From ecc3135a4a264b66c163ef32e815a99746b81800 Mon Sep 17 00:00:00 2001 From: liuhongt Date: Mon, 24 Aug 2020 20:36:52 +0800 Subject: [PATCH] Retune mask <->integer cost for non-AVX512 micro-architecture. gcc/ChangeLog: PR target/96744 * config/i386/x86-tune-costs.h (struct processor_costs): Increase mask <-> integer cost for non AVX512 target to avoid spill gpr to mask.
