I've just verified that this fix

        * expr.h (enum block_op_methods): New.
        (emit_block_move): Update prototype.
        * expr.c (block_move_libcall_safe_for_call_parm): New.
        (emit_block_move_via_loop): New.
        (emit_block_move): Use them.  New argument METHOD.
        (emit_push_insn): Always respect the given alignment.
        (expand_assignment): Update call to emit_block_move.
        (store_expr, store_field, expand_expr): Likewise.
        * builtins.c (expand_builtin_apply): Likewise.
        (expand_builtin_memcpy, expand_builtin_va_copy): Likewise.
        * function.c (expand_function_end): Likewise.
        * config/sh/sh.c (sh_initialize_trampoline): Likewise.
        * config/sparc/sparc.c (sparc_va_arg): Likewise.
        * calls.c (expand_call, emit_library_call_value_1): Likewise.
        (save_fixed_argument_area): Use emit_block_move with
        BLOCK_OP_CALL_PARM instead of move_by_pieces.
        (restore_fixed_argument_area): Likewise.
        (store_one_arg): Fix alignment parameter to emit_push_insn.

fixes PR 6241, which reports the ppc variant of this bug.  I don't
have GNATS write access.
