> There are better books I would probably recommend

I'm curious what you'd recommend.

For what it's worth my goal was to compile to machine code. Anything less would have seemed insufficient. Later I got Appel's "Modern Compiler Implementation in Java" and Allen and Kennedy "Optimizing Compilers for Modern Architectures".

Cooper and Torczon "Engineering a Compiler" was recommended here recently. I haven't seen it.

I got started from the books that were available here in the early 2000s. The one I like the most is "Programming Language Pragmatics" by Michael Scott, mainly for its simplicity. Then there is "Advanced Compiler Design and Implementation" by Steven Muchnick. I have Allen-Kennedy's book too, but I think it went over my head when I went through it. So I kept it aside.

"Engineering a Compiler" is quite approachable.

But, once you know the basics, you get the best bang-for-the-buck by looking at source code of various compilers and virtual machines.

There is a whole body of non-academic work aimed at practioners for implementing compilers.

I don't think that the ghuloum 2006 paper was the initial basis for nanopass, at least the paper A Nanopass Framework for Compiler Education∗ seems to predate it in 2004 https://dl.acm.org/doi/10.1145/1016848.1016878
