ARM patch for branch

ARM patch for branch

[Mark Mitchell]

Momchil Velikov posted a patch which moves a mainline change to the
ARM machine-description to the branch, and thereby fixes 200
test-cases.

I'd like to put this patch in GCC 3.1.1 if you think it's safe.

If you think it's appropriate, would one of you please check in
the patch and then let me know you've done so?

The patch is here:

  http://gcc.gnu.org/ml/gcc-patches/2002-07/msg00866.html

Thanks,

--

Since the patch was actually written by Bernd Schmidt I do think that
it is safe and so I have checked it in to the branch.  Momchil only
mentions half of Bernd's patch but I have taken the liberty of
applying the other half as well (affecting gcc/config/arm/arm.c).  No
regressions were exposed by applying this patch.

Cheers
