      Add test for #9407. The test is only run on Windows 64bit, as this is
      where the problem occurred.

      Rework derivation of type representations for wired-in things · 84b0ebed
      Ben Gamari authored
      Previously types defined by `GHC.Types` and `GHC.Prim` had their
      `Typeable` representations manually defined in `GHC.Typeable.Internals`.
      This was terrible, resulting in a great deal of boilerplate and a number
      of bugs due to missing or inconsistent representations (see #11120).
      Here we take a different tack, initially proposed by Richard Eisenberg:
      We wire-in the `Module`, `TrName`, and `TyCon` types, allowing them to
      be used in `GHC.Types`. We then allow the usual type representation
      generation logic to handle this module.
      `GHC.Prim`, on the other hand, is a bit tricky as it has no object code
      of its own.  To handle this we instead place the type representations
      for the types defined here in `GHC.Types`.
      On the whole this eliminates several special-cases as well as a fair
      amount of boilerplate from hand-written representations. Moreover, we
      get full coverage of primitive types for free.

      Use (&&) instead of `if` in Ix derivation · 5cce0954
      Ben Gamari authored
      We were previously using `if` in the derivation of `Ix` instances. This
      interacts badly with RebindableSyntax as the typechecker doesn't infer
      the type of the argument we give to `tagToEnum#`.
      Previously we produced, `if (ch >= ah) then (ch <= bh) else False`.
      We now produce `(ch >= ah) && (ch <= bh)`
      Fixes #11396.

      Fix combineIdenticalAlts · 514bac26
      Simon Peyton Jones authored
      This long-standing bug in CoreUtils.combineIdenticalAlts
      was shown up by Trac #11172. The effect was that it returned
      a correct set of alternatives, but a bogus set of "impossible
      default constructors".  That meant that we subsequently
      removed all the alternatives from a case, and hence ended
      up with a bogusly empty case that should not have been empty.
      See Note [Care with impossible-constructors when
      combining alternatives] in CoreUtils.

      Hide derived OccNames from user · d2ea7f94
      Ben Gamari authored
      This hides derived OccNames from the Names returned from
      runDeclsWithLocation and clarifies the documentation. This is done to
      ensure that these names (originating from, e.g., derived Generic
      instances and type representation bindings) don't show up in ghci output
      when run with `:set +t`. This fixes #11051.

      Switch from -this-package-key to -this-unit-id. · 240ddd7c
      Edward Z. Yang authored
      A small cosmetic change, but we have to do a bit of work to
      actually support it:
          - Cabal submodule update, so that Cabal passes us
            -this-unit-id when we ask for it.  This includes
            a Cabal renaming to be consistent with Unit ID, which
            makes ghc-pkg a bit more scrutable.
          - Build system is updated to use -this-unit-id rather than
            -this-package-key, to avoid deprecation warnings.  Needs
            a version test so I resurrected the old test we had
            (sorry rwbarton!)
          - I've *undeprecated* -package-name, so that we are in the same
            state as GHC 7.10, since the "correct" flag will have only
            entered circulation in GHC 8.0.
          - I removed -package-key.  Since we didn't deprecate -package-id
            I think this should not cause any problems for users; they
            can just change their code to use -package-id.
          - The package database is indexed by UNIT IDs, not component IDs.
            I updated the naming here.
          - I dropped the signatures field from ExposedModule; nothing
            was using it, and instantiatedWith from the package database
          - ghc-pkg was updated to use unit ID nomenclature, I removed
            the -package-key flags but I decided not to add any new flags
            for now.

      Replace calls to `ptext . sLit` with `text` · b8abd852
      Jan Stolarek authored
      In the past the canonical way for constructing an SDoc string literal was the
      composition `ptext . sLit`.  But for some time now we have function `text` that
      does the same.  Plus it has some rules that optimize its runtime behaviour.
      This patch takes all uses of `ptext . sLit` in the compiler and replaces them
      with calls to `text`.  The main benefits of this patch are clener (shorter) code
      and less dependencies between module, because many modules now do not need to
      import `FastString`.  I don't expect any performance benefits - we mostly use
      SDocs to report errors and it seems there is little to be gained here.
