0f3fed2970 OS X linker does not like empty compilation unit by itself in a library. Scons creates one library (.a) per kernel. This fixes that 2014-01-14 22:48:31 +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.

e3a79258d1 Cycles: test code for sse 4.1 kernel and alignment for some vector types. 
This is mostly work towards enabling the __KERNEL_SSE__ option to start using
SIMD operations for vector math operations. This 4.1 kernel performes about 8%
faster with that option but overall is still slower than without the option.

WITH_CYCLES_OPTIMIZED_KERNEL_SSE41 is the cmake flag for testing this kernel.

Alignment of int3, int4, float3, float4 to 16 bytes seems to give a slight 1-2%
speedup on tested systems with the current kernel already, so is enabled now.
