      Add a class HasDynFlags(getDynFlags) · 06c6d970
      Ian Lynagh authored
      We no longer have many separate, clashing getDynFlags functions
      
      I've given each GhcMonad its own HasDynFlags instance, rather than
      using UndecidableInstances to make a GhcMonad m => HasDynFlags m
      instance.

      Implement a capi calling convention; fixes #2979 · 36f8cabe
      Ian Lynagh authored
      In GHC, this provides an easy way to call a C function via a C wrapper.
      This is important when the function is really defined by CPP.
      
      Requires the new CApiFFI extension.
      
      Not documented yet, as it's still an experimental feature at this stage.

      Track #included files for recompilation checking (#4900, #3589) · 3f34e091
      Simon Marlow authored
      This was pretty straightforward: collect the filenames in the lexer,
      and add them in to the tcg_dependent_files list that the typechecker
      collects.
      
      Note that we still don't get #included files in the ghc -M output.
      Since we don't normally lex the whole file in ghc -M, this same
      mechanism can't be used directly.

      New kind-polymorphic core · 09015be8
      dreixel authored
      This big patch implements a kind-polymorphic core for GHC. The current
      implementation focuses on making sure that all kind-monomorphic programs still
      work in the new core; it is not yet guaranteed that kind-polymorphic programs
      (using the new -XPolyKinds flag) will work.
      
      For more information, see http://haskell.org/haskellwiki/GHC/Kinds

      Implement -XConstraintKind · 9729fe7c
      batterseapower authored
      Basically as documented in http://hackage.haskell.org/trac/ghc/wiki/KindFact,
      this patch adds a new kind Constraint such that:
      
        Show :: * -> Constraint
        (?x::Int) :: Constraint
        (Int ~ a) :: Constraint
      
      And you can write *any* type with kind Constraint to the left of (=>):
      even if that type is a type synonym, type variable, indexed type or so on.
      
      The following (somewhat related) changes are also made:
       1. We now box equality evidence. This is required because we want
          to give (Int ~ a) the *lifted* kind Constraint
       2. For similar reasons, implicit parameters can now only be of
          a lifted kind. (?x::Int#) => ty is now ruled out
       3. Implicit parameter constraints are now allowed in superclasses
          and instance contexts (this just falls out as OK with the new
          constraint solver)
      
      Internally the following major changes were made:
       1. There is now no PredTy in the Type data type. Instead
          GHC checks the kind of a type to figure out if it is a predicate
       2. There is now no AClass TyThing: we represent classes as TyThings
          just as a ATyCon (classes had TyCons anyway)
       3. What used to be (~) is now pretty-printed as (~#). The box
          constructor EqBox :: (a ~# b) -> (a ~ b)
       4. The type LCoercion is used internally in the constraint solver
          and type checker to represent coercions with free variables
          of type (a ~ b) rather than (a ~# b)

      Refactor SrcLoc and SrcSpan · b2bd63f9
      Ian Lynagh authored
      The "Unhelpful" cases are now in a separate type. This allows us to
      improve various things, e.g.:
      * Most of the panic's in SrcLoc are now gone
      * The Lexer now works with RealSrcSpans rather than SrcSpans, i.e. it
        knows that it has real locations and thus can assume that the line
        number etc really exists
      * Some of the more suspicious cases are no longer necessary, e.g.
        we no longer need this case in advanceSrcLoc:
            advanceSrcLoc loc _ = loc -- Better than nothing
      
      More improvements can probably be made, e.g. tick locations can
      probably use RealSrcSpans too.

      Added a VECTORISE pragma · f2aaae97
      chak@cse.unsw.edu.au. authored
      - Added a pragma {-# VECTORISE var = exp #-} that prevents
        the vectoriser from vectorising the definition of 'var'.
        Instead it uses the binding '$v_var = exp' to vectorise
        'var'.  The vectoriser checks that the Core type of 'exp'
        matches the vectorised Core type of 'var'.  (It would be
        quite complicated to perform that check in the type checker
        as the vectorisation of a type needs the state of the VM
        monad.)
      - Added parts of a related VECTORISE SCALAR pragma
      - Documented -ddump-vect
      - Added -ddump-vt-trace
      - Some clean up

      multiline commands in GHCi #4316 · 4edbeb14
      vivian authored
      This patch adds support for multiline commands in GHCi.
      
      The first line of input is lexed.  If there is an active
      layout context once the lexer reaches the end of file, the
      user is prompted for more input.
      
      Multiline input is exited by an empty line and can be escaped 
      with a user interrupt.
      
      Multiline mode is toggled with `:set +m`
