ASSEMBLER DEVICE, PARSING METHOD, AND ASSEMBLER PROGRAM

摘要

In order to provide an assembler device capable of working with a variety of syntaxes, an assembler device for reading in an input file including a program written in assembly language and outputting object code of the program is provided with a token information table for representing tokens constituting syntax of each command or constituent patterns of operand variables for the assembler device that outputs object code of the program; an operand information table for representing meanings of the operand variables or tokens to be candidates; and a parsing unit for parsing an input string of an input file into a plurality of tokens, and searching for commands having constituent patterns of tokens matching constituent patterns of obtained tokens from the token information table while referring to the operand information table.
