FWIW, I think it would be nice for the IRBuider to have a kind of "strict FP" state, kind of like how we have a "fast math" state for adding fast-math flags, that will cause CreateFAdd and friends to produce the associated intrinsics, instead of the IR instructions, when strictness is enabled. -Hal > > On...

Hi Kevin, Thanks for reaching out about this, and thanks especially for offering to help. I've had some other priorities that have prevented me from making progress on this recently. As far as I know, there is no support at all in clang for handling the FENV_ACCESS pragma. I have a sample patch somewhere that I created to demonstrate how the front end would create the constrained intrinsics

I expect we'll need a &q...
