Makefile.in (c-decl.o): Depend on rtl.h and expr.h.
* Makefile.in (c-decl.o): Depend on rtl.h and expr.h.
* alias.c (struct alias_entry): alias_set is HOST_WIDE_INT.
(REG_BASE_VALUE): Remove unneeded cast to unsigned.
(get_alias_set_entry): ALIAS_SET arg is HOST_WIDE_INT.
(find_base_decl): New function, from c_find_base_decl in c-common.c.
(new_alias_set): Moved from tree.c; return is HOST_WIDE_INT.
(get_alias_set): Likewise.
Major rework to do more things and allow language-specific code
to just handle special-cases.
(record_alias_subset): Args are HOST_WIDE_INT.
(record_component_alias): Local vars are HOST_WIDE_INT.
Don't handle COMPLEX_EXPR.
(get_varargs_alias_set): Moved from builtins.c.
(get_frame_alias_set): New function.
* builtins.c (expand_builtin_return_address): Use frame alias set.
(expand_builtin_setjmp, expand_builtin_longjmp): Use alias set
for setjmp buffer.

(c_get_alias_set): Remove many cases and rework to just handle
C-specific cases.
* c-common.h (c_get_alias_set): Returns HOST_WIDE_INT.
* c-decl.c (rtl.h, expr.h): Now included.
(init_decl_processing): Call record_component_aliases on array types.
(grokdeclarator): Likewise.
Set TREE_ADDRESSABLE for all fields that are not bitfields.
* c-typeck.c (common_type): Call record_component_aliases for array.

(compute_argument_addresses, expand_call): Likewise.
* explow.c (set_mem_attributes): New function.
(stabilize): Use MEM_COPY_ATTRIBUTES and force_reg.
* expr.c (struct move_by_pieces): Remove {to,from}_{struct,readonly}.
LEN and OFFSET now HOST_WIDE_INT.
(clear_by_pieces): Similar changes.
(move_by_pieces): LEN now HOST_WIDE_INT; don't set deleted fields.
(move_by_pieces_ninsns): Now returns unsigned HOST_WIDE_INT.
