Analyzing Haskell call graph (was: Thread on Discourse - HIE file processing)

[Tristan Cacqueray]

Hi Sylvain,

Using the output of the renamer looks good. However it doesn't seem like
it contains the typeclass instances: when calling a typeclass method for
a given type, the AST contains the name of the method and the type, but
not the instance. Is it complicated to lookup the relevant instance
from the renamer output?

Thanks,
-Tristan
