--- Comment #8 from Drea Pinski <pinskia at gcc dot gnu.org> --- (In reply to Matthias Kretz (Vir) from comment #4) > Oh, 'fold_builtin_interclass_mathfn' in builtins.cc generates > 'isgreater(abs(x), max)', which is why it's also vectorized as such. > > IMHO, fold_builtin_interclass_mathfn should generate 'or(x, -0) == -inf', > but I assume that would break existing pattern matches for isinf, right? See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94083#c3 and https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66462 about that issue.
