tree.h (build_int_cst_wide_type): Export.
2007-01-08 Richard Guenther <rguenther@suse.de>
* tree.h (build_int_cst_wide_type): Export.
* tree.c (build_int_cst_wide_type): New function.
(build_int_cst_wide): Fix comment.
* builtins.c (fold_builtin_object_size): Use build_int_cst
to build -1 or 0 of the correct type. Use fit_double_type
to check for overflow.
* fold-const.c (optimize_bit_field_compare): Use build_int_cst_type
to build the mask.
(decode_field_reference): Likewise.
(all_ones_mask_p): Likewise.
(native_interpret_int): Use build_int_cst_wide_type.
(fold_binary): Use build_int_cst_type to build an all-ones
value.
* stor-layout.c (set_sizetype): Use build_int_cst_wide_type.
java/
* lex.c (do_java_lex): Use build_int_cst_wide_type.
* jcf-parse.c (get_constant): Likewise.
cp/
* cvt.c (cp_convert_to_pointer): Use build_int_cst_type.
ada/
* cuintp.c (build_cst_from_int): Use built_int_cst_type.
* trans.c (gnat_to_gnu): Likewise.
