readGEnv :: (GlobalEnv -> a) -> VM aSource

Project something from the global environment.

setGEnv :: GlobalEnv -> VM ()Source

Set the value of the global environment.

updGEnv :: (GlobalEnv -> GlobalEnv) -> VM ()Source

Update the global environment using the provided function.

Vars

defGlobalVar :: Var -> Var -> VM ()Source

Add a mapping between a global var and its vectorised version to the state.

Vectorisation declarations

lookupVectDecl :: Var -> VM (Maybe (Type, CoreExpr))Source

Check whether a variable has a (non-scalar) vectorisation declaration.

noVectDecl :: Var -> VM BoolSource

Check whether a variable has a NOVECTORISE declaration.

Scalars

globalScalarVars :: VM VarSetSource

Get the set of global scalar variables.

isGlobalScalarVar :: Var -> VM BoolSource

Check whether a given variable is in the set of global scalar variables.

globalScalarTyCons :: VM NameSetSource

Get the set of global scalar type constructors including both those scalar type constructors declared in an imported module and those declared in the current module.

TyCons

lookupTyCon :: TyCon -> VM (Maybe TyCon)Source

Lookup the vectorised version of a TyCon from the global environment.

defTyConName :: TyCon -> Name -> TyCon -> VM ()Source

Add a mapping between plain and vectorised TyCons to the global environment.

The second argument is only to enable tracing for (mutually) recursively defined type constructors, where we must not pull at the vectorised type constructors (because that would pull too early at the recursive knot).

defTyCon :: TyCon -> TyCon -> VM ()Source

Add a mapping between plain and vectorised TyCons to the global environment.

globalVectTyCons :: VM (NameEnv TyCon)Source

Get the set of all vectorised type constructors.

Datacons

lookupDataCon :: DataCon -> VM (Maybe DataCon)Source

Lookup the vectorised version of a DataCon from the global environment.

defDataCon :: DataCon -> DataCon -> VM ()Source

Add the mapping between plain and vectorised DataCons to the global environment.

PA Dictionaries

lookupTyConPA :: TyCon -> VM (Maybe Var)Source

Lookup the PA dfun of a vectorised type constructor in the global environment.

defTyConPAs :: [(TyCon, Var)] -> VM ()Source

Associate vectorised type constructors with the dfun of their PA instances in the global environment.
