Given that there won't be any HFmode arithmetic patterns,
I don't see how that could happen. At minimum, optabs.c
will try to promote to SFmode for that, even thought that
might not necessarily be correct (HFmode will have a
larger exponent than SFmode).
I think all the mode narrowing stuff happens at the tree
level though, so we should be safe.
