This directory contains a sample language front end for LLVM. It is a *very* simple/crude implementation of FORTH. It has many deficiencies but provides enough basics to give you an idea of what programming a new language front end for LLVM looks like. To keep things simple, Stacker has the following limitations: 1. Only a single, global stack is manipulated. 2. There is no interpretation, everything is compiled. 3. There's no type/bounds checking .. you're on your own. 4. There's no floating point support. 5. Only stdin can be read. Only stdout can be written. No other file I/O is supported. As such, this isn't a very useful language for anything other than the most trivial of programs. It is, however, a good learning tool (for both the author and the student).
