------- Comment #24 from steven at gcc dot gnu dot org  2008-12-01 22:00 -------
Created an attachment (id=16803)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=16803&action=view)
patch to implement code hoisting in tree-ssa-pre.c

This passes bootstrap+testing on ia64-linux and amd64-linux.  It causes a few
vectorizer failures (4 on ia64) that I have not analyzed yet.
