Revision de28a4d by Thomas Dinges (master) January 16, 2014, 16:04 (GMT) |
Cycles: Add an AVX kernel for CPU rendering. * AVX is available on Intel Sandy Bridge and newer and AMD Bulldozer and newer. * We don't use dedicated AVX intrinsics yet, but gcc auto vectorization gives a 3% performance improvement for Caminandes. Tested on an i5-3570, Linux x64. * No change for Windows yet, MSVC 2008 does not support AVX. Reviewed by: brecht Differential Revision: https://developer.blender.org/D216 |
