Regression tests (The GNU Modula-2 Compiler)

### 2.26 Regression tests for gm2 in the repository ¶

The regression testsuite can be run from the gcc build directory:

    $ cd build-gcc
    $ make check -j 24

which runs the complete testsuite for all compilers using 24 parallel invocations of the compiler. Individual language testsuites can be run by specifying the language, for example the Modula-2 testsuite can be run using:

    $ cd build-gcc
    $ make check-m2 -j 24

Finally the results of the testsuite can be emailed to the gcc-testresults list using the `test_summary` script found in the gcc source tree:

    $ ‘directory to the sources’/contrib/test_summary
