I'm not able to reproduce the ICE on my side with or without -mvectorize-with-neon-quad with this patch. I don't know if configuring to build for cortex-a9 has anything to do with this because that's what is on my side and you don't seem to have it configured to build for a cpu with NEON. Does the ICE happen if you specify -mcpu=cortex-a9 on the command-line? Also, are you using trunk's HEAD?
