I've gotten interested in how the linker works so I've been going over this book for a while (https://www.amazon.com/Linkers-Kaufmann-Software-Engineering-Programming/dp/1558604960) and I think it 's an amazing read.

You'd think it'd be out of date but it's very informative since embedded is stuck in the past anyways, and linkers haven't changed too much since then. It even has a section on gnu linker scripts!
