* First part of a big refactoring of alignment control to enable the handling ↵Gravatar Gael Guennebaud2015-08-06
| | | | | | | | | of arbitrarily aligned buffers. It includes: - AlignedBit flag is deprecated. Alignment is now specified by the evaluator through the 'Alignment' enum, e.g., evaluator<Xpr>::Alignment. Its value is in Bytes. - Add several enums to specify alignment: Aligned8, Aligned16, Aligned32, Aligned64, Aligned128. AlignedMax corresponds to EIGEN_MAX_ALIGN_BYTES. Such enums are used to define the above Alignment value, and as the 'Options' template parameter of Map<> and Ref<>. - The Aligned enum is now deprecated. It is now an alias for Aligned16. - Currently, traits<Matrix<>>, traits<Array<>>, traits<Ref<>>, traits<Map<>>, and traits<Block<>> also expose the Alignment enum.

| * Reimplement the selection between rotating and non-rotating kernelsGravatar Benoit Jacob2015-02-27
| | | | | | | | | | | | using templates instead of macros and if()'s. That was needed to fix the build of unit tests on ARM, which I had broken. My bad for not testing earlier.
| * Replace a static assert by a runtime one, fixes the build of unit tests on ARMGravatar Benoit Jacob2015-02-27
|/ | | | | Also safely assert in the non-implemented path that should never be taken in practice, and would return wrong results.
* 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).

* Created the ptranspose packet primitive that can transpose an array of N ↵Gravatar Benoit Steiner2014-03-26

* Revert previous change and introduce a new workaround regarding gcc ↵Gravatar Gael Guennebaud2014-03-20
| | | | | | | generating a shufps instruction instead of the more efficient pshufd instruction. The trick consists in introducing a new pload1 function to be used in low level product kernels for which bug #203 does not apply. Indeed, it turned out that using inline assembly prevents gcc of doing a good job at instructtion reordering.
