I guess -fuse-ld=lld has to be specified in LDFLAGS, which does not seem to be in the failure case.
(In reply to Tee KOBAYASHI from comment #2) > I guess -fuse-ld=lld has to be specified in LDFLAGS, which does not seem to > be in the failure case. Just 2 lines above, in my emerge info I have LDFLAGS="-fuse-ld=lld -rtlib=compiler-rt"
(In reply to Anton Gubarkov from comment #3) > Just 2 lines above, in my emerge info I have > LDFLAGS="-fuse-ld=lld -rtlib=compiler-rt" Your emerge --info tells that "sys-libs/compiler-rt-12.0.1::gentoo was built with" that LDFLAGS. This does not necessarily mean that sys-libs/compiler-rt-13.0.0 (or even the rebuild of sys-libs/compiler-rt-12.0.1) is going to be built with the same LDFLAGS.

I had to revert this change. This flag breaks too many ebuilds and doesn't help here either.
I had the same problem here. The solution was to compile llvm with USE=gold. As far as I can tell, the meaning of USE=gold in llvm is completely different from USE=gold in all other ebuilds: Other ebuilds: "Use the gold linker" LLVM: Build the llvm plugin for the gnu linker (not only for the gold linker, but also for the bfd linker!) i.e. USE=gold is needed for llvm even if you don't use the gold linker!
The name is a historical one -- in the past, the plugin was used only by gold. I suppose I could change it but I'd rather do that for a future release -- I don't want to force people to rebuild all old versions for that. That said, I suppose we should default-enable it these days. I'm going to do that today.

I use LLD which doesn't need the "gold" USE flag enabled anywhere, and builds LTO objects just fine. The binutils gold linker isn't even installed as I'm using Clang+LLD system-wide. If you wish to build compiler-rt without `USE="gold" sys-devel/llvm` use the ld.lld linker instead.
