--- Comment #4 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Ha.  Our comments crossed in the ether last night and I didn't see the bugzilla
mid-air collision note until just now.

The requested optimization is invalid inless we can prove that the scores array
can't overlap with the input array.  Robin and I looked at this a while back
:-)

The only sensible path forward for the optimization would be to version the
code based on the aliasing properties at runtime.   That felt like pie in the
sky to me.
