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 : Phase

  Which phase this Pass is supposed to run in

• phaseOut : Phase

  Resulting phase.

• phaseInv : self.phaseOut ≥ self.phase
• shouldAlwaysRunCheck : Bool

  Whether IR validation checks should always run after this pass, regardless of configuration options.

• name : Name

  The name of the Pass

• run : Array (Decl self.phase.toPurity) → CompilerM (Array (Decl self.phaseOut.toPurity))

  The actual pass function, operating on the Decls.

instance Lean.Compiler.LCNF.instInhabitedPass : Inhabited Pass

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.

• phase : Phase

  Affected phase.

• install : Array Pass → CoreM (Array 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.

structure Lean.Compiler.LCNF.PassManager : Type

The PassManager used to store all Passes that will be run within pipeline.

• basePasses : Array Pass

  Passes that happen during the LCNF base phase

• monoPasses : Array Pass

  Passes that happen during the LCNF mono phase before lambda lifting

• monoPassesNoLambda : Array Pass

  Passes that happen during the LCNF mono phase after lambda lifting. Note that lifted lambdas will have been lifted out of the SCC they originated from if possible.

• impurePasses : Array Pass

  Passes that happen during the LCNF impure phase.
