From 6ac1730f7db86f0a92d4de0f2b4ca9cd124080fe Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Sun, 16 Sep 2018 16:06:10 +0100 Subject: tools/power/x86: Enable compiler optimisations and Fortify by default Compiling without optimisations is silly, especially since some warnings depend on the optimiser. Use -O2. Fortify adds warnings for unchecked I/O (among other things), which seems to be a good idea for user-space code. Enable that too.
