Constructors

LoaderState 

Fields

  • closure_env :: ClosureEnv

    Current global mapping from Names to their true values

  • itbl_env :: !ItblEnv

    The current global mapping from RdrNames of DataCons to info table addresses. When a new Unlinked is linked into the running image, or an existing module in the image is replaced, the itbl_env must be updated appropriately.

  • bcos_loaded :: !LinkableSet

    The currently loaded interpreted modules (home package)

  • objs_loaded :: !LinkableSet

    And the currently-loaded compiled modules (home package)

  • pkgs_loaded :: !PkgsLoaded

    The currently-loaded packages; always object code haskell libraries, system libraries, transitive dependencies

  • temp_sos :: ![(FilePath, String)]

    We need to remember the name of previous temporary DLL/.so libraries so we can link them (see #10322)

data Linkable Source #

Information we can use to dynamically link modules into the compiler

Fields

Instances

Instances details
Outputable Linkable Source # 
Instance details

Defined in GHC.Linker.Types

Methods

ppr :: Linkable -> SDoc Source #

data Unlinked Source #

Objects which have yet to be linked by the compiler

Constructors

DotO ObjFile

An object file (.o)

DotA FilePath

Static archive file (.a)

DotDLL FilePath

Dynamically linked library file (.so, .dll, .dylib)

BCOs CompiledByteCode [SptEntry]

A byte-code object, lives only in memory. Also carries some static pointer table entries which should be loaded along with the BCOs. See Note [Grand plan for static forms] in GHC.Iface.Tidy.StaticPtrTable.

Outputable SptEntry Source #

Defined in GHC.Linker.Types

Methods

ppr :: SptEntry -> SDoc Source #

isObject :: Unlinked -> Bool Source #

Is this an actual file on disk we can link in somehow?

nameOfObject :: Unlinked -> FilePath Source #

Retrieve the filename of the linkable if possible. Panic if it is a byte-code object

isInterpretable :: Unlinked -> Bool Source #

Is this a bytecode linkable with no file on disk?

byteCodeOfObject :: Unlinked -> CompiledByteCode Source #

Retrieve the compiled byte-code if possible. Panic if it is a file-based linkable
