From 130e7ead87a065faefc7bb03e680c80e04c0a637 Mon Sep 17 00:00:00 2001 From: Adam Jackson Date: Fri, 10 Jun 2011 12:56:51 -0400 Subject: [PATCH] llvmpipe: SSE2 fastpaths for b8g8r8x8 {un,}swizzle Copy-and-paste from the bgra cases. The C paths attempt to avoid copying the 'x' channel, but it's harmless, you might as well. Good for about 5% in glxgears (740 to 780 fps).
