      This comparison is only necessary when the types being compared contain
      casts. Otherwise the structural equality of the types implies that their
      kinds are equal.

      Add more type class instances for GHC.Generics · 673efccb
      Ryan Scott authored
      GHC.Generics provides several representation data types that have
      obvious instances of various type classes in base, along with various
      other types of meta-data (such as associativity and fixity).
      Specifically, instances have been added for the following type classes
      (where possible):
          - Applicative
          - Data
          - Functor
          - Monad
          - MonadFix
          - MonadPlus
          - MonadZip
          - Foldable
          - Traversable
          - Enum
          - Bounded
          - Ix
          - Generic1

      The PowerPC native code generator does not support DWARF debug
      information. This is tracked in ticket #11261. Mark the respective
      tests broken on powerpc64.

      Overload the static form to reduce verbosity. · c1efdcc4
      Facundo Domínguez authored
      Static pointers are rarely used naked: most often they are defined at
      the base of a Closure, as defined in e.g. the distributed-closure and
      distributed-static packages. So a typical usage pattern is:
          distributeMap (closure (static (\x -> x * 2)))
      which is more verbose than it needs to be. Ideally we'd just have to
          distributeMap (static (\x -> x * 2))
      and let the static pointer be lifted to a Closure implicitly. i.e.
      what we want is to overload static literals, just like we already
      overload list literals and string literals.
      This is achieved by introducing the IsStatic type class and changing
      the typing rule for static forms slightly:
          static (e :: t) :: IsStatic p => p t

      Address #11471 by putting RuntimeRep in kinds. · d8c64e86
      eir@cis.upenn.edu authored
      See Note [TYPE] in TysPrim. There are still some outstanding
      pieces in #11471 though, so this doesn't actually nail the bug.
      This commit also contains a few performance improvements:
      * Short-cut equality checking of nullary type syns
      * Compare types before kinds in eqType
      * INLINE coreViewOneStarKind
      * Store tycon binders separately from kinds.
      This resulted in a ~10% performance improvement in compiling
      the Cabal package. No change in functionality other than
      performance. (This affects the interface file format, though.)
      This commit updates the haddock submodule.

      The issue has been fixed by other compiler update. This patch
      adds only tests, so that derived instance of Read/Show for infix
      Unicode value constructors has correct parse, satisfying Haskell

      Fix a double-free bug in -fexternal-interpreter · 23404857
      Simon Marlow authored
      Originally I planned to make this reference manually managed, but it
      looks like at some point I gave it a finalizer on the GHC side, but
      forgot to remove the manual free here.  The result is that ghc-iserv
      could crash in getStablePtr sometimes when using TH.
