      the start of the instruction range
    • endScope

      Label endScope()
      Returns the end of the instruction range.
      Returns:
      the end of the instruction range
    • characterRangeStart

      int characterRangeStart()
      Returns the encoded start of the character range region (inclusive). The value is constructed from the line_number/column_number pair as given by line_number << 10 + column_number, where the source file is viewed as an array of (possibly multi-byte) characters.
      Returns:
      the encoded start of the character range region (inclusive)
    • characterRangeEnd

      int characterRangeEnd()
      Returns the encoded end of the character range region (exclusive).. The value is constructed from the line_number/column_number pair as given by line_number << 10 + column_number, where the source file is viewed as an array of (possibly multi-byte) characters.
