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
