oneShot :: HscEnv -> StopPhase -> [(String, Maybe Phase)] -> IO () Source #

compileFile :: HscEnv -> StopPhase -> (FilePath, Maybe Phase) -> IO (Maybe FilePath) Source #

Interfaces for the compilation manager (interpreted/batch-mode)

preprocess Source #

Arguments

:: HscEnv
-> FilePath	input filename
-> Maybe InputFileBuffer	optional buffer to use instead of reading the input file
-> Maybe Phase	starting phase
-> IO (Either DriverMessages (DynFlags, FilePath))

Just preprocess a file, put the result in a temp. file (used by the compilation manager during the summary phase).

We return the augmented DynFlags, because they contain the result of slurping in the OPTIONS pragmas

compileOne Source #

Arguments

:: HscEnv
-> ModSummary	summary for module being compiled
-> Int	module N ...
-> Int	... of M
-> Maybe ModIface	old interface, if we have one
-> Maybe Linkable	old linkable, if we have one
-> IO HomeModInfo	the complete HomeModInfo, if successful

Compile

Compile a single module, under the control of the compilation manager.

This is the interface between the compilation manager and the compiler proper (hsc), where we deal with tedious details like reading the OPTIONS pragma from the source file, converting the C or assembly that GHC produces into an object file, and compiling FFI stub files.

NB. No old interface can also mean that the source has changed.

compileOne' Source #

Arguments

:: Maybe Messager
-> HscEnv
-> ModSummary	summary for module being compiled
-> Int	module N ...
-> Int	... of M
-> Maybe ModIface	old interface, if we have one
-> Maybe Linkable	old linkable, if we have one
-> IO HomeModInfo	the complete HomeModInfo, if successful

compileForeign :: HscEnv -> ForeignSrcLang -> FilePath -> IO FilePath Source #

compileEmptyStub :: DynFlags -> HscEnv -> FilePath -> ModLocation -> ModuleName -> IO () Source #

Linking

link Source #

Arguments

:: GhcLink	interactive or batch
-> Logger	Logger
-> TmpFs
-> Hooks
-> DynFlags	dynamic flags
-> UnitEnv	unit environment
-> Bool	attempt linking in batch mode?
-> Maybe (RecompileRequired -> IO ())
-> HomePackageTable	what to link
-> IO SuccessFlag
