        PR middle-end/28796
        * builtins.c (fold_builtin_classify): Use HONOR_INFINITIES
        and HONOR_NANS instead of MODE_HAS_INFINITIES and MODE_HAS_NANS
        for deciding optimizations in consistency with fold-const.c
        (fold_builtin_unordered_cmp): Likewise.

        * gcc.dg/pr28796-1.c: New testcase.
        * gcc.dg/pr28796-1.c: Likewise.
