The branch stable/13 has been updated by arichardson: URL: https://cgit.FreeBSD.org/src/commit/?id=a6898ea04e4dd6c1f4f60622df59f1cd97d288f0 commit a6898ea04e4dd6c1f4f60622df59f1cd97d288f0 Author: Alex Richardson <arichardson@FreeBSD.org> AuthorDate: 2021-04-15 15:27:52 +0000 Commit: Alex Richardson <arichardson@FreeBSD.org> CommitDate: 2021-04-22 09:44:53 +0000 lib/msun: Exclude ignored-pragmas from -Werror This avoids build failures due to the clang 12 warning: '#pragma FENV_ACCESS' is not supported on this target - ignored Clang 12 currently emits this warning for all non-x86 architectures. While this can result in incorrect code generation (e.g. on AArch64 some exceptions are not raised as expected), this is a pre-existing issue and we should not fail the build due to this warning.
