From 7f1061938415f0d93d7ee6040e49236d2e050627 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Tue, 12 Dec 2017 14:31:55 +0100 Subject: [PATCH] x86emul: build SIMD tests with -Os Specifically in the context of putting together subsequent patches I've noticed that together with the touch() macro using -Os further increases the chances of the compiler using memory operands for the instructions we actually care to test.
