We made a lot of progress on it with the patches to 34400, but largest remaining problem is the space that the current representation of def-use and use-def chains requires. I should be able to almost cut this in half if we move to something like a vec rather than a linked list. But this is a big patch and i do not want to start this until stage I. kenny -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26854
