From 863601c58968a5816ff17722432b5eedc6e13eae Mon Sep 17 00:00:00 2001 From: Johann Date: Thu, 25 Apr 2013 23:26:20 -0700 Subject: Normalize more intrinsic filenames vp9_dequantize_x86 has only sse2 functions. vp9_dct_sse2_intrinsics has no namespace collision and can drop _intrinsics. vp9_idct_mmx.h is unused.
