Fields

  • hsc_env :: HscEnv

    only the DynFlags change in the HscEnv. The DynFlags change at various points, for example when we read the OPTIONS_GHC pragmas in the Cpp phase.

  • maybe_loc :: Maybe ModLocation

    the ModLocation. This is discovered during compilation, in the Hsc phase where we read the module header.

  • foreign_os :: [FilePath]

    additional object files resulting from compiling foreign code. They come from two sources: foreign stubs, and add{C,Cxx,Objc,Objcxx}File from template haskell

data PipelineOutput Source #

Constructors

Temporary TempFileLifetime

Output should be to a temporary file: we're going to run more compilation steps on this output later.

Persistent

We want a persistent file, i.e. a file in the current directory derived from the input filename, but with the appropriate extension. eg. in "ghc -c Foo.hs" the output goes into ./Foo.o.

SpecificFile

The output must go into the specific outputFile in DynFlags. We don't store the filename in the constructor as it changes when doing -dynamic-too.
