GHC.Types.IPE

A map storing all the different uses of a specific data constructor and the approximate source position that usage arose from. The Int is an incrementing identifier which distinguishes each usage of a constructor in a module. It is paired with the source position the constructor was used at, if possible and a string which names the source location. This is the same information as is the payload for the GHC.Core.SourceNote constructor.

A map from a Name to the best approximate source position that name arose from.

Position and information about an info table. For return frames these are the contents of a CoreSyn.SourceNote.
