* remove trailing commaGravatar Benoit Jacob2015-02-27
|
* Disable Packet2f/2i halfpacket support in NEON.Gravatar Benoit Jacob2015-02-27
| | | | | | I believe that it was erroneously turned on, since Packet2f/2i intrinsics are unimplemented, and code trying to use halfpackets just fails to compile on NEON, as it tries to use the default implementation of pload/pstore and the types don't match.
* bug #955 - Implement a rotating kernel alternative in the 3px4 gebp pathGravatar Benoit Jacob2015-02-18
| | | | | | | | This is substantially faster on ARM, where it's important to minimize the number of loads. This is specific to the case where all packet types are of size 4. I made my best attempt to minimize how dirty this is... opinions welcome. Eventually one could have a generic rotated kernel, but it would take some work to get there. Also, on sandy bridge, in my experience, it's not beneficial (even about 1% slower).

* bug #936, patch 3/3: Properly detect FMA support on ARM (requires VFPv4)Gravatar Benoit Jacob2015-01-30
| | | | | and use it instead of MLA when available, because it's both more accurate, and faster.

| | | | EIGEN_HAS_SINGLE_INSTRUCTION_MADD
* bug #936, patch 1.5/3: rename _FUSED_ macros to _SINGLE_INSTRUCTION_,Gravatar Benoit Jacob2015-01-31
| | | | | | | | | 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.
