Documentation

class LinkingLayer l where

After a CompileLayer has compiled the modules to object code, it passes the resulting object files to a LinkingLayer.

Minimal complete definition

getLinkingLayer, getCleanups

Methods

getLinkingLayer :: l -> Ptr LinkingLayer

getCleanups :: l -> IORef [IO ()]

Instances

LinkingLayer ObjectLinkingLayer

Defined in LLVM.Internal.OrcJIT.LinkingLayer

Methods

getLinkingLayer :: ObjectLinkingLayer -> Ptr LinkingLayer

getCleanups :: ObjectLinkingLayer -> IORef [IO ()]

disposeLinkingLayer :: LinkingLayer l => l -> IO ()

Dispose of a LinkingLayer.

addObjectFile :: LinkingLayer l => l -> ObjectFile -> SymbolResolver -> IO ObjectHandle

Add an object file to the LinkingLayer. The SymbolResolver is used to resolve external symbols in the module.

data ObjectLinkingLayer

Bare bones implementation of a LinkingLayer.

Constructors

Fields

• linkingLayer :: !(Ptr ObjectLinkingLayer)
• cleanupActions :: !(IORef [IO ()])

Instances

LinkingLayer ObjectLinkingLayer

Defined in LLVM.Internal.OrcJIT.LinkingLayer

Methods

getLinkingLayer :: ObjectLinkingLayer -> Ptr LinkingLayer

getCleanups :: ObjectLinkingLayer -> IORef [IO ()]

newObjectLinkingLayer :: IO ObjectLinkingLayer

Create a new ObjectLinkingLayer. This should be disposed using disposeLinkingLayer when it is no longer needed.

withObjectLinkingLayer :: (ObjectLinkingLayer -> IO a) -> IO a

bracket-style wrapper around newObjectLinkingLayer and disposeLinkingLayer.

findSymbol :: LinkingLayer l => l -> ShortByteString -> Bool -> IO (Either JITSymbolError JITSymbol)

findSymbol layer symbol exportedSymbolsOnly searches for symbol in all modules added to layer. If exportedSymbolsOnly is True only exported symbols are searched.

findSymbolIn :: LinkingLayer l => l -> ObjectHandle -> ShortByteString -> Bool -> IO (Either JITSymbolError JITSymbol)

findSymbolIn layer handle symbol exportedSymbolsOnly searches for symbol in the context of the module represented by handle. If exportedSymbolsOnly is True only exported symbols are searched.
