From 13f476282732c81f3e7d7eb6c47c9645725c7451 Mon Sep 17 00:00:00 2001 From: Vadim Yanitskiy Date: Wed, 10 May 2017 01:01:13 +0700 Subject: configure.ac: fix build on systems without SIMD support HAVE_AVX2, HAVE_SSE3 and HAVE_SSE4_1 were never defined if CPU architecture doesn't match the (86*|x86_64*|amd64*) condition.
