Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- This is invalid. You need -ffp-contract=off to get the same behavior for the constant folding as for the instructions emitted. Basically the same behavior would happen on PowerPC and on x86_64 (with -mfma).
