re PR middle-end/28796 (__builtin_nan() and __builtin_unordered() inconsistent)

2006-10-24  Richard Guenther  <rguenther@suse.de>

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.
