------- Comment #33 from rakdver at gcc dot gnu dot org 2006-04-12 12:20 ------- Created an attachment (id=11248) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=11248&action=view) Patch to speed up update_ssa
This patch makes update_ssa significantly faster in cases like this (when update_ssa is called often), by ensuring that we do not perform unnecessary expensive tasks (walking all statements or ssa names) each time update_ssa is called. Several more improvements are possible, especially in the phi insertion phase. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26830
