jas

About

The Janus Assembler (jas) generates machine code for the vesta virtual machine.

How does it?

jas achieves code generation in three steps (as of now):

1. Lexical Analysis - syntax checks, load information about instructions and labels.
2. Semantic Analysis - instruction/operand type checking, size agreement, etc.
3. Name Resolution and Linking* - resolve undefined labels, etc.

Development files

If you want to check out jas for yourself, you'll need the following installed:

• make
• gcc

Once you're sure that you do, clone the repo:

$ git clone https://github.com/janus-cpu/janus-jas.git

and make the jas executable. Of course, you'd also need to have vesta as well.

Some Makefile targets

• make - compile the assembler
• make clean - removes any generated files
• make new - runs make clean then make again

* Note: not implemented yet.
