exception handling optimization

Hello LLVM devs,

I would like to start a project to optimize exception handling in clang. If anyone in interested in helping, please let me know.


Maybe you could start by writing a RFC describing the rationale, the
approach, etc.?

Ok awesome. I don’t feel I understand LLVM well enough yet to describe the approach, but the rationale would basically be to bring exceptions closer to obeying the zero-overhead principle. I’ll keep researching and keep in touch,
