So, as I start testing things locally with two additional changes (1. LTO by default 2. No ffunction/data-sections with LTO) we see: https://gist.github.com/trini/350ab850c42293563228b8d68a1bb89a as the detailed size reduction. This also shows that with LTO we want to turn off -ffunction-sections/etc as it's not useful now.
Tom, I have pushed another version to github PR to trigger CI, and am still working on clang. You can look at the github PR if you want to try yourself. I have also added patch that disables -ffunction-section/fdata-section on arm.
After I manage to make it all work in CI I will send v2 to mailing list.
