Does anyone have an overview of which of these are actually useable on FreeBSD ELF binaries? Here's my impression from the audience (please correct me if I'm wrong):

* llvm-nm and llvm-objdump have been converted to Michael Spencer's object file library (http://www.llvm.org/devmtg/2010-11/Spencer-ObjectFiles.pdf) and should work on our binaries.

* lvm-ld only works on LLVM bitcode and either doesn't produce ELF binaries or uses binutils ld for this. Michael Spencer has plans for an llvm-ld that can replace binutils ld, but it's probably at least a year before something useful is ready. It would be great because it would bring LTO to FreeBSD.

* llvm-as is used by us already on i386/amd64(?)

* llvm-ar and llvm-ranlib are less useful as we have our own ar and ranlib by kaiw@


I don't know about the rest.

Thanks,
