      • prepScalarLabel

        public String prepScalarLabel()
        Function to prepare label for scalar inputs while generating instructions. It attaches placeholder suffix and prefixes if the Lop denotes a variable.
        Returns:
        prepared scalar label

      • prepScalarOperand

        public String prepScalarOperand​(Types.ExecType et,
                                String label)
        Function to be used in creating instructions for creating scalar operands. It decides whether or not attach placeholders for instruction patching. Resulting string also encodes if the operand is a literal. For non-literals: Placeholder prefix and suffix need to be attached for Instruction Patching during execution. However, they should NOT be attached IF: - the operand is a literal OR - the execution type is CP. This is because CP runtime has access to symbol table and the instruction encodes sufficient information to determine if an operand is a literal or not.
        Parameters:
        et - execution type
        label - instruction label
        Returns:
        prepared scalar operand
