     31   RaceVerifier is a tool for verifying race reports produced by ThreadSanitizer.
     32   It works by adding time delays after potentially racey instructions and making
     33   sure that they are executed simultaneously.
     34 
     35   To use RaceVerifier, save the stderr log of a ThreadSanitizer run to a file
     36   and run tsan again with --race-verifier=<log file name> option.
