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). + +Reid Spencer +16 November 2003 |
