In this article, we investigate how standard compiler code transformations, performed at the compiler intermediate representation, affect such representation and consequently the performance. Our research targets clang/LLVM, a popular compiler infrastructure. Our experimental evaluation demonstrates how several code transformations change the intermediate representation and consequently improve the target code's performance in terms of runtime.
