freebsd-dev/contrib/llvm/tools/llvm-readobj/COFFDumper.cpp
Dimitry Andric f785676f2a Upgrade our copy of llvm/clang to 3.4 release. This version supports 
all of the features in the current working draft of the upcoming C++
standard, provisionally named C++1y.

The code generator's performance is greatly increased, and the loop
auto-vectorizer is now enabled at -Os and -O2 in addition to -O3.  The
PowerPC backend has made several major improvements to code generation
quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ
backends have all seen major feature work.

Release notes for llvm and clang can be found here:
