Optimization remarks are logs of Clang's optimization passes, describing optimization attempts and failures - which might be mitigated. Sometimes. Deciphering them might seem a matter for compiler authors, but we can kick-start this effort together.
About 50% of the talk would be dedicated to practical examples of missed optimizations and mitigations - with emphasis on alias analysis and escape-analysis. We will also discuss other compilers and even other languages.
