readLEnv :: (LocalEnv -> a) -> VM a

Project something from the local environment.

setLEnv :: LocalEnv -> VM ()

Set the local environment.

updLEnv :: (LocalEnv -> LocalEnv) -> VM ()

Update the enviroment using the provided function.

localV :: VM a -> VM a

Perform a computation in its own local environment. This does not alter the environment of the current state.

closedV :: VM a -> VM a

Perform a computation in an empty local environment.

getBindName :: VM FastString

Get the name of the local binding currently being vectorised.

inBind :: Id -> VM a -> VM a

Run a vectorisation computation in a local environment, with this id set as the current binding.

lookupTyVarPA :: Var -> VM (Maybe CoreExpr)

Lookup a PA tyvars from the local environment.

defLocalTyVar :: TyVar -> VM ()

Add a tyvar to the local environment.

defLocalTyVarWithPA :: TyVar -> CoreExpr -> VM ()

Add mapping between a tyvar and pa dictionary to the local environment.

localTyVars :: VM [TyVar]

Get the set of tyvars from the local environment.
