Sean Barrett f259bf27e9 VC6: 
support using inline asm for cpuid

YCbCr:
  switch SSE code to constants that match old C;
  create C version that is same as SSE;
  tiny optimization(?) of SSE

later.

Fabian Giesen fb2c841bb8 stb_image: Add more of the SSE2 skeleton. 2014-12-18 07:03:21 -08:00
Fabian Giesen c6a3235995 stb_image: IDCT kernel func ptr in stbi__jpeg 
I want to support SSE2 kernels that auto-detect. If implemented
using globals, this would trigger thread race checkers if stb_image
was used in multiple threads. Just make the kernels be explicitly
per-stbi__jpeg to avoid this.

(This commit is the first step in replacing existing STBI_SIMD
functionality.)

Fabian Giesen 518306517c stb_image: JPEG dequant in decode_block not IDCT. 
Inside decode_block, we're still sparse, and we can use that
sparsity pattern without doing extra work to discover it.
