--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
convert(32bit)*integerinfp -> 32bit*32bit widening multiple+converttofp . You
might still end up with 2 conversions but integer multiples rather than fp
multiplies as there is a rounding issue depending on how many bits are used in
the integerinfp are done.
