Worked on the espressif/llvm-project repository to enhance AddressSanitizer by implementing suppression for alloc-dealloc-mismatch errors. Developed stack-based suppression logic and introduced a dedicated suppression type, allowing the sanitizer to reduce false positives related to allocation and deallocation mismatches. Expanded end-to-end test coverage to verify suppression behavior and prevent future regressions, contributing to more stable continuous integration and improved developer productivity. All changes were implemented in C++ with a focus on compiler development, debugging tools, and memory safety. The work addressed sanitizer noise, making debugging more efficient and ensuring that allocation mismatch issues are handled more reliably in the codebase.
