	gcc            : ChangeLog calls.c explow.c expr.c integrate.c 
	                 langhooks-def.h langhooks.c langhooks.h 
	                 old-tree-inline.c tree-inline.c tree.h 
	gcc/cp         : ChangeLog call.c cp-lang.c cp-simplify.c 
	                 cp-tree.h except.c tree.c 

Log message:
	* tree.h (CALL_EXPR_HAS_RETURN_SLOT_ADDR): New macro.
	* calls.c (expand_call): Handle it.
	* tree-inline.c (struct inline_data): Remove target_exprs field.
	(optimize_inline_calls): Don't initialize it.
	(expand_call_inline): Don't modify it.  Handle
	CALL_EXPR_HAS_RETURN_SLOT_ADDR.
	(declare_return_variable): Take return slot addr.
	* langhooks.h (copy_res_decl_for_inlining): Change target_exprs parm
	to return_slot_addr.
	* langhooks-def.h, langhooks.c: Adjust.
	* explow.c (maybe_set_unchanging): Don't set RTX_UNCHANGING_P for
	a decl with no DECL_INITIAL.
	
	* expr.c (expand_expr): Don't discard the target of a call which
	returns in memory.
	
	PR c++/8461, c++/8625
	* integrate.c (copy_decl_for_inlining): Handle explicit invisible
	references.
	* tree-inline.c (initialize_inlined_parameters): Likewise.
	
	cp/
	* semantics.c (simplify_aggr_init_exprs_r): Also prepend the
	return slot for normal functions.  Set CALL_EXPR_HAS_RETURN_SLOT_ADDR.
	* tree.c (build_cplus_new): If the type isn't TREE_ADDRESSABLE,
	don't bother with an AGGR_INIT_EXPR.
	(cp_copy_res_decl_for_inlining): If the type isn't TREE_ADDRESSABLE,
	just generate a new decl normally.  Take return slot parm.
	* cp-tree.h: Adjust prototype.
	
	PR c++/8461, c++/8625
	* call.c (convert_for_arg_passing): Don't mess with error_mark_node.
	(cp_convert_parm_for_inlining): Remove.
	* cp-lang.c (LANG_HOOKS_TREE_INLINING_CONVERT_PARM_FOR_INLINING):
	Remove.
	* cp-tree.h (ADDR_IS_INVISIREF): Remove.
	* except.c (stabilize_throw_expr): Remove ADDR_IS_INVISIREF code.
