Re: [PATCH] Enable push_fpscr. pop_fpscr for SH2E

Ah, yes, indeed, I had misunderstood the logic in push_regs().  Still,
I don't see how calc_live_regs() can possibly mark fpscr as used in
SH2e or SH3e.  Anyway, there's no reason to not expose the patterns
since they *are* available on SH2e, so...  Please check it in, if you
can, or post the patch again letting me know you need someone else to
check it in for you (I ask you to post it again just so that someone
looking for the patch in gcc-patches, two years from now, finds it
posted at a date similar to that in the ChangeLog, not half a year
before :-).  Thanks, and sorry about the long delay!
