I'm working on the #pragma STDC FENV_ACCESS ON support, specifically the support for a strict version of the FP to unsigned int conversion. I've got a pass that runs and converts a new intrinsic into code that uses the FP to signed int conversion code similar to how SelectionDAG handles this now. Except that SelectionDAG will let the target handle it if the target says it will. How do I,
