807793ec3b Fix uninitialized var warning. The compiler was clearing the register anyway, so this does not change resulting code 2015-05-15 11:15:53 -04:00

33669348c4 Disable Packet2f/2i halfpacket support in NEON.
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.

9bd8a4bab5 bug #955 - Implement a rotating kernel alternative in the 3px4 gebp path
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).

98604576d1 Merged in chtz/eigen-indexconversion (pull request PR-92)
bug #877, bug #572: Get rid of Index conversion warnings, summary of changes:

- Introduce a global typedef Eigen::Index making Eigen::DenseIndex and AnyExpr<>::Index deprecated (default is std::ptrdiff_t).

 - Eigen::Index is used throughout the API to represent indices, offsets, and sizes.

 - Classes storing an array of indices uses the type StorageIndex to store them. This is a template parameter of the class. Default is int.

 - Methods that *explicitly* set or return an element of such an array take or return a StorageIndex type. In all other cases, the Index type is used.

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.

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.
