I think I'm having a hard time reviewing these patches because I'm not confident of the design. I've started writing up the current state of the new pass manager for codegen and will send it out to LLVM discourse in hopes of more eyes and discussion on the high-level design, and people can hopefully agree on something. I will try my hardest to finish the RFC and send it out next week. Sorry for the slow responses
