[Lldb-commits] [PATCH] use std::atomic<> to protect variables being accessed by multiple threads

[Shawn Best]

There are several places where multiple threads are accessing the same variables simultaneously without any kind of protection.  I propose using std::atomic<> to make it safer.  I did a special build of lldb, using the google tool 'thread sanitizer' which identified many cases of multiple threads accessing the same memory.  std::atomic is low overhead and does not use any locks for simple types such as int/bool.
