Yes, on a couple things if I remember too. Not super major though. Maybe that perf gap will be fixed in 10.0.1?

It's 10% worse for Rust so I would call that quite major, and master is even worse. The problem is LLVM does not track performance regressions at all which naturally makes things slower over time.

Well, some good news for Clang 10.0 on FF. Looks to be net positive perf improvement: https://bugzilla.mozilla.org/show_bu...id=1616692#c28 And if Rust gets bumped to 1.43, it should help perf even more. Here's hoping 78 gets built from Clang 10.0
