* Add support for tsan annotations (thread sanitizer, a valgrind-based tool).Nick Lewycky2011-11-141-0/+39
| | | | | | | | | | | | | These annotations are disabled entirely when either ENABLE_THREADS is off, or building a release build. When enabled, they add calls to functions with no statements to ManagedStatic's getters. Use these annotations to inform tsan that the race used inside ManagedStatic initialization is actually benign. Thanks to Kostya Serebryany for helping write this patch! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144567 91177308-0d34-0410-b5e6-96231b3b80d8

* Add the DataExtractor utility class.Benjamin Kramer2011-09-131-0/+111
| | | | | | | | | | It is an endian-aware helper that can read data from a StringRef. It will come in handy for DWARF parsing. This class is inspired by LLDB's DataExtractor, but is stripped down to the bare minimum needed for DWARF. Comes with unit tests! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139626 91177308-0d34-0410-b5e6-96231b3b80d8
