From a9ae9abc43a859e8539998b5a55a8bb5cbccc637 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Sun, 30 Oct 2005 15:02:12 -0800 Subject: [PATCH] [PATCH] lib/string.c cleanup: remove pointless register keyword Removes a few pointless register keywords. register is merely a compiler hint that access to the variable should be optimized, but gcc (3.3.6 in my case) generates the exact same code with and without the keyword, and even if gcc did something different with register present I think it is doubtful we would want to optimize access to these variables - especially since this is generic library code and there are supposed to be optimized versions in asm/ for anything that really matters speed wise. (akpm: iirc, keyword register is a gcc no-op unless using -O0) Signed-off-by: Jesper Juhl Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- lib/string.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/lib/string.c b/lib/string.c index 54eb3f81f85ef..542829742c85f 100644 --- a/lib/string.c +++ b/lib/string.c @@ -219,7 +219,7 @@ EXPORT_SYMBOL(strlcat); #undef strcmp int strcmp(const char *cs, const char *ct) { - register signed char __res; + signed char __res; while (1) { if ((__res = *cs - *ct++) != 0 || !*cs++) @@ -239,7 +239,7 @@ EXPORT_SYMBOL(strcmp); */ int strncmp(const char *cs, const char *ct, size_t count) { - register signed char __res = 0; + signed char __res = 0; while (count) { if ((__res = *cs - *ct++) != 0 || !*cs++) -- 2.39.5
