Bug in linking to functions in a different module

[ghc-mirror]

Original reporter: NeilMitchell

Given:

-- M1.hs --
module M1 where
-- | See 'M2.bar'.
foo :: Int
foo = 0

-- M2.hs --
module M2 where
-- | Comment
bar :: Int
bar = 0

The link in M1 points at #t:bar rather than #v:bar. That is wrong. For 100's of examples of this bug in action see http://hackage.haskell.org/packages/archive/shake/0.10.6/doc/html/Development-Shake.html.

The bug is due to a change in GHC's dataTcOccs function. If we do what the old version of dataTcOccs did we should be fine. See GHC commit 5bfd8933.

Fixed, should make it to HEAD whenever the large parser merge happens. Could cherry pick it if we're in an extreme hurry but I don't think that's necessary.

I'll close the ticket once it makes it into HEAD.

Fixed in HEAD.
