Hello
I have a failing test in BuildWrapper when moving from GHC 7.0.4 to
7.4.1. As far I can tell, in the TypecheckedSource I get DataCon
objects that have no location info, and hence I can't retrieve them by
location... Which is useful in a IDE (tell me what's under my mouse
cursor, tell me where else it's used).
Given the simple data declaration:
data DataT=MkData {name :: String}
In 7.0.4 I obtain a hierarchy that ends in FunBind (on a Var called
"name")/MatchGroup/Match/ConPatOut and the contained DataCon named
"MkData" has a SrcSpan associated with it, and so do the Var,
MatchGroup and Match.
In 7.4.1 I have the same hierarchy but the DataCon tells me "no
location info". The Var "name" has a location, but the MatchGroup and
Match don't either.
Is it a normal change? Do I need to change something in the way I load
the module? Is it a regression?
It sounds like a regression. Please create a ticket and we'll look into it.
Cheers,
Simon
