The majority of people those references will learn toy-compilers, that are surely important but a completely different league than production-grade compilers, e.g: LLVM.
Talking specifically about LLVM, does someone have their go-to references to start and have a sense of the infrastructure, or even some specific reading about a part of the (huge) infrastructure?

Not by any means a tutorial but Rust has a guide for understanding their LLVM compiler frontend. It has some useful insights into what actually makes up a real "production grade" compiler outside the stuff in the LLVM tutorial.
Awesome jobs by Rust to keep something like that (hopefully updated too), since the lack of updated information usually is the bigger barrier of entry for contributing/working on stuff like that. I struggle to find something similar and in-depth for clang, but I guess the bigger complexity makes it more difficult.
This makes the learning process self-serve.
