James, The PIWG suite contains no tests of Ada 95 features, and there are no plans to update it. The PIWG suite should be considered obsolete. So far as I know, there are no published results of ACES measurements. My team responsible for the ACES upgrade to Ada 95 was not permitted to publish test results. I'm not sure what you mean by "comparison with Ada 83". The ACES Single System Analysis program does provide some comparisons of the Ada 95 way and the Ada 83 way of doing a few things, if you run all the appropriate tests on the same system. If you are interested in PIWG-like results, get the Quick-Look subset of the ACES and do some tests with it. (See http://sw-eng.falls-church.va.us/AdaIC/testing/aces" or FTP to sw-eng.falls-church.va.us, directory public/AdaIC/testing/aces.) If you are interested in doing full-up Ada testing and need support, CTA can supply that support. (Other organizations might be able to do the same.) For quick questions, feel free to call me.
