--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Yeah, I believe it is safe in this case, but we would need the info whether the
conversion is ok or not already during the tailc pass and on many targets such
a conversion is not ok (e.g. if the target says that the value is zero-extended
into 64-bits or sign-extended, or 32-bit and 64-bit returned in different
register, whatever).
The question is if the existing target hooks are sufficient to query this or if
we need a new target hook.
