Subject: [patch 0/2] use asm() for atomic_{read|set}
Date: Wed, 15 Aug 2007 00:38:45 +0200 [thread overview]
Message-ID: <20070814223845.518697567@breakpoint.cc> (raw)
I converted i386+x86-64. Compiled, booted and played for a while. The
description of both patches contains the file size of four kernel builds:
- "normal" is 28e8351ac22de25034e048c680014ad824323c65 as it
- "inline asm" is with this patch
- "inline volatile" is *(volatile int *)&(v)->counter as a static inline
function
- "volatile" is *(volatile int *)&(v)->counter as a #define macro
I hope I don't encourage anyone to use macros over inline functions.
Sebastian
