The branch main has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=27f35b7dd418a82cf2f5bb618bd4bb7e81253f3a commit 27f35b7dd418a82cf2f5bb618bd4bb7e81253f3a Author: Mark Johnston <markj@FreeBSD.org> AuthorDate: 2023-04-04 15:21:51 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2023-04-04 18:08:16 +0000 libdtrace: Do not set SHF_ALLOC on SUNW_dof relocation sections The section will contain static relocations which do not need to be preserved after linking, and moreover these relocations may reference symbols that end up getting removed. Do not set SHF_ALLOC and instead let the linker decide what needs to be done.
