	gcc            : ChangeLog calls.c expr.c expr.h 

Log message:
	* calls.c (store_one_arg): Revert 1999-02-16 change.  Revert
	2000-12-17 change.  Pass EXPAND_STACK_PARM to expand_expr.
	* expr.h (enum expand_modifier): Define EXPAND_STACK_PARM.
	(enum block_op_methods): Reorder for better store_expr optimization.
	* expr.c (store_expr): Test bit 1 of "want_value" for call param
	stores, test bit 0 for original want_value meaning.  Pass
	BLOCK_OP_CALL_PARM to emit_block_move when bit 1 set.  Adjust
	recursive calls, and calls to expand_param.
	(expand_expr): Handle EXPAND_STACK_PARM modifier.  When cse
	expected, set target to 0 rather than to subtarget.  Formatting.
