llvm dev - Mar 2016 - [GSOC] Forth Frontend for LLVM or LLVM Superoptimizer

Hi,

I would like to work on a new Forth frontend for LLVM or possibly for
another language. I am also interested on the LLVM superoptimizer
project, but I don't currently know how to work on the backend of a
compiler. What things should I understand before tackling such a
project?

For the first project, I think you should understand the LLVM IR and how 
to use the C++ API (e.g., the IRBuilder class) to create and manipulate 
the IR.  If you can write a simple LLVM pass, that would be a good start.

For the second project, I'm not really sure.  You should look at the 
existing work and see if it transforms code at the LLVM IR level or the 
MachineIntr level (i.e., is it a ModulePass/FunctionPass or a 
MachineFunctionPass?).  That will guide you on what background you need.

Just out of curiosity, why the interest in Forth?
