Reproducible on sparc64-sun-solaris2.9 too.

Comment 3 David S. Miller 2003-07-19 00:34:29 UTC

I checked in a fix written by Richard Henderson to both
the 3.3 branch and the mainline sources.

2003-07-18  Richard Henderson  <rth@redhat.com>
            David S. Miller  <davem@redhat.com>

        * optabs.c (prepare_operand): Fail gracefully instead of abort
        if the predicate doesn't satisfy.
        (gen_cond_trap): Allow prepare_operand to fail.
        Pass correct opnum argument to prepare_operand.
