I can give an overview here – I’m also intending to do a proper write-up of the system at some point into a docs file in the Zig repo, although that’ll probably assume a bit more technical background (since it’ll be targeted towards existing compiler devs). First, we need to understand the compiler pipeline. After parsing (which is boring), there are three important stages: AstGen Sema CodeGen AstGen consumes a parsed AST and generates an instruction-based intermediate represe…
