Alexander Monakov <amonakov at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED CC| |amonakov at gcc dot gnu.org Resolution|--- |INVALID --- Comment #2 from Alexander Monakov <amonakov at gcc dot gnu.org> --- fcmov can only raise an x87 fpu exception on x87 stack underflow, which cannot happen here. Even if it did raise FE_INVALID for SNaNs, note that GCC does not support SNaNs by default; -fsignaling-nans can be specified to request that, but note that documentation says the support is incomplete. No bug here afaict.
