GHC.Runtime.Interpreter.Types.SymbolCache
Description
The SymbolCache is used to cache lookups for specific symbols when using the interpreter.
Synopsis

- interpStaticInfoCache :: MVar (SymbolCache "static_info")
- interpBytesCache :: MVar (SymbolCache "bytes")
- interpFaststringCache :: MVar (UniqFM FastString (Ptr ()))
- mkInterpSymbolCache :: IO InterpSymbolCache
- lookupInterpSymbolCache :: InterpSymbol s -> InterpSymbolCache -> IO (Maybe (Ptr ()))
- updateInterpSymbolCache :: InterpSymbol s -> InterpSymbolCache -> Ptr () -> IO ()
