# 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.
