| # 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[, token flag] |
| # |
| # 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. |
| # |
| # If 'token flag' is present, this value will be assigned to tokflag field in |
| # 'struct tokendata tokendata[]' table. Token flag can be used for specifying |
| # special usage of corresponding register. E.g. opmask registers can be either |
| # enclosed by curly braces or standalone operand depending on the usage. |
| # |
