datadata StgPipelineOpts

Constructors

StgPipelineOpts
- stgPipeline_phases :: ![StgToDo]
  Spec of what stg-to-stg passes to do
- stgPipeline_lint :: !Maybe DiagOpts
  Should we lint the STG at various stages of the pipeline?
- stgPipeline_pprOpts :: !StgPprOpts
- stgPlatform :: !Platform
- stgPipeline_forBytecode :: !Bool
- stgPipeline_allowTopLevelConApp :: Module -> DataCon -> [StgArg] -> Bool
  Is a top-level (static) StgConApp allowed or not. If not, use dynamic allocation.
  This is typically used to support dynamic linking on Windows and the -fexternal-dynamic-refs flag. See GHC.Stg.Utils.allowTopLevelConApp.
