| * Add missing pcmp_XX methods for double/Packet2dGravatar João P. L. de Carvalho2019-08-14
| | | | | | | | This actually fixes an issue in unit-test packetmath_2 with pcmp_eq when it is compiled with clang. When pcmp_eq(Packet4f,Packet4f) is used instead of pcmp_eq(Packet2d,Packet2d), the unit-test does not pass due to NaN on ref vector.
* | Implement vectorized versions of log1p and expm1 in Eigen using Kahan's ↵Gravatar Rasmus Munk Larsen2019-08-12
| | | | | | | | | | | | | | | | | | | | | | | | formulas, and change the scalar implementations to properly handle infinite arguments. Depending on instruction set, significant speedups are observed for the vectorized path: log1p wall time is reduced 60-93% (2.5x - 15x speedup) expm1 wall time is reduced 0-85% (1x - 7x speedup) The scalar path is slower by 20-30% due to the extra branch needed to handle +infinity correctly.

| * Fix packed load/store for PowerPC's VSXGravatar João P. L. de Carvalho2019-08-09
| | | | | | | | | | | | | | | | The vec_vsx_ld/vec_vsx_st builtins were wrongly used for aligned load/store. In fact, they perform unaligned memory access and, even when the address is 16-byte aligned, they are much slower (at least 2x) than their aligned counterparts. For double/Packet2d vec_xl/vec_xst should be prefered over vec_ld/vec_st, although the latter works when casted to float/Packet4f. Silencing some weird warning with throw but some GCC versions. Such warning are not thrown by Clang.
| * Fix offset argument of ploadu/pstoreu for AltivecGravatar João P. L. de Carvalho2019-08-09
| | | | | | | | | | | | | | | | | | | | If no offset is given, them it should be zero. Also passes full address to vec_vsx_ld/st builtins. Removes userless _EIGEN_ALIGNED_PTR & _EIGEN_MASK_ALIGNMENT. Removes unnecessary casts.
