Subject: Makefile.in (c-lang.o): Depends on langhooks-def.h.

	* Makefile.in (c-lang.o): Depends on langhooks-def.h.
	(expr.o, varasm.o): Depends on langhooks.h.
	* c-common.c (c_safe_from_p): Always declare.
	(c_expand_expr): Refine when declared.
	* c-lang.c (c-common.h): Now include.
	(LANG_HOOKS_SAFE_FROM_P): Define new hook.
	(c_init): Don't set lang_safe_from_expr.
	* expr.c (langhooks.h): Now include.
	(lang_safe_from_p): No longer define.
	(safe_from_p): Use lang hook.
	(expand_expr): Set IGNORE if VOID_TYPE result of VIEW_CONVERT_EXPR too.
	(expand_expr, case VIEW_CONVERT_EXPR): Pass ro_modifier down.
	* expr.h (lang_expand_constant, lang_safe_from_p): Delete.
	* langhooks-def.h (lhd_return_tree, lhd_safe_from_p): New decls.
	(LANG_HOOKS_EXPAND_CONSTANT, LANG_HOOKS_SAFE_FROM_P): New hooks.
	* langhooks.c (lhd_return_tree, lhd_safe_from_p): New functions.
	* langhooks.h (struct lang_hooks): New fields expand_constant
	and safe_from_p.
	* output.h (output_constant): Size arg is HOST_WIDE_INT.
	* stmt.c (expand_decl_init): No longer need to expand constant
	for CONST_DECL.
	* stor-layout.c (put_pending_size): Don't check for SAVE_EXPR.
	* toplev.c (lang_expand_constant): Delete var.
	* tree.c (save_expr): Don't put another SAVE_EXPR around simple
	operations on SAVE_EXPR.
	* varasm.c (langhooks.h): Now include.
	(compare_constant_1): Use lang_hooks, not lang_expand_constant.
	(record_constant_1, output_addressed_constants): Likewise.
	(initializer_constant_valid_p, output_constant): Likewise.
	(output_constant_def): Process no-defer of string constant.
	(output_addressed_constants, case ADDR_EXPR): Use handled_component_p.
	(output_constant): Strip more conversions.
	Track our size and pad for the rest.
	(array_size_for_constructor): Remove code for non-byte STRING_CST.
	(output_constructor): SIZE now HOST_WIDE_INT.
	* cp/Make-lang.in (cp-lang.o): Depends on c-common.h.
	* cp/cp-lang.c (c-common.h): Include.
	(LANG_HOOKS_EXPAND_CONSTANT, LANG_HOOKS_SAFE_FROM_P): New hooks.
	* cp/decl.c (cxx_init_decl_processing): Don't set lang_safe_from_p.
	* cp/expr.c (init_cplus_expand): Don't set lang_expand_constant.
