Today for the first time I was able to compile my complete POOMA based application with tree-ssa (on a machine with a reasonable amount of memory - 1GB was not enough until recently). If this were my first try, I'd say "go ahead and merge" - because the remaining compile and runtime regressions are likely to be addressed. But of course with the mixed experience I made in the past I'm inclined to hold off the merge for some more time. Oh, and of course, f.i. ia64 doesn't bootstrap on the branch for quite some time now. Keep it going! Richard.
