From aa5b5850c0637ad19ab8ffed6437a6e7e9ec033c Mon Sep 17 00:00:00 2001 From: Christian Dywan Date: Mon, 30 Nov 2009 23:21:59 +0100 Subject: [PATCH] Optimize string assignments and comparisons in XBEL loading We can do fast string comparisons in places where we know that strings are not NULL. We can directly assign values to items we create ourselves. --- midori/midori-array.c | 114 ++++++++++++++++++------------------------ 1 file changed, 49 insertions(+), 65 deletions(-) diff --git a/midori/midori-array.c b/midori/midori-array.c index 18aeece0..e769181b 100644 --- a/midori/midori-array.c +++ b/midori/midori-array.c @@ -23,6 +23,8 @@ #include #endif +#define katze_str_equal(str1, str2) !strcmp (str1, str2) + static void katze_xbel_parse_info (KatzeItem* item, xmlNodePtr cur);
