Patch for LLVM

Hi, I would like to submit a small patch to LLVM. I would like to explain the idea first. So, I should subscribe to llvm-dev mailing list and send my idea and patch there first? What are the ideal steps?
Thanks!

It depends on the scope of the patch, most patch don’t start with a llvm-dev@ thread, but if you’re unsure this is always welcome.
llvm-dev@ registration is a bit problematic right now because of spam, see instructions on this page: llvm-dev Info Page

I would like to patch the file cmake/modules/AddOCaml.cmake to help OCaml bindings produce additional helper *.cmt files. Where should I start submission?

The easiest is likely to send the patch to our Phabricator instance: Code Reviews with Phabricator — LLVM 12 documentation ; you can log in there using a GitHub account.

Thanks, I will try that
