--- Comment #3 from Segher Boessenkool <segher at gcc dot gnu.org> --- Author: segher Date: Sat Nov 7 19:44:21 2015 New Revision: 229937 URL: https://gcc.gnu.org/viewcvs?rev=229937&root=gcc&view=rev Log: i386: Use the STC bb-reorder algorithm at -Os (PR67864) For x86, STC still gives better results for optimise-for-size than "simple" does. So use STC at -Os as well. PR rtl-optimization/67864 * common/config/i386/i386-common.c (ix86_option_optimization_table) <OPT_freorder_blocks_algorithm_>: Use REORDER_BLOCKS_ALGORITHM_STC at -Os and up.
