Not GP, but after doing Crafting Interpreters I was kinda left with a gap in my knowledge regarding the conversion of an AST into native code. Also kinda missing was optimization passes over an AST. I somewhat understand the idea, but it would definitely be nice to have a more guided book/article for this.

Crafting Interpreters is definitely a recommended read, but it stops at Interpreters (fair enough, the book is thick enough). Crafting Compilers would need at least 4-5 extra chapters IMO.

Hmm I would have hoped for something more formal and that's focused on compiled runtimes, instead of dynamic runtimes

Still, I appreciate you replying, I'm sure you meant to be helpful!
