The SIGAda PIWG links are no good in part because PIWG was "unchartered"
several years ago, due to lack of interest. I was the last PIWG chair.
I still have the last version of the ACES, along with experience in using it
(though that experience is rusty). Some of you may remember that I led the
last set of changes in the ACES, while working for another company.

For an overview, see
Note that the SIGAda PIWG (Performance Issues Working Group)
links aren't much good as they point to the old Ada IC's
Falls Church address.
The Ada Compiler Evaluation Suite should be helpful, see
