+
+ * 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.
