Artem, Justin,
I am running into a problem and I'm curious if I'm missing something or
if the support is simply missing.
Am I correct to assume the NVPTX backend does not deal with llvm.sin
and friends?
This is what I see, with some variations: https://godbolt.org/z/PxsEWs
If this is missing in the backend, is there a plan to get this working, I'd really like to have the intrinsics in the middle end rather than __nv_cos, not to mention that -ffast-math does emit intrinsics and crashes.
