        * pdp11.h (TARGET_SWITCHES): Fix error in previous change.
        (ASSEMBLER_DIALECT): Define.
        (CONDITIONAL_REGISTER_USAGE): Rename floating point registers if
        required for the UNIX assembler.
        (ASM_OUTPUT_INT): Remove.  The compiler will synthesise it.
        (ASM_OUTPUT_ADDR_VEC_PROLOGUE): Remove.
        (ASM_OPEN_PAREN, ASM_CLOSE_PAREN): Change to "[" and "]".
        (TRAMPOLINE_TEMPLATE): Use ASM_OUTPUT_SHORT.
        * pdp11.c (output_addr_const_pdp11): Copy of output_addr_const
        adapted to output constants in octal.
        * pdp11.c, pdp11.h, pdp11.md: Use output_addr_const_pdp11 instead
        of output_addr_const.  Output constants in octal.  Use assembler
        dialect alternatives where DEC and UNIX assemblers use different
        instruction names.
