The 0->!h alternative should match.
Completely preventing SFmode from being placed in CTR can cause more problems,
but we can do a better job to avoid preferencing that class. I would suggest
trying changing
"=!r,!r,m,f,f,m,!cl,!q,!r,!h,!r,!r"
to
"=!r,!r,m,f,f,m,!*cl,!*q,!r,!*h,!r,!r"
so that the register allocator does not use those special registers for
preferencing decisions. See if that helps.
