We can build much smaller Mono runtime for .NET Core purposes by simply removing code we don't need in this configuration. We did a few easy initial steps but we can go much further.

This list is not comprehensive but parts like

• Culture Data
• Any PAL related code
• Unused icalls

The version and build number should be written to standard output with the reporting of other configuration information.

Adding this information to the output helps make comparison of results between different runs more meaningful and helps assure repeatability of test results. (In theory, it may not be meaningful to compare results from version N with results from version N+1.)

The compiler should analyze the function body to detect statements that are completely unreachable because of return and throw statements that cause a function to exit.

Consider the following example:

function main(...arguments)
    return 0
    print('Hello, world!')

In the above example, the print statement is never executed because main() is terminated before it can reach t
