* h8300/h8300.c (print_operand): Handle new 'R' case for accessing
        the 8-bit area.  Make code for 'Y' fall into code for 'R' when
        operand is not a register.  Update some comments.
        (h8300_tiny_data_p): New function.
        (h8300_valid_machine_decl_attribute): Handle "tiny_data" attribute.
        * h8300/h8300.h (OK_FOR_U): Handle memory references into the
        8-bit area.
        (ENCODE_SECTION_INFO): Mark SYMBOL_REFs which refer to the 8-bit
        area.
        * h8300/h8300.md (many patterns): Use 'R' rather than 'X' for
        operands that may be memory accesses into the 8-bit area.
        (btst pattern): New pattern to set the cc0 (zbit) based on
        data in the 8-bit area.

        * h8300/h8300.md (one_cmplsi2): Fix length computation for h8300h.
