Hello, I am trying to make the FP intrinsics (abs, sin, cos, sqrt) I've added work with the X86ISelPattern, but I'm having some difficulties understanding what needs to be done. I assume I have to add new nodetypes for the FP instructions to SelectionDAGNodes.h, and make nodes for these in SelectionDAGLowering::visitCall when I find the intrinsic... The part I don't quite

Hello, I didn't get any reply to my previous mail about adding floating point intrinsics to the X86 pattern instruction selector... And I could really need some help. Anyway, I think my confusion was caused partly by an already existing bug in the instruction selection for floating point compares. The case which emits code for the special case of comparing against constant 0.0 does not
