expr.c (get_inner_reference): Use sbitsizetype for type sizes.
* expr.c (get_inner_reference): Use sbitsizetype for type sizes.
* fold-const.c (size_int): Replace with
(size_int_wide).
(make_bit_field_ref): Use bitsize_int for bit position.
* stor-layout.c (sizetype): Delete.
(sizetype_tab, sbitsizetype, ubitsizetype): Declare.
(layout_record, layout_union, layout_type):
Use bitsize_int for bit size.
(set_sizetype): New function.
(make_signed_type, make_unsigned_type): Use it.
* c-decl.c (init_decl_processing): Likewise.
* tree.h (size_int): Don't delcare, #define.
(size_int_wide, sizetype_tab, sbitsize, ubitsize): Declare.
(set_sizetype): Declare.
(bitsize_int, size_int_2, BITS_PER_UNIT_LOG, sizetype, bitsizetype):
Define.
* c-typeck.c (c_sizeof, c_sizeof_nowarn, c_size_in_bytes):
Convert result to sizetype.
(really_start_incremental_init, push_init_level):
Set type of constructor_bit_index to sbitsizetype.
(push_init_level): Use unsigned arithmetic to determine padding.
(output_init_element): Likewise.
