Intel Skylake/Kaby Lake processors: broken hyper-threading

No. Even though Skylake came out in 2015, Apple used an older CPU (Haswell) until the October 2016 MacBook Pros.

They used Skylake in late 2016 MBPs and Kaby in the 2017 models.

I'm on a Kaby

    Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz

I haven't seen any erratic crashes yet on code compiled by LLVM 8.1.0 on multiple projects (ROS, Qt5). I hope a microcode fix is pushed by Apple on behalf of Intel soon.

Are you from the future? Isn't LLVM currently at 4.0 and going for 5.0 soon?

macOS comes with Apple's build of Clang, which has different versioning from "proper" Clang.

That's going to be mess when LLVM proper catches up to those version numbers...

It prefixes the version with Apple LLVM so I assume it is versioned differently.
