    • valueOf Link icon

      public static NopOpGen valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
    • generateRunCode Link icon

      public void generateRunCode(JitCodeGenerator gen, JitOp op, JitControlFlowModel.JitBlock block, org.objectweb.asm.MethodVisitor rv)
      Description copied from interface: OpGen
      Emit bytecode into the run method.

      This method must emit the code needed to load any input operands, convert them to the appropriate type, perform the actual operation, and then if applicable, store the output operand. The implementations should delegate to JitCodeGenerator.generateValReadCode(JitVal, JitTypeBehavior), JitCodeGenerator.generateVarWriteCode(JitVar, JitType), and TypeConversions appropriately.

      Specified by:
      generateRunCode in interface OpGen<JitOp>
      Parameters:
      gen - the code generator
      op - the p-code op (use-def node) to translate
      block - the basic block containing the p-code op
      rv - the visitor for the run method.
