In other projects, you can add than since r221831, «lld now bootstraps on darwin» which is probably noteworthy ;-)

> ## News and articles from around the web
> 
> Chrome on Linux [now uses Clang for production
> builds](http://article.gmane.org/gmane.comp.compilers.clang.devel/39700).
> Clang has of course been used on OS X Chrome for quite some time. The switch
> saw reduction in binary size of ~8%, but this was vs GCC 4.6 rather than
> something more up-to-date.
> 
> The LLVM in HPC workshop at SC14 is taking place on Monday and the full agenda
> with abstracts [is available online](http://llvm-hpc-workshop.github.io/)
> 
> 
> ## On the mailing lists
> 
> * Duncan P.N. Exon Smith has posted an [RFC on splitting out metadata from the
> Value
> hierarchy](http://article.gmane.org/gmane.comp.compilers.llvm.devel/78738).
> There seems to be general support for the idea. If you have concerns, now is
> the time to speak up.
> 
> * Tom Stellard has posted a proposed [LLVM/Clang 3.5.1 release
> schedule](http://article.gmane.org/gmane.comp.compilers.llvm.devel/78752). RC1
> is currently planned for November 26th.
> 
> * Zachary Turner raised the issue [referencing Apple rdar bugs in commit
> messages](http://article.gmane.org/gmane.comp.debugging.lldb.devel/5710). The
> concern is that sometimes the commit messages are hard to work out without the
> context of the bug, which many of us do not have access to.

> [r221948](http://reviews.llvm.org/rL221948).
> 
> * Work has started on an assembler for the R600 backend.
