--- Comment #4 from Jan Hubicka <hubicka at ucw dot cz> 2010-09-28 12:06:39 UTC --- Hi, the contant folding in tree-ssa-ccp has several bugs in it concerning to arrays with non-0 low bounds. This happens in Ada and fortran and since fortran produces array constructors that the code confuses in a way that we don't fold most of time, Ada is probably only one affected. I rewrote the code but the patch took a while to settle since it is quite touchy area. I am just doing final testing and will commit it shortly. Hopefully it will fix both the problems. If not, we need to figure out what Ada does special about static constructors - this would seem more like a frontend bug. Honza
