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.

0f21613698 bug #936, patch 2/3: Remove EIGEN_VECTORIZE_FMA, was redundant with EIGEN_HAS_SINGLE_INSTRUCTION_MADD 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.

84aaa03182 Addendum to bug #859: pexp(NaN) for double did not return NaN, also, plog(NaN) did not return NaN.
