I've patched my gcc-3.4.0 and gcc-3.4.1 trees to fix this.  The
problem was that the subsi3 pattern allows a label-ref to be
subtracced from a general memory operand, something that is illegal
for ColdFire, but legal for 68k.

Could you try building gcc-3.4.0/gcc-3.4.1 from my CVS server and
testing them again?  If that passes, then I'll submit a patch to mainline.

Thanks!
