Information we can use to dynamically link modules into the compiler

Constructors

Fields

linkableTime :: UTCTime
Time at which this linkable was built (i.e. when the bytecodes were produced, or the mod date on the files)
linkableModule :: Module
The linkable module itself
linkableUnlinked :: [Unlinked]
Those files and chunks of code we have yet to link.
INVARIANT: A valid linkable always has at least one Unlinked item. If this list is empty, the Linkable represents a fake linkable, which is generated in HscNothing mode to avoid recompiling modules.
ToDo: Do items get removed from this list when they get linked?

Instances details

Outputable Linkable #
Instance details Defined in LinkerTypes Methods ppr :: Linkable -> SDoc Source # pprPrec :: Rational -> Linkable -> SDoc Source #

Objects which have yet to be linked by the compiler

Constructors

DotO FilePath	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 [Grant plan for static forms] in StaticPtrTable.

Instances details

Outputable Unlinked #
Instance details Defined in LinkerTypes Methods ppr :: Unlinked -> SDoc Source # pprPrec :: Rational -> Unlinked -> SDoc Source #

An entry to be inserted into a module's static pointer table. See Note [Grand plan for static forms] in StaticPtrTable.
