            Bug ID: 15935
           Summary: 3.3 rc1 testing result
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW

I did an LTO bootstrap and most things work. The issues I know of that I think
need to be fixed before the release are:

* Bug 15882 is present. r181286 needs to be ported.
* With optimizations clang will still "miscompile"

extern "C" {
  __attribute__((used)) static void f() {
  }
}

by not having a 'f' symbol. I say "miscompile" because that is not actually
required by the standard, but has the potential to break quiet a bit of code.

The patch to fix this in under review at
