The branch main has been updated by mmel: URL: https://cgit.FreeBSD.org/src/commit/?id=e59b6e48f4c8bbfee43a1bc6d9fd47691d3bd603 commit e59b6e48f4c8bbfee43a1bc6d9fd47691d3bd603 Author: Michal Meloun <mmel@FreeBSD.org> AuthorDate: 2023-08-13 05:51:56 +0000 Commit: Michal Meloun <mmel@FreeBSD.org> CommitDate: 2023-08-13 07:35:48 +0000 gdtoa: Regenerate configuration headers for 32-bit arm. These configuration headers were only guessed, but unfortunately not exactly correctly. Therefore, re-generate them on real HW. Generated on CA15, verified on CA9, CA7(with VFP lite) and on 32-bit ARMv9.
