	gcc            : ChangeLog expr.h expr.c calls.c function.c 
	                 stmt.c Makefile.in 
	gcc/doc        : tm.texi 
	gcc/config/rs6000: linux64.h rs6000.h rs6000.c 

Log message:
	* doc/tm.texi (BLOCK_REG_PADDING): Describe.
	* expr.h (struct locate_and_pad_arg_data): Add where_pad.
	(emit_group_load, emit_group_store): Adjust declarations.
	Remove most occurrences of #ifdef TREE_CODE.
	* expr.c (emit_group_load): Add "type" param, and use
	BLOCK_REG_PADDING to determine need for a shift.  Optimize non-
	aligned accesses if !SLOW_UNALIGNED_ACCESS.
	(emit_group_store): Likewise.
	(emit_push_insn, expand_assignment, store_expr, expand_expr): Adjust
	emit_group_load and emit_group_store calls.
	* calls.c (store_unaligned_arguments_into_pseudos): Tidy.  Use
	BLOCK_REG_PADDING to determine whether we need endian_correction.
	(load_register_parameters): Localize vars.  Handle shifting of
	small values to the correct end of regs.  Adjust emit_group_load
	call.
	(expand_call, emit_library_call_value_1): Adjust emit_group_load
	and emit_group_store calls.
	* function.c (assign_parms): Set mem alignment for stack slots.
	Adjust emit_group_store call.  Store values at the "wrong" end
	of regs to the stack.  Use BLOCK_REG_PADDING.
	(locate_and_pad_parm): Save where_pad.
	(expand_function_end): Adjust emit_group_load call.
	* stmt.c (expand_value_return): Adjust emit_group_load call.
	* Makefile.in (calls.o): Depend on $(OPTABS_H).
	* config/rs6000/linux64.h (TARGET_LITTLE_ENDIAN): Redefine as 0.
	(AGGREGATE_PADDING_FIXED, AGGREGATES_PAD_UPWARD_ALWAYS): Define.
	(MUST_PASS_IN_STACK): Define.
	(BLOCK_REG_PADDING): Define.
	* config/rs6000/rs6000.h (struct rs6000_args): Remove orig_nargs.
	(PAD_VARARGS_DOWN): Define in terms of FUNCTION_ARG_PADDING.
	* config/rs6000/rs6000.c (init_cumulative_args): Don't set orig_nargs.
	(function_arg_padding): !AGGREGATE_PADDING_FIXED compatibility code.
	Act on AGGREGATES_PAD_UPWARD_ALWAYS.
