`__thread` doesn't exist on Windows, and neither does `thread_local`. `ThreadLocal<T>` in llvm is the only thing I know that works everywhere. Once I get the Python 3 stuff finished, we can move to MSVC 2015, which *does* support `thread_local`. Then we can use the `LLDB_THREAD_LOCAL` define as you suggest. Does that work for everyone? http://reviews.llvm.org/D13940 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
