Table Driven Assembler

The Table Driven Assembler (TDASM) is a free portable cross assembler for any kind of assembly language. It should be possible to use it as a compiler to any target microprocessor using a table that defines the compilation process.

I am developing this program under Linux RedHat 6.0 under KDevelop 1.1 environment as the school project.

Main features

• possible compilation to any target procesor using a table description that will include:
  • definition of target procesor's properties
    • endianess
    • size of basic number types
    • registers and their sizes
    • instruction format
  • definition of syntax of assembly language
    • syntax of numbers with different bases
    • syntax of comments
    • instruction separators
    • strings definition and generation
  • means to control the code generation
    • variable size of any part of instruction support
    • commands to set any part of instruction to general expression
    • modification of any bits of instruction part
    • directives for branch code generation on condition
    • source code's symbol table administration directives
  • definition of general operands using regular expressions with automatic code generation
  • instruction table definition using general operands and regular expressions
  • support for symols in source code
  • support for general expressions in source code
  • instruction and operand prefixes support
  • possibility to define more instruction sets depending on processor mode
  • segmentation support
• full object oriented design
• implemetation using Standard Template Library of ISO C++
• portable to many platforms on source level
• distributed under the GNU Public License (GPL) version 2

Notes

This project is under developement at school, so many features are not implemented yet. You can download and try developement version. There are two examples of tables that define compilation process to procesors Intel x86 and Zilog Z80. Tables are not complete, they serve only as an ilustration what the implemented prototype can do.

Compilation

• decompress the source code: tar zxvf tdasm-?.?.?.tar.gz
• type ./configure to create makefiles for your system
• compile using make
• optionaly install into /usr/local/bin by executing make install

Usage

tdasm <table_file> <source_file>

The result of execution is an output binary file source_file.out and a file with listing source_file.lst.

Download

You might need cwsdpmi.exe for execution of dos binary.
