I'm not sure whether it can help you in this particular case, but you
might have a look at how this is done in the SH target (trunk version,
not 4.5.2 snapshot) and take PR 51244 into account.  Currently the SH
target suffers from a similar problem.  The patch from PR 51244 fixes
the issue.  In the SH case it helped looking at what the combine pass is
trying to do.

Hope it's useful.

Cheers,
Oleg
