 	* 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.

 	(CONST_OK_FOR_LETTER_P): Change N to require that value is
 	positive, too.
 	(ASM_OPEN_PAREN, ASM_CLOSE_PAREN): New macro definition.

-	* config/rs6000/rs6000.md: Fix emitting of constants.
-	Fix patterns that were AIX ABI specific, but depended on
-	!TARGET_ELF (instead of DEFAULT_ABI == ABI_AIX).
