| 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). |
