I wasn't aware of this, I know Rui the COFF owner in lld puts in a lot of effort into lld for chrome link times.
Maybe he just uses it as a benchmark then :D
I actually caused a regression in migrating def code from lld to llvm with symbol mangling because we were missing a test case for this specific type of mangling and within hours it ended up on a chromium bug tracker and was fixed also within hours by Reid another googler on LLVM.

Yes, I should have been a bit more clear. You can link with lld (we have bots running that do this; we're even setting up a bot that enables ThinLTO). But lld support for emitting PDB files isn't quite there yet.
