Just before the end of the quarter, we have updated + clang, llvm and lldb in base to 3.6.0 release. These all + contain numerous improvements; please see the linked release + notes for more detailed information.

+ +

We have also imported a newer snapshot of compiler-rt, + with better support for Address Sanitizer and Undefined + Behavior Sanitizer. With the updated clang, llvm, and + compiler-rt, we now support the Address Undefined Behavior + Sanitizers in the base system toolchain.

+ +

Like the 3.5.0 release, these components require C++11 + support to build. At this point, FreeBSD 10.0 and later + provide that support, at least on x86.

+ +

It is still unclear whether we will be able to MFC this + to any stable branches, due to the difficulty it will + introduce for upgrading from a system without C++11 support, + either older releases or architectures still using gcc.

+ +

In the lld-import branch, we have also imported a recent + snapshot of lld, a linker produced by the LLVM project. This + is a very preliminary effort of making it available as a + system linker.

+ +

Thanks to Ed Maste, Roman Divacky, Andrew Turner and + Davide Italiano for their help with this import, and thanks to + Antoine Brodin for performing a ports exp-run.

+ + + + +

After the ports exp-run, a small number of ports + turned out to have problems, and for almost all of these, PRs + with fixes or workarounds were filed. While most of these PRs + have been processed and closed, there are still a few left + that need attention, from either the maintainer(s) or other + volunteers.

+ + + +

Andrew Turner is working on bringing up the arm64 + architecture, which is now fully supported in clang and llvm. + This will be a very interesting new area for solving + challenging problems.

+ + + +

There are still issues with the powerpc and sparc64 + architectures, and any help in these areas is very much + appreciated.
