Note from that bug:
A proposed fix is here:
http://gcc.gnu.org/ml/gcc-patches/2004-09/msg02193.html
By moving three-linked combine pass in front of two-linked pass, combiner has
considerably more freedom to simplify instructions.
Adding this to 17652 since the pending patch was considered too risky for stage3
(http://gcc.gnu.org/ml/gcc-patches/2004-09/msg02241.html)
