Where are you getting this clang from? When I test using clang 11 from the LLVM apt repos right now it seems fine, and clang 11 doesn't seem to have been released yet so I'm guessing this is some kind of snapshot. > Quick look at the log suggests that these are caused by HDRTEST, whatever > that is. AFAICT that's something that's supposed to be checking for include guards and not doing anything fancy... I can't think what could cause this on a per-function basis. --fdj2RfSjLxBAspz7 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl60JCAACgkQJNaLcl1U h9Dvowf+I+U4pcQnYnmNHOmPe/w6MMdKl+eVz7n/WXcEjLWLGmtIHyYdD58eWx6d J75DPJTAAaud5LeaVaB77OaY23Sx8n/q8RQ5FoUGc3ekQJVYkrYi+362HmI/UNcz vo/hQ6YklaZEpM3dRsVlbxEJU5VRCMMaD1zzRpEOHuA2y0fGyeGXD7w2h8UWfJZQ yN6LqBQoYVw524WoZ0kwn5nc4SvPbjiZg0Rky3ZChfwa5TyCyElLl7gaD1N3IEd+ bHiMVVRSktwkjD9zw2GY3CQVy+KHwFQIGAbHF0T5KrXC5cu48YXVARB3ThFW1++4 ZM56LEnOcEN1sUcsB8rAUuVjLswjoQ== =rwDI -----END PGP SIGNATURE----- --fdj2RfSjLxBAspz7-- --===============8841076602939921040== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel --===============8841076602939921040==--
