Changeset:   9fb7506db078
User:        jaopaulolc
Date:        2019-08-09 21:59:26+00:00
Summary:     Fix offset argument of ploadu/pstoreu for Altivec

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.

Changeset:   71ea03af39b8
User:        jaopaulolc
Date:        2019-08-09 22:02:55+00:00
Summary:     Fix packed load/store for PowerPC's VSX

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.

Changeset:   d7106a0f89e8
User:        jaopaulolc

Summary:     Add missing pcmp_XX methods for double/Packet2d

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.
