; List of valid instruction/operand combinations
;
; Copyright (C) 2001 Peter Johnson
; See the parser file for a list of possible operand values and their meanings.
; gen_instr.pl translates this list into lexer and parser code.
;
-; Instructions are listed in the order given by the "IA-32 Intel Architecture
-; Software Developer's Manual, Volume 2: Instruction Set Reference." Order
-; #245471.
+; Instructions are listed in the same order as that in GNU binutils

; Finish instructions (may require changing parser code).
; Doublecheck AMD and Cyrix instructions.
; Doublecheck the segreg mov instructions.

; Instruction Groupings (to shorten parser code).
; The $0.1, $0.2, and $0.3 will get replaced with the parameters given for
