<div dir="ltr">Thanks everyone. I will move forward with a pitch as part of the proposal process.<div><br></div><div>The reason I reopened this as an RFC was because I thought the more general questions should have been resolved as part of the discussion in Renato's support policy RFC and that therefore this would not necessarily be controversial to the point we couldn't resolve it as part of an RFC.

I meant "trouble". This proposal seems to be having a lot of trouble that GN should have had too. The biggest push back is about adding new build systems, not Bazel versus GN versus CMake.</div><div><br></div><div>There seems to be a conflict here about adding a secondary build system. The first could be always thought of as an exception, but the second looks very much like a pattern. The way I see it, from one side there's people worried about maintenance and proliferation of code that is not directly related to the LLVM project (like build systems, editor files, etc) and from the other side, there's people saying this has been happening for a long time.</div><div><br></div><div>I tried to solve that by starting the support policy, but not with the intent to validate the inclusion of GN/Bazel, just to help the discussion move to a consensus. I regret having written GN and Bazel by name, which only now I realise they could be used as leverage for one side of the discussion. It was not my intention, and I don't think we should ignore the issues just because GN has been included already, either.</div><div><br></div><div>My support for moving this to a document (not necessarily a proposal) is because for most of the original discussion around Bazel, throughout the discussion about the support policy and now the retake on Bazel's inclusions, Tom's points haven't been addressed completely. There seems to be more discussion around semantics, history and precedence than the actual technical details. I'm guilty of that, too, while trying to solve the conflict, and I apologise if the support policy has created more confusion than it solved.</div><div><br></div><div>I think laying out the issues in a document and discussing the technical aspects over it would make things easier, not harder. If the support policy needs to be amended to clarify that, so be it. We need to document what happens and what we want to happen, not fix some version of the past as a golden standard for the future.</div><div><br></div><div>But as I always say: whatever works. If you want to continue discussing in this thread, by all means, do go on.</div><div><br></div><div>cheers,</div><div>--renato</div></div></div>
