Optimization Remarks - "Remarks Helping the Compiler Generate Better Code"
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 will 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.

A Mathematics MA by training, but a 20Y C++ developer, writer, and speaker in both the Linux and MS universes. Member of the maintainer's team of Compiler-Explorer (==godbolt). Fascinated by compilers, debuggers, and pretty much anything low-level. Fiercely hated by his cat for no apparent reason.
