* | bug #936, patch 1.5/3: rename _FUSED_ macros to _SINGLE_INSTRUCTION_, | 2015-01-31 | |
| | | | | | | | | | because this is what they are about. "Fused" means "no intermediate rounding between the mul and the add, only one rounding at the end". Instead, what we are concerned about here is whether a temporary register is needed, i.e. whether the MUL and ADD are separate instructions. Concretely, on ARM NEON, a single-instruction mul-add is always available: VMLA. But a true fused mul-add is only available on VFPv4: VFMA. | ||

| | | | | | | | replaced _mm_prefetch in GeneralBlockPanelKernel.h, with ei_prefetch() 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. | ||

| | | | | | | | | hackish workarounds as gcc on ARM (both CodeSourcery 4.4.1 used and experimental 4.5) fail to ensure proper alignment with __attribute__((aligned(16))). This has to be fixed upstream to remove the workarounds. |
