class Lean.Compiler.LCNF.MonadCodeBind (m : Type → Type) : Type

Helper class for lifting CompilerM.codeBind

• codeBind : Lean.Compiler.LCNF.Code → (Lean.FVarId → m Lean.Compiler.LCNF.Code) → m Lean.Compiler.LCNF.Code

@[inline, reducible]

abbrev Lean.Compiler.LCNF.Code.bind {m : Type → Type} [Lean.Compiler.LCNF.MonadCodeBind m] (c : Lean.Compiler.LCNF.Code) (f : Lean.FVarId → m Lean.Compiler.LCNF.Code) : m Lean.Compiler.LCNF.Code

Return code that is equivalent to c >>= f. That is, executes c, and then f x, where x is a variable that contains the result of c's computation.

If c contains a jump to a join point jp_i not declared in c, we throw an exception because an invalid block would be generated. It would be invalid because f would not be applied to jp_i. Note that, we could have decided to create a copy of jp_i where we apply f to it, by we decided to not do it to avoid code duplication.
