What are the differences between ThreadSanitizer and Helgrind?
ThreadSanitizer is a dynamic data race detector that works at runtime, while Helgrind is a Valgrind tool that detects data races during program execution. ThreadSanitizer is generally faster and can provide more detailed reports.
Which one is better for C++ applications?
It depends on your needs. ThreadSanitizer is often preferred for C++ due to its speed and integration with compilers like GCC and Clang. Helgrind can be more thorough but may slow down execution.
Can they be used together?
Yes, you can use both tools in different stages of development. For example, use ThreadSanitizer during initial testing and Helgrind for a more in-depth analysis.
What are some common issues they can detect?
Both tools can detect data races, deadlocks, and other concurrency issues. ThreadSanitizer is particularly good at identifying race conditions.
