I'm not quite sure what your point is. But I think Richard was comparing a
compiler that was conformity tested against one that was not. So, such a
system wouldn't have been tested against any test suite.

Of course, in actual practice, there is a continuum of testing practice,
from formal conformity assessment to completely untested. I doubt that there
are many commercial systems on either extreme of that continuum, but Ada
systems tend to be close to the formally tested end.
