Arguments
| :: HscEnv | |
| -> FilePath | input filename |
| -> Maybe InputFileBuffer | optional buffer to use instead of reading the input file |
| -> Maybe Phase | starting phase |
| -> IO (Either ErrorMessages (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
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 |
| -> SourceModified | |
| -> 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.

phaseOutputFilename :: Phase -> CompPipeline FilePath Source #
Computes the next output filename after we run next_phase.
Like getOutputFilename, but it operates in the CompPipeline monad
(which specifies all of the ambient information.)
getOutputFilename :: Phase -> PipelineOutput -> String -> DynFlags -> Phase -> Maybe ModLocation -> IO FilePath Source #
Computes the next output filename for something in the compilation pipeline. This is controlled by several variables:
Phase: the last phase to be run (e.g.stopPhase). This is used to tell if we're in the last phase or not, because in that case flags like-omay be important.PipelineOutput: is this intended to be aTemporaryorPersistentbuild output? Temporary files just go in a fresh temporary name.String: what was the basename of the original input file?DynFlags: the obvious thingPhase: the phase we want to determine the output filename of.Maybe ModLocation: theModLocationof the module we're compiling; this can be used to override the default output of an object file. (TODO: do we actually need this?)
hscPostBackendPhase :: HscSource -> HscTarget -> Phase Source #
What phase to run after one of the backend code generators has run
getLocation :: HscSource -> ModuleName -> CompPipeline ModLocation Source #
setModLocation :: ModLocation -> CompPipeline () Source #
setDynFlags :: DynFlags -> CompPipeline () Source #
Arguments
| :: PhasePlus | Run this phase |
| -> FilePath | name of the input file |
| -> DynFlags | for convenience, we pass the current dflags in |
| -> CompPipeline (PhasePlus, FilePath) |
Each phase in the pipeline returns the next phase to execute, and the name of the file in which the output was placed.
We must do things dynamically this way, because we often don't know what the rest of the phases will be until part-way through the compilation: for example, an {-# OPTIONS -fasm #-} at the beginning of a source file can change the latter stages of the pipeline from taking the LLVM route to using the native code generator.
