Hi Richard,

/sloth/delay/tbox/cvs-gcc/gcc/gcc/libgcc2.c: In function `__divdi3':
/sloth/delay/tbox/cvs-gcc/gcc/gcc/libgcc2.c:747: Unrecognizable insn:
(insn 725 722 195 (set (reg:SI 339)
        (and:SI (reg/v:SI 125)
            (const_int 65535 [0xffff]))) -1 (nil)
    (nil))

Something's not checking that insns are valid after making
substitutions.  This insn is invalid because it needs an extra
CLOBBER.
