Hi Stefan,

I personally appreciate the fact that you are prodding and probing LLVM, finding deficiencies, and I think it is great that you are willing to contribute your insights to the community.  I would personally also really appreciate it if you would take guidance from the community and log bugs (it isn’t that hard!) so we can properly track this.  Not doing so is becoming borderline spam on this mailing list given the volume of posts.  I think your work here is very valuable and so I’d really like to capture it to allow it to make a lasting impact on LLVM.

That said, regardless of what your decision on that is (I can understand if it isn’t worth your time), your tone above is not productive or constructive, and the LLVM community expects cordial communication with a baseline of a respectful tone.  I request that you be considerate of the fact that you are speaking on a public LLVM community list, and therefore are expected to remain in line with the community expectations.

Thanks.  Please feel free to contact me offline if you have questions or concerns,
