isFun :: Fresh m => HashMap TyConOccName TyCon -> Term -> m Bool Source #

Does a term have a function type?

isPolyFun :: Fresh m => HashMap TyConOccName TyCon -> Term -> m Bool Source #

Does a term have a function or polymorphic type?

isLam :: Term -> Bool Source #

Is a term a term-abstraction?

isLet :: Term -> Bool Source #

mkVec Source #

Arguments

:: DataCon

The Nil constructor

-> DataCon

The Cons (:>) constructor

-> Type

Element type

-> Integer

Length of the vector

-> [Term]

Elements to put in the vector

-> Term 

Create a vector of supplied elements

appendToVec Source #

Arguments

:: DataCon

The Cons (:>) constructor

-> Type

Element type

-> Term

The vector to append the elements to

-> Integer

Length of the vector

-> [Term]

Elements to append

-> Term 

Append elements to the supplied vector

extractElems Source #

Arguments

:: DataCon

The Cons (:>) constructor

-> Type

The element type

-> Char

Char to append to the bound variable names

-> Integer

Length of the vector

-> Term

The vector

-> [(Term, [LetBinding])] 

Create let-bindings with case-statements that select elements out of a vector. Returns both the variables to which element-selections are bound and the let-bindings

extractTElems Source #

Arguments

:: DataCon

The LR constructor

-> DataCon

The BR constructor

-> Type

The element type

-> Char

Char to append to the bound variable names

-> Integer

Depth of the tree

-> Term

The tree

-> ([Term], [LetBinding]) 

Create let-bindings with case-statements that select elements out of a tree. Returns both the variables to which element-selections are bound and the let-bindings

mkRTree Source #

Arguments

:: DataCon

The LR constructor

-> DataCon

The BR constructor

-> Type

Element type

-> Integer

Depth of the tree

-> [Term]

Elements to put in the tree

-> Term 

Create a vector of supplied elements

isSignalType :: HashMap TyConOccName TyCon -> Type -> Bool Source #

Determine whether a type is isomorphic to Clash.Signal.Internal.Signal'

It is i.e.:

  • Signal' clk a
  • (Signal' clk a, Signal' clk b)
  • Vec n (Signal' clk a)
  • data Wrap = W (Signal clk' Int)
  • etc.
