builtins.c (fold_builtin_int_roundingfn): Use fit_double_type.
2007-01-08 Richard Guenther <rguenther@suse.de>
* builtins.c (fold_builtin_int_roundingfn): Use fit_double_type.
* tree.c (build_int_cst_type): Likewise.
(size_in_bytes): Don't call force_fit_type on the result.
(int_fits_type_p): Use fit_double_type.
* fold-const.c (fit_double_type): New function.
(force_fit_type): Use it.
* tree.h (fit_double_type): Export.
