Hi,
I would like to update LLVM, including clang, lld and lldb, to the
patch release version 5.0.1. They typically only do bugfixing, which
means that the diff to 5.0.0 is "only" about 3500 lines.
I don't expect any big fallout, but I would appreciate if someone
could do a ports run with this change. I will take care of src/x11
on amd64.
Update procedure is simply running
$ cd /usr/src/gnu/usr.bin/clang
$ make obj
$ make clean
$ make -j8
$ make install
Feedback appreciated!
Patrick

**LLVM_APPEND_VC_REV**:BOOL
Embed version control revision info (svn revision number or Git revision id).

- PACKAGE_VERSION macro). For this to work cmake must be invoked before the
- build. Defaults to ON.
+ The version info is provided by the ``LLVM_REVISION`` macro in

**LLVM_ENABLE_THREADS**:BOOL
Build with threads support, if available. Defaults to ON.
