A couple major intentions, mainly to produce better code for avx512: * hide the differences in masking operations - avx/avx2 uses a normal ymm register for masking, while avx512 has separate mask registers * allow reduced vector width operations to be implemented in terms of avx512 code, so that a larger register set and mask registers can be used > Did you notice the errors in the Travis build [1]?

Sorry, had a patch for this ready to go Friday, but we were working through some other issues and I forgot to send it to the list. I’ve done so now. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
