I noticed the same issues. I reverted parts of recent work by upstream FreeBSD in HardenedBSD's Cross-DSO CFI branch since that branch uses clang/llvm/lld 7.0.0.

unknown -z value: common-page-size=4096
I've switched to using devel/xtoolchain-llvm70 yesterday to build amd64 base starting with r338990, and among other issues, ld.lld70 refuses to link the kernel: Building /usr/local/obj/usr/local/src/amd64.amd64/sys/ARDMORE/kernel.full --- kernel.full --- linking kernel.full ld.lld: error: unknown -z value: common-page-size=4096 ld.lld: error: unknown -z value: ifunc-noplt *** [kernel.full] Error code 1 make[2]: stopped in /usr/local/obj/usr/local/src/amd64.amd64/sys/ARDMORE (ARDMORE is basically GENERIC-NODEBUG, not that it matters) The ifunc-noplt is a known issue, it obviously didn't make it upstream in time for LLVM 7.0.0, and thus we carry the feature downstream. The crux of this link error though, emaste@ quipped in PR 230604 that LLD prior to 7.0.0 accepted but ignored unknown options, but now at least 7.0.0 disallows unknown options entirely. Which brings up the -z common-page-size=4096: has LLD been ignoring this part the whole time, and is it of any meaningful use anymore (it seemed to mean something with bfd)? -- Charlie Li Can't think of a witty .sigline today… (This email address is for mailing list use only; replace local-part with vishwin for off-list communication) signature.asc Description: OpenPGP digital signature
