Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> --- Yeah, what we lack here is some kind of FP classification [IPA] "propagation" and SSA on-the-side info so folding patterns could query fp_class_not (@0, FP_SNAN|FP_SIGNED_ZERO). There's unused room for FP SSA names where SSA_NAME_{PTR,RANGE}_INFO is stored. This is mentioned in some other bugs as well. But this bug as-is is invalid.
