Date: Sun, 11 Apr 2004 13:09:44 +0200 From: Stephane Marchesin Subject: [SDL] [Patch] inlining memcpy functions I (finally) did some benchmarking of the misc mmx & sse blitting functions, and found a little bottleneck in the memcpy ones : you get ~10% more performance on small surface blitting if you inline them.
