def Lean.Compiler.LCNF.Simp.attachCodeDecls (decls : Array Lean.Compiler.LCNF.CodeDecl) (code : Lean.Compiler.LCNF.Code) :
Lean.Compiler.LCNF.Simp.SimpM Lean.Compiler.LCNF.Code

Attach the given decls to code. For example, assume decls is #[.let _x.1 := 10, .let _x.2 := true], then the result is

let _x.1 := 10
let _x.2 := true
