|  | Historically this directory has been a home for Valgrind and ThreadSanitizer. | 
|  | Since then other memory tools used in Chromium started squatting here and the | 
|  | name became confusing. | 
|  | We're replacing tools/valgrind with tools/memory/ new tools should go there. | 
|  |  | 
|  | Attention: ThreadSanitizer v1 has been retired and files in this dir | 
|  | should not be used anymore. Please refer to | 
|  | http://dev.chromium.org/developers/testing/threadsanitizer-tsan-v2 | 
|  | for the instructions on using ThreadSanitizer v2. | 
|  | Namely, the suppressions now reside in base/debug/tsan_suppressions.cc |
