--- Comment #11 from Richard Biener <rguenth at gcc dot gnu.org> --- Internally we might want to introduce HONOR_FPE_{DIVBYZERO,INEXACT,INVALID,OVERFLOW,UNDERFLOW} so transforms can be appropriately annotated. There might be a difference between preserving and not introducing new, esp. if trapping on the exceptions is enabled (there's related -fdelete-dead-exceptions). HONOR_FPE_ANY might be a good "don't know/care" thing to introduce.
