I'd have to do more archive search on llvm-dev at lists.llvm.org (or cfe-dev at lists.llvm.org), but some info:

- https://llvm.org/docs/TestingGuide.html#test-suite : note how we intentionally kept the e2e test-suite separated from the compiler, and consider that changes to the compiler should have unit-tests independent of the test-suite.
- here is the most recent thread on the topic I believe: https://lists.llvm.org/pipermail/llvm-dev/2019-October/thread.html#135739
- here is a long thread that may show how we approach such changes in the project: https://lists.llvm.org/pipermail/llvm-dev/2016-February/095300.html

This was discussed a few time before that of course over the lifetime of the project, it's just hard to find all the discussions on the topic.
