Execute an action of type IO [a], returning ForeignHValues for each of the results.

We can pass simple expressions to EvalStmt, consisting of values and application. This allows us to wrap the statement to be executed in another function, which is used by GHCi to implement :set args and :set prog. It might be worthwhile to extend this little language in the future.

Execute an action of type IO ()

Execute an action of type IO String

Execute an action of type String -> IO String

Allocate and store the given bytes in memory, returning a pointer to the memory in the remote process.

Create a set of BCOs that may be mutually recursive.

loadDLL loads a dynamic library using the OS's native linker (i.e. dlopen() on Unix, LoadLibrary() on Windows). It takes either an absolute pathname to the file, or a relative filename (e.g. "libfoo.so" or "foo.dll"). In the latter case, loadDLL searches the standard locations for the appropriate library.

Returns:

Nothing => success Just err_msg => failure

Run a command in the interpreter's context. With -fexternal-interpreter, the command is serialized and sent to an external iserv process, and the response is deserialized (hence the Binary constraint). With -fno-external-interpreter we execute the command directly here.

A Message a is a message that returns a value of type a. These are requests sent from GHC to the server.

Grab a lock on the IServ and do something with it. Overloaded because this is used from TcM as well as IO.

Send a Message and receive the response from the iserv process

Read a value from the iserv process

Send a value to the iserv process

Creates a ForeignRef that will automatically release the RemoteRef when it is no longer referenced.

Convert a ForeignRef to the value it references directly. This only works when the interpreter is running in the same process as the compiler, so it fails when -fexternal-interpreter is on.
