Hi Everyone,
TL;DR: See https://reviews.llvm.org/D26386 for initial documentation for XRay.
I've spent some time documenting how to use XRay from stuff that's already available in LLVM, Clang, and compiler-rt.
This is the first time I'm contributing to documentation for LLVM, and it'd be greatly appreciated if someone good at word-smithing would have a look.
Cheers
-- Dean
