35 # List of registers and their classes; classes are defined in nasm.h
37 # The columns are:
39 # register name, assembler class, disassembler class(es), x86 register number[, token flag]
41 # If the register name ends in two numbers separated by a dash, then it is
42 # repeated as many times as indicated, and the register number is
43 # updated with it.
45 # If 'token flag' is present, this value will be assigned to tokflag field in
46 # 'struct tokendata tokendata[]' table. Token flag can be used for specifying
47 # special usage of corresponding register. E.g. opmask registers can be either
48 # enclosed by curly braces or standalone operand depending on the usage.
