Law <law at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED CC| |law at redhat dot com Resolution|--- |DUPLICATE --- Comment #3 from Jeffrey A. Law <law at redhat dot com> --- I'm going mark this as a DUP of 82123. Ultimately the problem here is a lack of good range information in gimple-ssa-sprintf which is addressed by the same bits as 82123. WRT c#1 and the similarities with alloca warnings -- there's no good reason why the same technique we're going to use in the sprintf code couldn't also be used in the alloca code. We just convert it to a dom walker, embed the evrp analysis and query the evrp data. We should have a BZ to track this issue in gimple-ssa-warn-alloca. WRT c#2. I think the way to go will be to re-test once the fix for 82123 is installed and file bugs for anything still triggering the warning. *** This bug has been marked as a duplicate of bug 82123 ***
