Testing #LLVM snapshots for #Gentoo be like:
1. You build and test LLVM. It turns out that Clang fails at CMake time. Regression was introduced by a corporate employee on Friday, with no review and only a link to the internal Apple bug tracker. You submit a patch.
https://github.com/llvm/llvm-project/pull/86386
2. You go back a day, just before the breaking change, and start over. You build and test all LLVM components, only to discover at the very last package that OpenMP was broken, roughly an hour earlier. You submit a patch.
https://github.com/llvm/llvm-project/pull/86397
3. You go back prior to that commit, and start over. Fortunately, CCache saves you from rebuilding everything from scratch. Still, many hours of testing are ahead of you. You really hope for no more regressions…
