From deb85ab44dbe784ba6174b8cf376d35aeacbe309 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 9 Sep 2015 06:59:45 +0000 Subject: [PATCH] remove unused (and invalid) C version of sigsetjmp originally, the comment in this code was correct and it would likely work if the compiler generated a tail call to setjmp. however, commit 583e55122e767b1586286a0d9c35e2a4027998ab redesigned sigsetjmp and siglongjmp such that the old C implementation (which was not intended to be used) is not even conceptually correct. remove it in the interest of avoiding confusion when porting to new archs. --- src/signal/sigsetjmp.c | 17 ----------------- 1 file changed, 17 deletions(-) diff --git a/src/signal/sigsetjmp.c b/src/signal/sigsetjmp.c index 1bbe1a0b..e69de29b 100644 --- a/src/signal/sigsetjmp.c +++ b/src/signal/sigsetjmp.c @@ -1,17 +0,0 @@ -#include -#include -#include "libc.h" - -/* !!!
