--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> 2012-12-13 10:46:00 UTC --- (In reply to comment #5) > As for the PRE issue - we indeed seem to not release SSA temporaries > created by PRE. I'll look into that. Fixed with 2012-12-13 Richard Biener <rguent...@suse.de> * tree-ssa-pre.c (get_representative_for): Adjust dumping. Mark created SSA names for release. (eliminate_bb): Insert only when expr is not NULL.
