Some updated post fact from the BoF at the EuroLLVM conference:
* Constrained intrinsics: Steve, Matt and Andrew to continue working the newest iteration of this feature, working towards an initial implementation that we can add to for multiple architecture usage. Steve, if a thread is currently active, can you chime in here about it.
* FTZ: Extending FMF for FTZ, need clarity on whether code might be optimized to FTZ or is optimized to FTZ as the feature spec.
See thread: [RFC] Making space for a flush-to-zero flag in FastMathFlags
* FMF caller/callee and inlining: We are looking into this internally here at Apple at least initially for consistency of results for shaders. I may start a thread on this if others are interested.
* Complex numbers and Vector Masking: We need an owner for this, would someone like to start a thread on this?
