Anyone knows about a testcase which was fixed by Wed Dec 24 18:05:13 1997 SPARC change?

[Richard Kenner]

    This brings to mind one benefit of having Ada checked into the gcc
    repository.  If it were in, and if your checkin log messages named the
    testcase, then someone could run that one testcase after making what
    they think is the right change.

But the test cases can't be in the repository since they are almost
always proprietary code of some customer.
