PrettyStackTraceHead is a LLVM_THREAD_LOCAL, which means it's just a global in LLVM_ENABLE_THREADS=NO builds. If a CrashRecoveryContext is used with code that uses PrettyStackEntries, and a crash happens, PrettyStackTraceHead is currently not reset to its pre-crash value. These functions make it possible to add a cleanup to such code that does this. (Not reseting the value then causes the assert in ~PrettyStackTraceEntry() to fire if the code outside of the CrashRecoveryContext also uses PrettyStackEntries -- for example, clang when building a module.) Part of PR11974. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@244338 91177308-0d34-0410-b5e6-96231b3b80d8
