How do we know the final compiler will work? What should its development focus on? Explain.
The resulting compiler can be evaluated and validated using a combination of testing methodologies such as unit testing, integration testing, system testing, and acceptability testing. These testing methodologies strive to ensure that the compiler performs as expected and meets the needs of the user.
To create a working final compiler, the development team should concentrate on the following areas:
1)Correctness: The compiler should transform the source code into the target language appropriately. The compiler's accuracy can be confirmed by comparing the output of the produced code to the expected result.
2)Performance: The compiler should be fast and efficient. Compiling the source code should not require an inordinate amount of time. Benchmarking the compiler against other compilers can be used to assess its performance.
3)Robustness: The compiler should be able to gracefully handle failures and unexpected inputs. It should be able to provide informative error messages that assist the user in fixing the code. The compiler's robustness can be checked by inserting various types of defects into the source code and ensuring that the compiler identifies and reports them accurately.
