------- Comment #7 from amacleod at redhat dot com 2006-10-02 22:13 ------- Its not that you are expecting too much, just in the wrong place from my point of view :-) Changing the out of ssa algorithm or implementation isnt going to change this code. It requires changing the code out of ssa sees.
insert_backedge_copies() ought to be its own pass as well, as far as Im concerned. Its the very first thing called, and is not related to the rest of what out of ssa does at all. It should be moved out, and we can have an optimization pass just before out-of-ssa which looks for this kind of thing. That can happen when I start adding the pre-passes for register pressure work if no one does it earlier. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27986
