Generic Data Type

NOTE: Type is not included in the generic datatype. However, we could have included it and provided the facility for descending into types. We have not done so because (a) we do not need that functionality, and (b) the types are complicated and we're not sure that we understand them.

data Core

Core is the sum type of all nodes in the AST that we wish to be able to traverse. All Node instances in HERMIT define their Generic type to be Core.

data CoreDef

A (potentially recursive) definition is an identifier and an expression. In GHC Core, recursive definitions are encoded as (Id, CoreExpr) pairs. This data type is isomorphic.

GHC Core Extras

type CoreTickish = Tickish Id

Unlike everything else, there is no synonym for Tickish Id provided by GHC, so we provide one.

defToRecBind :: [CoreDef] -> CoreBind

Convert a list of recursive definitions into an (isomorphic) recursive binding group.
