Usage options for $(basename $0) [--with-cc=arg [other options]]

Executing this script without any parameter will only run the default
configuration that has automatically been determined for the
architecture you're running.

    --with-cc=*             The compiler(s) to use for the tests
                            This is an option that will be iterated.

    --test-vs-mtest=*       Run test vs. mtest for '*' operations.
                            Only the first of each options will be
                            taken into account.

To be able to specify options a compiler has to be given with
the option --with-cc=compilername
All other options will be tested with all MP_xBIT configurations.

    --with-{m64,m32,mx32}   The architecture(s) to build and test
                            for, e.g. --with-mx32.
                            This is an option that will be iterated,
                            multiple selections are possible.
                            The mx32 architecture is not supported
                            by clang and will not be executed.

    --cflags=*              Give an option to the compiler,
                            e.g. --cflags=-g
                            This is an option that will always be
                            passed as parameter to CC.

    --make-option=*         Give an option to make,
                            e.g. --make-option="-f makefile.shared"
                            This is an option that will always be
                            passed as parameter to make.

    --with-low-mp           Also build&run tests with -DMP_{8,16,32}BIT.

    --mtest-real-rand       Use real random data when running mtest.

    --with-valgrind
    --with-valgrind=*       Run in valgrind (slow!).

    --limit-valgrind        Run with valgrind on CI only on specific branches.

    --valgrind-options      Additional Valgrind options
                            Some of the options like e.g.:
                            --track-origins=yes add a lot of extra
                            runtime and may trigger the 30 minutes
                            timeout.

Godmode:

    --all                   Choose all architectures and gcc and clang
                            as compilers but does not run valgrind.

    --format                Runs the various source-code formatters
                            and generators and checks if the sources
                            are clean.

    -h
    --help                  This message

    -v
    --version               Prints the version. It is just the number
                            of git commits to this file, no deeper
                            meaning attached

The following list shows the discrepancy between
the shared library and the Windows dynamic library.
To fix this error, one of the following things
has to be done:
* the script which generates tommath.def has to be modified
    (function generate_def() in helper.pl).
* The exported symbols are really different for some reason
    This has to be manually investigated.
