* replaced _mm_prefetch in GeneralBlockPanelKernel.h, with ei_prefetch() ↵Gravatar oem2010-04-24
| | | | | | | | inline function. Implemented NEON and AltiVec versions, copied SSE version over from GeneralBlockPanelKernel.h. Also in GCC case (or rather !_MSC_VER) it's implemented using __builtin_prefetch(). NEON managed to give a small but welcome boost, 0.88GFLOPS -> 0.91GFLOPS.
