From 1882cf1c9d68e0c325c89f0bdf368b47206f19e0 Mon Sep 17 00:00:00 2001 From: Thiago Macieira Date: Thu, 29 Dec 2011 22:44:16 -0200 Subject: Add detection of AVX and AVX2 support in the compiler. Intel CC 12.1 supports AVX2 but only with -march=core-avx2. The -mavx2 option produces a warning. GCC 4.6 does not recognise any option. GCC 4.7 recognises both -mavx2 and -march=core-avx2 so let's use the latter for now. We may need to change to -mavx2 when there's an AMD processor that supports AVX2 too.
