[cfe-dev] How to deal with new build failures due to new warning? Was: Re: buildbot failure in LLVM on clang-with-lto-ubuntu

[Mehdi AMINI via cfe-dev]

Hi,

I would first revert it *now* because the bot needs to stay green *now*.

Then either the warnings can be fixed as a pre-commit to the added feature,
or if not possible the LLVM cmake config should first be updated to detect
and explicitly disable this warning.
