no_sanitize
The tracking issue for this feature is: #39699
The no_sanitize
attribute can be used to selectively disable sanitizer instrumentation in an annotated function. This might be useful to: avoid instrumentation overhead in a performance critical function, or avoid instrumenting code that contains constructs unsupported by given sanitizer.
The precise effect of this annotation depends on particular sanitizer in use. For example, with no_sanitize(thread)
, the thread sanitizer will no longer instrument non-atomic store / load operations, but it will instrument atomic operations to avoid reporting false positives and provide meaning full stack traces.
