e3ed13cbd4 Cleanup: Remove special code for Visual Studio 2008. 
Goodbye VC2008, it has been a pleasure (more or less) :D SCons / CMake cleaenup will follow.

866c7fb6e6 Cycles: Add an AVX2 CPU kernel. 
This kernel is compiled with AVX2, FMA3, and BMI compiler flags. At the moment only Intel Haswell benefits from this, but future AMD CPUs will have these instructions as well.

Makes rendering on Haswell CPUs a few percent faster, only benchmarked with clang on OS X though.

Part of my GSoC 2014.

cd5e1ff74e Cycles Refactor: Add SSE Utility code from Embree for cleaner SSE code. 
This makes the code a bit easier to understand, and might come in handy
if we want to reuse more Embree code.

Differential Revision: https://developer.blender.org/D482

Code by Brecht, with fixes by Lockal, Sergey and myself.

f70d966047 Scons: refactor cycles kernel code to avoid building the AVX kernel with 
compilers that don't support it.

CMake still needs to updated to work the same for consistency, but this should
fix the OS X buildbot at least.

de28a4d4b2 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.

9e3ddd70d4 Cycles: Disable SSE41 kernel on 32bit, we don't use intrinsics here anyway. Also disable it for Visual Studio < 2012, broken blendv instruction. 2014-01-14 23:51:59 +01:00

9351ac0d85 Cycles: Skip the compilation of the dedicated SSE2 kernel on x86-64, we can assume SSE2 here, so just re-use the regular one. Saves 500kb in the blender binary.
