From: Tim Rowley Date: Wed, 1 Jun 2016 02:01:40 +0000 (-0600) Subject: swr: [rasterizer] add support for building avx512 version X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b6d2c9685154a6bed5c42d90af39213e9c274b59;p=mesa.git swr: [rasterizer] add support for building avx512 version Currently, most code paths between AVX2 and AVX512 are identical (see changes to knobs.h).
