Towards the next generation of XNU memory safety: kalloc_type

• clang

Doesn't seem -Wxnu-typed-allocators (which I forgot to mention above) is present in my version. Didn't test the others.

I also just realized that the latest tagged release of https://github.com/apple-oss-distributions/clang is 800.0.38, my clang is reporting 1400.0.29.102. Is Apple no longer releasing the source for their compilers?

• xnu

The article references a few compiler extensions: __builtin_xnu_type_signature, __builtin_xnu_type_summary, and the xnu_usage_semantics attribute.

I can see these references to these builtins in the latest xnu source[1], but not in upstream llvm[2], or Apple's forks of llvm[3] and clang[4].

It's been possible to build your own XNU[5] for a long time. Is that still possible now?
