 /* ---------------------------------------------- Opcode Table Descriptions */
 /* the table type describes how to handle byte/size increments before
  * and after lookup. Some tables re-use the current byte, others
  * consume a byte only if the ModR/M encodes no operands, etc */

 	tbl_opcode = 0,	/* standard opcode table: no surprises */
 	tbl_prefix,	/* Prefix Override, e.g. 66/F2/F3 */
 	tbl_suffix,	/* 3D Now style */
 	tbl_extension,	/* ModR/M extension: 00-FF -> 00-07 */
 	tbl_ext_ext,	/* extension of modr/m using R/M field */
 	tbl_fpu,	/* fpu table: 00-BF -> 00-0F */
 	tbl_fpu_ext	/* fpu extension : C0-FF -> 00-1F */
  };
 /* How it works:
  * Bytes are 'consumed' if the next table lookup requires that the byte
  * pointer be advanced in the instruction stream. 'Does not consume' means
  * that, when the lookup function recurses, the same byte it re-used in the
  * new table. It also means that size is not decremented, for example when
  * a ModR/M byte is used. Note that tbl_extension (ModR/M) instructions that
  * do not increase the size of an insn with their operands have a forced
 size increase in the lookup algo. Weird, yes, confusing, yes, welcome
  * to the Intel ISA. Another note: tbl_prefix is used as an override, so an
  * empty insn in a prefix table causes the instruction in the original table
  * to be used, rather than an invalid insn being generated.
  * 	tbl_opcode uses current byte and consumes it
  * 	tbl_prefix uses current byte but does not consume it
  * 	tbl_suffix uses and consumes last byte in insn
  * 	tbl_extension uses current byte but does not consume it
  * 	tbl_ext_ext uses current byte but does not consume it
  * 	tbl_fpu uses current byte and consumes it
  * 	tbl_fpu_ext uses current byte but does not consume it
