--- Comment #7 from Kazumoto Kojima <kkojima at gcc dot gnu.org> ---

Yes, the comment part says it and it was discussed in #c83
and #c82 of PR55212.  This patch will be a 'micro-degradation',
though it wins CSiBE for the code size at least, even without LRA.

It sounds better and OK for trunk.  Also yes, it looks too invasive
for the release branch.
