  • operands Default implementation

    The operands of the instruction.

  • Replaces the operand at position i with o.

    Do not call this method directly. Use Module.replaceUses(of:with:) instead to ensure def-use ensure def-use chains are kept updated.

    Declaration

    Swift

    mutating func replaceOperand(at i: Int, with new: Operand)

  • isTransparentOffset Extension method

    true iff self is an instruction computing an address derived from its operand without accessing them.

    Declaration

    Swift

    fileprivate var isTransparentOffset: Bool { get }

  • isAccess(_:) Extension method

    Returns true iff self is an access [k] instruction.

    Declaration

    Swift

    func isAccess(_ k: AccessEffect) -> Bool
    Show on GitHub
  • isAccess(in:) Extension method

    Returns true iff self is an access k instruction where k is subset of ks.

    Declaration

    Swift

    func isAccess(in ks: AccessEffectSet) -> Bool
