From e249b1a313b2e7925a12416af8172632588e77cd Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Thu, 27 Aug 2020 21:07:57 +0200 Subject: arch/x86: x86_64 implies SSE2 support Enable SSE2 (and SSE) when compiling for x86_64. Compilers often assume SSE2 is present and enabled when targeting x86_64. This fixes: - lzma decompression code is compiled with the -Ofast flag - 'everything' when compiling with clang. This mostly affects qemu targets, which did not have this flag selected yet. TESTED on qemu.
