The branch main has been updated by dim: URL: https://cgit.FreeBSD.org/src/commit/?id=7b6f5ebef68194c09708abeb6426ca7602b6dab1 commit 7b6f5ebef68194c09708abeb6426ca7602b6dab1 Author: Dimitry Andric <dim@FreeBSD.org> AuthorDate: 2022-05-27 18:23:37 +0000 Commit: Dimitry Andric <dim@FreeBSD.org> CommitDate: 2022-05-28 13:46:38 +0000 Add several sanitizer ignore lists under /usr/lib/clang Some of the sanitizers from compiler-rt can use ignore lists, which are loosely modeled on valgrind's example. Upstream provides default lists for AddressSanitizer, CFI, and MemorySanitizer, so install these in the expected location, /usr/lib/clang/14.0.3/share.
