FreeBSD 9.1: LLVM/Clang Battling GCC

Most users would never adjust defaults. "Defaults will prevail". So that's what >90% of users will actually be able to get from system. Hence it's completely fair and good idea to compare default systems without tuning.

Classic BSD:)

I agree that lack of support for something like OpenMP should not be hidden. But what is the point of benchmarking a not supported feature in a comparison? Just a waste of time, one could simply state that OpenMP is not supported instead.

Christ, are you guys bashing clang/BSD serious or am I just dropping into an exchange of in-jokes? I mean, this article is only relevant to you if you a) are running BSD and b) are interested in the performance impact of the clang switch. If you are not, then why are you wasting your and everyone else's time here debating non-issues?

They're just trolling. I've not idea why they do it.

Nobody but you is talking about the GPL here.

Besides that, after your pathetic and criminal outburst (accusing the OpenBSD people to be the Boston bombers) I am surprised that you are still allowed to post on this forum.

Also, anyone concerned with performance (or security or portability for that matter) would never use any BSD crap. So this article will never be used by BSD supports for what you claim. No they use it for trolling.

The people you accuse of bashing clang/BSD are good willed people trying to stop that from happening. BSD supporters are vile and blatent.



The real trolls in this thread are brainless BSD supporters like you, BitLight, vermanden, phkbsd, VertexSymphony and Vim_User. If there is one thing that can be improve in the conversation, it be your posts be invisible to others in threads similiar to this one.:)

Yes sir, you are back... Keep this thread alive so more people can be aware of the great things happening with FreeBSD. Thanks!

The irony here is that, compared to what we have in the Windows world, no one bothers with GCC. Slightly slower then MSVC, and a hack of a lot harder to, you know, CODE with.

As a developer, if I had to code for a non-Windows platform, I'd use LLVM/CLANG in a heartbeat over GCC, especially once it gains OpenMP support later this year.

See, that’s why I do not like the focus the OpenMP tests put on OpenMP: They create a hype on OpenMP which establishes the feeling that LLVM would be so much better than GCC if it just implemented OpenMP - which is simply a feature which will come at some point.

That’s like establishing a binary decision point when people should switch instead of showing the different aspects of choosing a compiler.

keep dreaming, more poeple use GCC then MSVC because it's free, portable and doesn't require the slow and bloated .NET to install. Your facts are twisted.

GCC is slower because it does more work it producing binaries that are smaller and more efficient then the horrible bloated messes produced by MSVC and CLANG. It makes more more sense: Compile once and run many times. Something the BSD homos don't get.

GCC outputs a lot more details that Clang and MSVC try to hide making it easiler to figure out the problem much more quickly.
