Description Gael Guennebaud 2018-10-12 07:29:31 UTC
The correct fix would be to merge all plog implementations following SSE/AVX versions.
Comment 2 Christoph Hertzberg 2018-10-12 08:11:07 UTC
The best solution would be to fix Bug 692 (Meta-Packets).
Comment 3 Gael Guennebaud 2018-11-26 14:13:10 UTC

and I've started to merge the different implementations. Done for plog on SSE/AVX/NEON. MSA should be easy. AVX512 will require a more involved unified API for comparisons and bit masking.
