No, something like the PS4 CPU features that don't get upstreamed because they might provide clues how to bipass PS 4 security.
There are some talks from Sony at LLVM meetings regarding those.
That PR from Apple has nothing to do with the bitcode reference I made.

Why do i want a PS4 specific cpu-drm feature in a generic Compiler?

I did not said it was a cpu-drm feature, rather optimizations that could reveal hints about it.
I don't know, maybe other AMD users would like to get them?
