Hey All, On a system with clang 4.0.0 already installed with lld as ld, I get the following error compiling the latest HEAD of projects/clang400-import when WITH_LLD_IS_LD is set:
===> usr.bin/clang/lld (obj,all,install)

/scratch/fbsd/contrib/llvm/include/llvm/IR/Attributes.h:71:14: fatal error:
'llvm/IR/Attributes.gen' file not found
#include "llvm/IR/Attributes.gen"
Steps to reproduce:
1. Build and install a world with WITH_LLD_IS_LD set. The first build will
succeed.
2. After the new world is installd, verify that /usr/bin/ld is in fact lld by
running `ld -version`
3. If not, then set the symlink to /usr/bin/ld.lld
4. rm -rf the object directory (for me: /usr/obj/scratch/clang400)
5. do a new world build with WITH_LLD_IS_LD set. This will fail.
Thanks,
