I haven't tried this recently on GHC but my first instinct would be to
use hasktags [1]:

    $ cabal install hasktags
    $ hasktags --etags ./compiler

At some point in the past I would have said that ideally Hadrian would
be able to build such a thing. However, at this point TAGS files are
slowly falling out of fashion in favor of language servers.

Another way to reach a similar end would be to rather search-and-replace
across all git-tracked files. However, somewhat surprisingly, a bit of
Googling didn't turn up any easy way of accomplishing this. The
closest I can find is [1].

Cheers,
