These changes modify the makefiles so that the output of flex and bison are placed in the SRC directory, not the OBJ directory. It is intended that they be checked in as any other LLVM source so that platforms without convenient access to flex/bison can be compiled. From now on, if you change a .y or .l file you *must* also commit the generated .cpp and .h files. llvm-svn: 23115 |

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).
