I just wanted to point out that since another branch is coming, you may wish to wait until it arrives if you think a side-by-side comparison would be a good way of doing things. To clarify: that other branch won't be put up as a pull request, but we can decide how to proceed here if the general design shown in that other branch is preferred. I also mentioned that it will appear in a few days, but that's really dependent on the results of some more internal review. We're working hard on it!

The “No backend DTLTO” branch is ready. Please have a look and let us know what you think. https://github.com/romanova-ekaterina/llvm-project/pull/new/kromanova/main/integrated-DTLTO-no-backend
