[PATCH] D45633: [XRay] Typed event logging intrinsic

[Keith via Phabricator via llvm-commits]

Add an LLVM intrinsic for type discriminated event logging with XRay.
Similar to the existing intrinsic for custom events, but also accepts
a type tag argument to allow plugins to be aware of different types
and semantically interpret logged events they know about without
choking on those they don't.

Relies on a symbol defined in compiler-rt patch https://reviews.llvm.org/D43668. I may wait
to submit before I can see demo everything working together including
a still to come clang patch.
