/src/exit/exit.c index 27fb3e29..163d8f1b 100644 --- a/src/exit/exit.c +++ b/src/exit/exit.c @@ -31,5 +31,4 @@ _Noreturn void exit(int code) __stdio_exit(); _Exit(code); - for(;;); } -- 2.25.1
