Worked for 3 months on Porting Undefined Behavior Sanitizer (UBSan) to a Qualcomm Proprietary Microcontroller. According to language standards of C, C++ there are certain commands that are kept undefined. It leaves the understanding of code vague but also allows for positives like machine dependent optimizations. UBSan detects such behavior at runtime by adding additional UBSan calls at compile time. Work involved working with Clang, LLVM toolchains, Cmake, Linux etc.
