    I'm sure this makes sense, but a gcc test case would be even better.
    If this can be detected in the gcc test suite it'll be found and
    fixed long before y'all in kernel land get to see it. That's the
    only way to guarantee this never bothers you again.

    H.J., who wrote the code in question, is hopefully looking at why
    this odd code is being generated. Once he's done I can put a
    suitable test case in the gcc test suite.

    Andrew.
