Has anyone tried clang's ThreadSanitizer with Intel Threading Building Blocks (TBB)?
My experience so far was that you will get a lot of warnings, even for relatively simple examples. Unfortunately, many of them seem to be false positives.
In this answer to another ThreadSanitizer question, suppression files are recommended. Could that help? Is there a suppression file for TBB or any other technique?
(Side note: With Helgrind, it looks similar. Many false positives.)
I only got it working when I reference the suppression file in
TSAN_OPTIONS. At least for me, only referencing in during compilation with
-fsanitize-blacklist did not work with the environment variable.
Anyway, here is a possible suppression file
# sanitizer-thread-suppressions.txt race:^tbb*
... and that is how you can use it:
If you increase verbosity, you should see outputs like these:
TSAN_OPTIONS="verbosity=2 suppressions=sanitizer-thread-suppressions.txt" ./my_binary ... ThreadSanitizer: matched suppression '^tbb*'
