Thanks for looking to this. No bootstrap unfortunately, but I can regression-test it for cris-elf, which should be sufficient. Well, I'm quite certain you too know exactly the steps ;-) but I guess since I have a baseline and a setup... Let me just suggest changing the "... == 0" to "... == NULL_RTX" in the last part of the patch. To incentivise, I'll test that. :) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45656
