--- Comment #16 from Richard Biener <rguenth at gcc dot gnu.org> --- Created attachment 37474 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37474&action=edit patch for SSA name management This patch changes SSA name freelist management to keep the freelist sorted and at flush_ssaname_freelist shrink num_ssa_names as much as possible. The goal is to make used SSA names as dense as possible. Does this patch fix the Coremark regression by chance? (I'll note that a proper fix would change the important coalesce cost so it is carried out regardless of SSA name order).
