--- Comment #2 from steve at hearnden dot org.uk --- (In reply to Richard Biener from comment #1) > Patches should be sent to gcc-patches@ I was trying to be sure that my understanding was correct before posting my fix. I have since found in the mmix config, a work around for what appears to be this bug, so I am fairly sure I am on the right lines. If someone could validate what the 4th and 5th parameters are meant to be, then I can post my fix.
