Hi Brecht, great work, thank you! On Linux I get a nice speedup. :) Windows fails to compile for me though (vc2008).
Linking library ==> 'bf_intern_cycles_sse2.lib' kernel_sse3.cpp d:\blender_dev\code\trunk\intern\cycles\kernel\svm\svm_noise.h(38) : fatal error C1001: Internal compile error. (Compilerdatei "f:\dd\vctools\compiler\utc\src\p2\main.c[0x00000000604E0000:0x00 000000604E0000]", Zeile 182) Any idea? I tried a full clean build already.
