URL: https://github.com/llvm/llvm-project/commit/65d15fefe3392b1db2f679b3df029d43d8d26d2d DIFF: https://github.com/llvm/llvm-project/commit/65d15fefe3392b1db2f679b3df029d43d8d26d2d.diff LOG: [TargetList] Delete the destructor AFAICT, ~TargetList simply implements the default destructor, plus some locking. The history is murky, so I'm not sure why we do this locking. Perhaps, at some point, it was possible to delete the same TargetList instance from two different threads, setting up a race. If that were true, then the locking would protect against the race. Since TargetList is uniquely owned by Debugger (m_target_list), no such race is possible today.
