From 8f0246551c3964eeb16d9c9f39845bd53af8bda8 Mon Sep 17 00:00:00 2001 From: Alex Riesen Date: Thu, 19 Mar 2009 23:27:32 +0100 Subject: [PATCH] Microoptimize strbuf_cmp It can be less object code and may be even faster, even if at the moment there is no callers to take an advantage of that. This implementation can be trivially made inlinable later.
