I'd be really glad if you do manage to fix this w/o changing LRA.
Richard has a legitimate point that my proposed change in LRA
prohibiting `...;reg=low_sum; ...mem[reg]` might force LRA to generate
less optimized code or even might make LRA to generate unrecognized
insns `reg = orginal addr` for some ports requiring further fixes in
machine-dependent code of the ports.
