This is because llvm-objdump doesn't support the -x option and doesn't accept joined single-character options. I've been meaning to submit a patch upstream for -x but haven't got around to it yet.

ZFS: I/O error - blocks larger than 16777216 are not supported
Hi all, I've been reported ZFS boot disable problem [1], and found that this issue occers form RAID configuration [2]. So I rebuit with RAID5 and re-installed 12.0-CURRENT (r333982). But failed to boot with: ZFS: i/o error - all block copies unavailable ZFS: can't read MOS of pool zroot gptzfsboot: failed to mount default pool zroot FreeBSD/x86 boot ZFS: I/O error - blocks larger than 16777216 are not supported ZFS: can't find dataset u Default: zroot/<0x0>: In this case, the reason is "blocks larger than 16777216 are not supported" and I guess this means datasets that have recordsize greater than 8GB is NOT supported by the FreeBSD boot loader(zpool-features(7)).

Thanks Shawn, right now I'm interested specifically in llvm-objdump, with the goal of sorting it out in advance of FreeBSD 12. I think it's a worthwhile endeavour to quantify the breakage from using all of the LLVM tools though, and if you're able to triage the issues and submit LLVM, FreeBSD, or upstream port issues as appropriate that would be much appreciated.

In preparation for Cross-DSO CFI support, HardenedBSD switched to llvm-ar, llvm-nm, and llvm-objdump on 12-CURRENT/arm64 with commit a3db6f9006499b55c2042faccd0ed6a6777b9d9f (22 Dec 2017). There are some issues with the ports tree, but I haven't quantified them, yet. All high-visibility applications (firefox, apache, nginx, openvpn, etc.) all work with a full llvm toolchain (again: llvm-ar, llvm-nm, and llvm-objdump). Some applications break during runtime and not build time. Certain pidgin plugins break, for example, at runtime due to a full llvm toolchain, but compile just fine.

[CFT] tinderbox/universe building clang once
https://people.freebsd.org/~bdrewery/patches/universe-one-clang.diff This will build clang once if any of the targets specified (or defaulted) require bootstrapping clang. It probably has some issues with LLD_BOOTSTRAP in some cases. It could be improved more in the future for reusing more of the tools built but I think this is good enough for now as it saves the majority of the time in the bootstrap phases on clang. This won't work for GCC unless it learns convenient -target support. Its needed --sysroot support was also broken until some recent work from John Baldwin but I'm not sure if that has been committed yet. Also FYI WITH_SYSTEM_LINKER support is now in to avoid building libclang for lld on archs that have LLD_BOOTSTRAP set. I'm putting this out for testing since tinderbox/universe take so long and I can't possibly test all workflows with it myself. -- Regards, Bryan Drewery signature.asc Description: OpenPGP digital signature

Tool Chain Migration: objdump users, please test llvm-objdump
Work is in progress to migrate fully to modern and permissively licensed components for the tool chain. This includes moving away from the three obsolete binutils components that are still in the base system (as, ld, objdump). objdump is a tool to report information about binary objects (such as headers, symbols, etc.), is not required as a build tool, and in any case many uses of objdump are better served by readelf. For FreeBSD 12 I intend to remove GNU objdump 2.17.50. PR 229046[1] is open to track tasks related to its removal, and users who need GNU objdump can install an up-to-date version from the ports tree or the binutils package. That said, llvm includes a somewhat equivalent llvm-objdump, and it is built by default in FreeBSD now. If llvm-objdump's command line option support and output format is "close enough" to GNU objdump for most users we may decide to install it as /usr/bin/objdump. Therefore, I would like to ask users of GNU objdump in FreeBSD to give llvm-objdump a try. Please let me know if it works for your uses, or describe deficiencies that you found.
