The HERMIT Kernel

data AST

A handle for a specific version of the ModGuts.

data Kernel

A Kernel is a repository for complete Core syntax trees (ModGuts). For now, operations on a Kernel are sequential, but later it will be possible to have two applyKs running in parallel.

data KernelEnv

Constructors

KernelEnv

Fields

kEnvChan :: DebugMessage -> HermitM ()

hermitKernel :: (Kernel -> AST -> IO ()) -> ModGuts -> CoreM ModGuts

Start a HERMIT client by providing an IO function that takes the initial Kernel and inital AST handle. The Modguts to CoreM Modguts' function required by GHC Plugins is returned. The callback is only ever called once.

resumeK :: Kernel -> AST -> IO ()

Halt the Kernel and return control to GHC, which compiles the specified AST.

abortK :: Kernel -> IO ()

Halt the Kernel and abort GHC without compiling.

applyK :: Kernel -> AST -> RewriteH ModGuts -> KernelEnv -> IO (KureM AST)

Apply a Rewrite to the specified AST and return a handle to the resulting AST.

queryK :: Kernel -> forall a. AST -> TransformH ModGuts a -> KernelEnv -> IO (KureM a)

Apply a TransformH to the AST and return the resulting value.

deleteK :: Kernel -> AST -> IO ()

Delete the internal record of the specified AST.

listK :: Kernel -> IO [AST]

List all the ASTs tracked by the Kernel.
