Learning debugger internals is suprisingly frustrating. I think it was the the GDB source code that didn't explain what anything was in its source files about interacting with registers, and just had a comment at the top that said something like "this header file is for GDB internals, you're probably looking for the man page". Then I found a post on Stackoverflow looking for the exact same info I was, but it was closed for "being too narrow and likely no use to anyone else".
