Not at all irrelevant: this proposal is about changing the default compiler for the FreeBSD system itself, not for all software out there. If certain software performs significantly better with gcc, and using newer versions of the GPL is no problem, then it is obviously the better choice. However, I think the majority of users can get by just fine using clang, right now. Doug Barton even confirmed in this thread that 80% of our ports already work with it! > What is important is whether software built with clang functions > correctly.

It is currently not really a high priority item for upstream. This is obviously something that a certain part of our userbase will care a lot about, while most of the time they won't care so much about licensing or politics. So those people are probably better off using gcc for the time being. > Has anyone run Spec CPU2006 on i386 and amd64 FreeBSD? I am not aware of it, but is that test available publicly? I might take a shot, if I can get my hands on it.Received on Tue Sep 11 2012 - 12:10:14 UTC
