  • 5ef95fabee bug #936, patch 3/3: Properly detect FMA support on ARM (requires VFPv4) and use it instead of MLA when available, because it's both more accurate, and faster. Benoit Jacob 2015-01-30 17:45:03 -05:00
  • 0f21613698 bug #936, patch 2/3: Remove EIGEN_VECTORIZE_FMA, was redundant with EIGEN_HAS_SINGLE_INSTRUCTION_MADD Benoit Jacob 2015-01-30 17:44:26 -05:00
  • 340b8afb14 bug #936, patch 1.5/3: rename _FUSED_ macros to _SINGLE_INSTRUCTION_, 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. Benoit Jacob 2015-01-31 14:15:57 -05:00
  • 9f99f61e69 bug #936, patch 1/3: some cleanup and renaming for consistency. Benoit Jacob 2015-01-30 17:43:56 -05:00
  • 759bd92a85 bug #935: Add asm comments in GEBP kernels to work around a bug in both GCC and Clang on ARM/NEON, whereby they spill registers, severely harming performance. The reason why the asm comments make a difference is that they prevent the compiler from reordering code across these boundaries, which has the effect of extending the lifetime of local variables and increasing register pressure on this register-tight code.
