[xiph-commits] r11680 - branches/theora-playtime/lib/x86_32_vs

[illiminable at svn.xiph.org]

Author: illiminable
Date: 2006-06-29 16:26:58 -0700 (Thu, 29 Jun 2006)
New Revision: 11680

Modified:
   branches/theora-playtime/lib/x86_32_vs/idct_sse2.c
Log:
* dequant_slow sse2 faster than C (could be deceptive since it's called from the middle of a C function, since the outer function hasn't been written in sse2 yet) : Best case 298 vs 362
