[llvm-commits] r119002 breaks snow.c from FFmpeg

[İsmail Dönmez]

Hi;

According to
http://fate.ffmpeg.org/x86_64-apple-darwin10-clang/20101114104032 clang has
regressed wrt. ffmpeg regtesting. A quick search showed that r119002 broke
snow.c . I attached preprocessed source code for snow.c. Here is the
difference between working & non-working snow.c assemblies :

--- snow-working.s 2010-11-14 22:59:28.000000000 +0200
+++ snow-broken.s 2010-11-14 23:29:42.000000000 +0200
