Synopsis

Documentation

initV :: HscEnv -> ModGuts -> VectInfo -> VM a -> IO (Maybe (VectInfo, a))Source

Run a vectorisation computation.

Builtins

liftBuiltinDs :: (Builtins -> DsM a) -> VM aSource

Lift a desugaring computation using the Builtins into the vectorisation monad.

builtin :: (Builtins -> a) -> VM aSource

Project something from the set of builtins.

builtins :: (a -> Builtins -> b) -> VM (a -> b)Source

Lift a function using the Builtins into the vectorisation monad.

Variables

lookupVar :: Var -> VM (Scope Var (Var, Var))Source

Lookup the vectorised, and if local, also the lifted version of a variable.

  • If it's in the global environment we get the vectorised version. * If it's in the local environment we get both the vectorised and lifted version.

addGlobalScalarVar :: Var -> VM ()Source

Mark the given variable as scalar — i.e., executing the associated code does not involve any parallel array computations.

addGlobalScalarTyCon :: TyCon -> VM ()Source

Mark the given type constructor as scalar — i.e., its values cannot embed parallel arrays.
