--- Comment #6 from Jeffrey A. Law <law at gcc dot gnu.org> --- And just to follow-up. With the patch that was committed to the trunk, the 30+ targets that were previously failing are now working. A few are still building, but I expect them to succeed. mips* is failing, but I suspect it's the recent allocator changes, not the vectorizer changes causing problems.
