#
# List of registers and their classes; classes are defined in nasm.h
#
# The columns are:
#
# register name, assembler class, disassembler class(es), x86 register number
#
# If the register name ends in two numbers separated by a dash, then it is
# repeated as many times as indicated, and the register number is
# updated with it.
#
# General-purpose registers
