ghc-6.12.2: The GHC APISource codeContentsIndex
HscMain
Description

Main driver for the compiling plain Haskell source code.

This module implements compilation of a Haskell-only source file. It is not concerned with preprocessing of source files; this is handled in DriverPipeline.

hscParse :: GhcMonad m => ModSummary -> m (Located (HsModule RdrName))Source
parse a file, returning the abstract syntax
hscTypecheck :: GhcMonad m => ModSummary -> Located (HsModule RdrName) -> m TcGblEnvSource
Rename and typecheck a module
hscTypecheckRename :: GhcMonad m => ModSummary -> Located (HsModule RdrName) -> m (TcGblEnv, RenamedStuff)Source
Rename and typecheck a module, additionally returning the renamed syntax
hscDesugar :: GhcMonad m => ModSummary -> TcGblEnv -> m ModGutsSource
Convert a typechecked module to Core
makeSimpleIface :: GhcMonad m => Maybe ModIface -> TcGblEnv -> ModDetails -> m (ModIface, Bool)Source
Make a ModIface from the results of typechecking. Used when not optimising, and the interface doesn't need to contain any unfoldings or other cross-module optimisation info. ToDo: the old interface is only needed to get the version numbers, we should use fingerprint versions instead.
makeSimpleDetails :: GhcMonad m => TcGblEnv -> m ModDetailsSource
Make a ModDetails from the results of typechecking. Used when typechecking only, as opposed to full compilation.
