--- Comment #3 from Oleg Endo <olegendo at gcc dot gnu.org> ---
While working on adding some patterns for PR 64345, the issue got even worse. 
The problem in the description is just the tip of the iceberg.  For the time
being a bunch of peephole patterns can be used to limit the damage.  The
peepholes that I've added also seem to improve code when LRA is used.
