We have not seen any of those problems, perhaps because our work is new development, and our architecture avoids large files and subunits, but we have seen other little bugs. The Booch Components for Ada 95 would not compile under 1.8.8, but everything seems to be fine now. There were also problems with exception handling (especially with some of the new exception features in Ada 95) and bit arrays. To Green Hills' credit, they have been very responsive to our problem reports, giving us prerelease patches as needed to keep us up and running. For our part, we've done our best to isolate problems before reporting them, to help them get to the problem faster. > Have we progressed in the new features of Ada95 where we are starting to > exceed the capabilities of the compiler vendors? I have been surprised at some of the problems. I would have expected a validation suite to catch most of them. Some of the problems have been in their back end, some appear to have been in the Intermetrics front-end, and in one case what we thought was a Green Hills bug was the GNAT compiler being more permissive than the reference manual. > I'm not picking on Green Hills because I think they have a poor product. > We're using it at work on multiple projects and everyone is a little > "gun-shy" when they hear about problems.

It has taken us a while to get accustomed to both AdaMULTI and VxWorks -- embedded development is a new experience for most of us -- but the Green Hills product works well with the VxWorks target and (hooray) has a command line interface, too. And I'll agree that their support folks have been very helpful. ------------------------------------------------------------------------- Mike Bates FlightSafety Simulation Staff Engineer [log in to unmask] 2700 North Hemlock Circle Computer Systems Group 918-259-5598 Broken Arrow, Oklahoma 74012 -------------------------------------------------------------------------
