Synopsis

Documentation

Constructors

StgPipelineOpts
Fields 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

Optional Stg-to-Stg passes.

Constructors

StgCSE	Common subexpression elimination
StgLiftLams StgLiftConfig	Lambda lifting closure variables, trading stack/register allocation for heap allocation
StgStats
StgUnarise	Mandatory unarise pass, desugaring unboxed tuple and sum binders
StgBcPrep	Mandatory when compiling to bytecode
StgDoNothing	Useful for building up `getStgToDo`
