------- Comment #14 from rguenth at gcc dot gnu dot org 2007-12-12 22:47 ------- Great. That doesn't make too much sense ;) Because the testcase in comment #7 cannot be "optimized" on the tree level, but I see it is wrongly expanded to RTL instead.
Now, the revisions are 103956: make tree-PRE smarter, looking through loads 119760: mem-ssa merge (my favorite) 126149: SCCVN merge nothing expansion related or FE specific. Bah. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33887
