data HscTarget

Source

The target code type of the compilation (if any).

Whenever you change the target, also make sure to set ghcLink to something sensible.

HscNothing can be used to avoid generating any output, however, note that:

This will not run the desugaring step, thus no warnings generated in this step will be output. In particular, this includes warnings related to pattern matching. You can run the desugarer manually using GHC.desugarModule.
If a program uses Template Haskell the typechecker may try to run code from an imported module. This will fail if no code has been generated for this module. You can use GHC.needsTemplateHaskell to detect whether this might be the case and choose to either switch to a different target or avoid typechecking such modules. (The latter may preferable for security reasons.)

Constructors

HscC	Generate C code.
HscAsm	Generate assembly using the native code generator.
HscJava	Generate Java bytecode.
HscInterpreted	Generate bytecode. (Requires `LinkInMemory`)
HscNothing	Don't generate any code. See notes above.

Instances

Eq HscTarget

Show HscTarget

isObjectTarget :: HscTarget -> Bool

Source

Will this target result in an object file on the disk?

defaultObjectTarget :: HscTarget

Source

The HscTarget value corresponding to the default way to create object files on the current platform.

data GhcMode

Source

The GhcMode tells us whether we're doing multi-module compilation (controlled via the GHC API) or one-shot (single-module) compilation. This makes a difference primarily to the Finder: in one-shot mode we look for interface files for imported modules, but in multi-module mode we look for source files in order to check whether they need to be recompiled.

Constructors

CompManager	`--make`, GHCi, etc.
OneShot	ghc -c Foo.hs
MkDepend	`ghc -M`, see Finder for why we need this

Instances

Eq GhcMode

Outputable GhcMode

isOneShot :: GhcMode -> Bool

Source

data GhcLink

Source

What to do in the link step, if there is one.

Constructors

NoLink	Don't link at all
LinkBinary	Link object code into a binary
LinkInMemory	Use the in-memory dynamic linker (works for both bytecode and object code).
LinkDynLib	Link objects into a dynamic lib (DLL on Windows, DSO on ELF platforms)

Instances

Eq PackageFlag

data Option

Source

When invoking external tools as part of the compilation pipeline, we pass these a sequence of options on the command-line. Rather than just using a list of Strings, we use a type that allows us to distinguish between filepaths and 'other stuff'. The reason for this is that this type gives us a handle on transforming filenames, and filenames only, to whatever format they're expected to be on a particular platform.

Constructors

FileOption String String
Option String

Manipulating DynFlags

defaultDynFlags :: DynFlags

Source

The normal DynFlags. Note that they is not suitable for use in this form and must be fully initialized by GHC.newSession first.

initDynFlags :: DynFlags -> IO DynFlags

Source

Used by GHC.newSession to partially initialize a new DynFlags value

dopt :: DynFlag -> DynFlags -> Bool

Source

Test whether a DynFlag is set

dopt_set :: DynFlags -> DynFlag -> DynFlags

Source

Set a DynFlag

dopt_unset :: DynFlags -> DynFlag -> DynFlags

Source

Unset a DynFlag

getOpts

Source

:: DynFlags	`DynFlags` to retrieve the options from
-> DynFlags -> [a]	Relevant record accessor: one of the `opt_*` accessors
-> [a]	Correctly ordered extracted options
Retrieve the options corresponding to a particular `opt_*` field in the correct order

getVerbFlag :: DynFlags -> String

Source

Gets the verbosity flag for the current verbosity level. This is fed to other tools, so GHC-specific verbosity flags like -ddump-most are not included

updOptLevel :: Int -> DynFlags -> DynFlags

Source

Sets the DynFlags to be appropriate to the optimisation level

setTmpDir :: FilePath -> DynFlags -> DynFlags

Source

setPackageName :: String -> DynFlags -> DynFlags

Source

doingTickyProfiling :: DynFlags -> Bool

Source

Parsing DynFlags

parseDynamicFlags

Source

:: Monad m
=> DynFlags
-> [Located String]
-> m (DynFlags, [Located String], [Located String])	Updated `DynFlags`, left-over arguments, and list of warnings.
Parse dynamic flags from a list of command line arguments. Returns the the parsed `DynFlags`, the left-over arguments, and a list of warnings. Throws a `UsageError` if errors occurred during parsing (such as unknown flags or missing arguments).

parseDynamicNoPackageFlags

Source

:: Monad m
=> DynFlags
-> [Located String]
-> m (DynFlags, [Located String], [Located String])	Updated `DynFlags`, left-over arguments, and list of warnings.
Like `parseDynamicFlags` but does not allow the package flags (-package, -hide-package, -ignore-package, -hide-all-packages, -package-conf).
