GHC's *.hi files are "interface files", a product of GHC's separate
compilation. foo.hi contains the information needed to compile a
different module which depends on foo.
So a binary library package needs to contain both the object code, and
the matching interface description, which is the *.hi file. By the way,
both are very sensitive to the version of GHC that compiled them.
There's no attempt or claim at binary compatibility between GHC versions.
The GHC user manual is a great resource:
