--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Perhaps we should just add (void) casts before those calls. It is fine that those builtins have no effects with -ffast-math, they do have effects without it, and I'm not sure if we want to conditionalize those on #ifndef __NO_TRAPPING_MATH__ or whatever would be the right macro.
