        * config/rs6000/rs6000.h: Split XCOFF specific stuff into
        xcoff.h. 
        Move AIX specific stuff into aix.h.
-       (ASM_LONG): Use DOUBLE_INT_ASM_OP if we are on a 64 bit target.
-       (ASM_OUTPUT_DOUBLE_INT): Ditto.
        (TARGET_AIX): Renamed to TARGET_XCOFF, since the AIX ABI is used
        with more than just XCOFF now.
        (SET_ASM_OP): Remove, now defined where needed.
