def Lean.Compiler.LCNF.isCompilerRelevantMData (_mdata : Lean.MData) : Bool

Return true if mdata should be preserved. Right now, we don't preserve any MData, but this may change in the future when we add support for debugging information

Equations

• Lean.Compiler.LCNF.isCompilerRelevantMData _mdata = false

def Lean.Compiler.LCNF.isLcCast? (e : Lean.Expr) : Option Lean.Expr

Return true if e is a lcCast application.

Equations

• Lean.Compiler.LCNF.isLcCast? e = if Lean.Expr.isAppOfArity e `lcCast 3 = true then some (Lean.Expr.appArg! e) else none

structure Lean.Compiler.LCNF.CasesInfo : Type

Store information about casesOn declarations.

We treat them uniformly in the code generator.

• declName : Lake.Name
• arity : Nat
• numParams : Nat
• discrPos : Nat
• altsRange : Std.Range
• altNumParams : Array Nat
• motivePos : Nat

def Lean.Compiler.LCNF.CasesInfo.numAlts (c : Lean.Compiler.LCNF.CasesInfo) : Nat

Equations

• Lean.Compiler.LCNF.CasesInfo.numAlts c = Array.size c.altNumParams

def Lean.Compiler.LCNF.builtinRuntimeTypes : List Lake.Name

List of types that have builtin runtime support

Equations

• Lean.Compiler.LCNF.builtinRuntimeTypes = [`String, `UInt8, `UInt16, `UInt32, `UInt64, `USize, `Float, `Thunk, `Task, `Array, `ByteArray, `FloatArray, `Nat, `Int]

def Lean.Compiler.LCNF.isRuntimeBultinType (declName : Lake.Name) : Bool

Return true iff declName is the name of a type with builtin support in the runtime.

Equations

• Lean.Compiler.LCNF.isRuntimeBultinType declName = List.contains Lean.Compiler.LCNF.builtinRuntimeTypes declName
