I think it might be worthwhile to pursue later on, rather than now, when everyone is just coming back from the new year's celebrations and probably have a lot of other work to deal with. Just in case I misunderstood you, by Project do you just mean setting some time aside at a later date to work on all the issues, likely the build team's responsibility, or do you mean an actual full fledged OpenJDK Project, one that has to be proposed by someone on the discuss mailing list and voted on, with a full blown Lead, Reviewers, Committers, and so on, like, for instance, mobile or Leyden?
With all that aside, I find it a bit humorous that Windows/gcc, the very OS that is often claimed to have broken LTO with gcc, seems to be the only OS+compiler combination that has a working LTO HotSpot :P (All GTests except the ones regarding debug symbols pass perfectly, the debug symbol GTests don't pass because gcc does not have proper support for codeview debugging information yet) best regards, Julian
