Hello!

This is the current Lemmy equivalent of https://www.reddit.com/r/ProgrammingLanguages/.

The content and rules are the same here as they are over there. Taken directly from the /r/ProgrammingLanguages overview:

This community is dedicated to the theory, design and implementation of programming languages.

Be nice to each other. Flame wars and rants are not welcomed. Please also put some effort into your post.

This isn't the right place to ask questions such as "What language should I use for X", "what language should I learn", and "what's your favorite language". Such questions should be posted in /c/learn_programming or /c/programming.

This is the right place for posts like the following:

"Check out this new language I've been working on!"
"Here's a blog post on how I implemented static type checking into this compiler"
"I want to write a compiler, where do I start?"
"How does the Java compiler work? How does it handle forward declarations/imports/targeting multiple platforms/?"
"How should I test my compiler? How are other compilers and interpreters like gcc, Java, and python tested?"
"What are the pros/cons of ?"
"Compare and contrast vs. "
"Confused about the semantics of this language"
"Proceedings from PLDI / OOPSLA / ICFP / "

See /r/ProgrammingLanguages for specific examples

Compiling To Logic Gates (lemm.ee)

TLDR; do you know of any general purpose languages that can also compile a function to some representation of AND/OR gates (or NAND gates, or whatever)?

Edit: actually any algebra/formal-logical system is also fine (not just boolean algebra).

Yes, a A LOT of additional info is needed, like defining how input/output is defined, and I am interested in how those would be specified. I'm not interested in printing an actual circuit, just the boolean-logic level. And I'm mostly asking because I feel like most compilers can't generate a clean/mathematical representation from their AST. There's AST to IR, there's hard-coded optimizations on the IR, and then there's hard-coded mappings from the IR to assembly, but at no point (AFAIK) is the code turned into a algebraic/logical system where something like De Morgan's Law can be applied. And that seems really sad to me.

So you could say my real question is: what compilers have a strong logical/algebraic internal representation of their own AST?

Maybe something like Haskell or Prolog do this. The Wolfram Language almost certainly does but it's closed source.

You will need a hardware description language (HDL). Verilog and VHDL are two very established ones but they are tricky. A newcomer is Bluespec, which is now open source so if you wanna go down that rabbit hole, I'd recommend this one.

Another newcomer is Amaranth HDL which might be more approachable and transpiles to VHDL
