Implementing continuation passing style

I have recently been struggling to implement transformation of Common Lisp source code to continuation passing style (CPS) in my owlisp compiler. I’m not yet done with that, but after hours of racking my brains, it’s finally on a good way as it seems 😉 . The

Switching target language from LLVM-IR to C

I think I need to pivot! What I intended originally was to write a compiler that translates from Common Lisp to LLVM IR. Well, I recently stumbled over this article, that convinced me to make my compiler target the C programming language instead of LLVM IR. There

Working on a runtime & cancelling needless components

After reading some more (mostly on the net, but also in books, especially Engineering a Compiler & Modern Compiler Implementation in ML) and wrapping my mind around the whole subject of the internal structure of compilers more and more in detail (especially regarding SSA), I started realizing

owlisp does now compile to SECD virtual machine code

owlisp now has an internal SECD virtual machine and compiles expressions to byte-code that this VM understands (see README). I have implemented a VM because I think it might be a nice abstraction layer between the Lisp code and the resulting LLVM-IR and/or Parrot VM IR. It

owlisp interpreter, compiler wannabe

I have recently been doing a bit of work on owlisp to implement an interpreter. This is meant as a first step towards building the compiler (LLVM frontend) that I am aiming at. But before going into details of my recent work: Using the interpreter The interpreter
