  Compiler of a small Scala subset

  You might find [CS 6120: Advanced Compilers: The Self-Guided Online Course][1] interesting. I'm slowly working through it, but basically its focus is intermediate representations, optimizations, etc. A link to the course was on the first page of HN some time ago.

  Also -- and you knew it was coming -- I've written a [toy-compiler of a Scala subset][2] myself :)

  I'm new to F# and writing compilers, so I'm sure the code is full of rookie mistakes. Still, it works and does generate assembly and executables for Linux and Windows.

  12 284 8.4 Slash

  A homebrew 16-bit CPU with a homebrew Unix-like-ish operating system.

  Thanks, this is serendipitous timing. I definitely plan to watch the YouTube playlist.

  I'm designing a simple CPU at the moment[1] and one of the things that keeps me awake at night is thinking about how to make a compiler for it.

  It only supports 64K words of RAM (and I'm not planning to implement bank switching), and I definitely want the compiler to be self-hosting on my CPU, so retargeting LLVM or similar won't be applicable.

  I've looked at Small-C[2], Cowgol[3], and PL/0[4] which all target similar goals.

• llvm-project

  348 25,451 10.0 C++

  The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.

  

  I have to keep up with Ruby changes.

  But even for example the parser in clang doesn't seem to be touched very often.

  https://github.com/llvm/llvm-project/commits/main/clang/lib/...

  Take a look at the commits there and see how much each changes the parser vs the rest of the compiler.

  Also, at the bottom of page 2 for parser changes you're already all the way back in 2017!

  I'm looking at this one for a CPU design I've been working on. :)
