vectBndr :: Var -> VM VVar

Vectorise a binder variable, along with its attached type.

vectBndrNew :: Var -> FastString -> VM VVar

Vectorise a binder variable, along with its attached type, but give the result a new name.

vectBndrIn :: Var -> VM a -> VM (VVar, a)

Vectorise a binder then run a computation with that binder in scope.

vectBndrNewIn :: Var -> FastString -> VM a -> VM (VVar, a)

Vectorise a binder, give it a new name, then run a computation with that binder in scope.

vectBndrsIn :: [Var] -> VM a -> VM ([VVar], a)

Vectorise some binders, then run a computation with them in scope.

vectVar :: Var -> VM VExpr

Vectorise a variable, producing the vectorised and lifted versions.

vectPolyVar :: Var -> [Type] -> VM VExpr

Like `vectVar` but also add type applications to the variables.

vectLiteral :: Literal -> VM VExpr

Lifted literals are created by replicating them We use the the integer context in the `VM` state for the number of elements in the output array.
