------- Comment #8 from matz at gcc dot gnu dot org 2009-07-22 15:40 ------- So, the immediate problem is now fixed, but I'd suggest leaving this enhancement request open, in case anybody wants to work on extending the vectorizer to deal with these loop-carried dependencies, because in that case we wouldn't need to dumb down PRE anymore, which would be even better.
