2003-03-21  H.J. Lu  <hongjiu.lu@intel.com>

	* i386-dis.c (REX_MODE64): Remove definition.
	(REX_EXTX): Likewise.
	(REX_EXTY): Likewise.
	(REX_EXTZ): Likewise.
	(USED_REX): Use REX_OPCODE instead of 0x40.
	Replace REX_MODE64, REX_EXTX, REX_EXTY and REX_EXTZ with REX_W,
	REX_R, REX_X and REX_B respectively.
