   3 # List of registers and their classes; classes are defined in nasm.h
   4 #
   5 # The columns are:
   6 #
   7 # register name, assembler class, disassembler class(es), x86 register number
   8 #
   9 # If the register name ends in two numbers separated by a dash, then it is
  10 # repeated as many times as indicated, and the register number is
  11 # updated with it.
