structure Lean.Compiler.LCNF.Pass : Type

A single compiler Pass, consisting of the actual pass function operating on the Decls as well as meta information.

• occurrence : Nat

  Which occurrence of the pass in the pipeline this is. Some passes, like simp, can occur multiple times in the pipeline. For most passes this value does not matter.

• phase : Lean.Compiler.LCNF.Phase

  Which phase this Pass is supposed to run in

• phaseOut : Lean.Compiler.LCNF.Phase

  Resulting phase.

• phaseInv : self.phaseOut ≥ self.phase
• name : Lake.Name

  The name of the Pass

• run : Array Lean.Compiler.LCNF.Decl → Lean.Compiler.LCNF.CompilerM (Array Lean.Compiler.LCNF.Decl)

  The actual pass function, operating on the Decls.

structure Lean.Compiler.LCNF.PassInstaller : Type

Can be used to install, remove, replace etc. passes by tagging a declaration of type PassInstaller with the cpass attribute.

• install : Array Lean.Compiler.LCNF.Pass → Lean.CoreM (Array Lean.Compiler.LCNF.Pass)

  When the installer is run this function will receive a list of all current Passes and return a new one, this can modify the list (and the Passes contained within) in any way it wants.
