Hi all.
Is anybody aware of regressions in the optimizer on x86_64?
With latest SVN, my code runs nicely up to -O1, but goes haywire on -O2. This
is not the case for 4.3.2 (both checkouts from 20080629).
Any pointers to PRs or how to (easily) track down the offending option and
code are be highly welcome. I think I did not go for optimizer problems
before ...
Thanks
Daniel
