   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),
   8 # NASM register number, x86 register number
   9 #
  10 # If the register name ends in +, then it is repeated 8 times
  11 # with the following changes:
  12 # - a numerical tail to register number is incremented
  13 # - the NASM and x86 register numbers are incremented
  14 #
  15 # For 16-register register sets, two + lines are required.
