Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|normal |enhancement Last reconfirmed|2019-09-12 00:00:00 |2021-12-12 --- 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.
