# List of registers and their classes; classes are defined in nasm.h
#
# The columns are:
#
# register name, assembler class, disassembler class(es),
# NASM register number, x86 register number
#
# If the register name ends in +, then it is repeated 8 times
# with the following changes:
# - a numerical tail to register number is incremented
# - the NASM and x86 register numbers are incremented
#
# For 16-register register sets, two + lines are required.
#
