From 0125fb63521b58780c41d9ded78ce175c8c5a7e0 Mon Sep 17 00:00:00 2001 From: Warner Losh Date: Wed, 5 Sep 2018 20:02:23 +0000 Subject: [PATCH] Be a little conservative about when to force size optimizations. Reports have come in that there's issue with powerpc and sparc64 since we've switched to using -Oz / -Os. We don't strictly need them for !x86, so be conservative about when we enable them.
