This project is the home for Sanitizers: AddressSanitizer, MemorySanitizer, ThreadSanitizer, LeakSanitizer, and more. The actual code resides in the LLVM repository. Here we keep extended documentation, bugs and some helper code.
The documentation for our tools:
- AddressSanitizer (detects addressability issues) and LeakSanitizer (detects memory leaks)
- ThreadSanitizer (detects data races and deadlocks) for C++ and Go
- MemorySanitizer (detects use of uninitialized memory)
- HWASAN, or Hardware-assisted AddressSanitizer, a newer variant of AddressSanitizer that consumes much less memory
- UBSan, or UndefinedBehaviorSanitizer
Some of the sanitizers are also available for different OS Kernels:
