From 32308c8db4af9260cafcb517fe020dff5280f993 Mon Sep 17 00:00:00 2001 From: Segher Boessenkool Date: Tue, 20 Oct 2015 00:03:13 +0200 Subject: mn10300: Use the STC bb-reorder algorithm at -Os For mn10300, STC still gives better results for optimise-for-size than "simple" does. So use STC at -Os as well. 2015-10-19 Segher Boessenkool * common/config/mn10300/mn10300-common.c (mn10300_option_optimization_table) : Use REORDER_BLOCKS_ALGORITHM_STC at -Os and up.
