Building GHC API Documentation?

Hello, I am trying to create my first patch, for #9294, where I want to export some extra things from Parser along with a bit of documentation. However, I cannot figure out how to regenerate the documentation for the GHC API (not for the libraries). I tried running `make html stage=0 FAST=YES` in `./compiler`, and got the following helpful message: make[2]: *** No rule to make target `html_compiler'. Stop. make[1]: *** [html_compiler] Error 2 make: *** [html] Error 2 So I'm a bit stumped. How do I regenerate Haddock documentation for the GHC API? Thanks! Andrew
