...; [ID=18] As I understand LLVM tries to lower the following call %28 = call ptx_device float @llvm.powi.f32(float 2.000000e+00, i32 %8) nounwind readonly to device intrinsic. The table llvm/IntrinsicsNVVM.td does not contain such intrinsic, however it should be builtin, according to cuda/include/math_functions.h Is my understanding correct, and we need simply add the corresponding definition to llvm/IntrinsicsNVVM.td ? How to do that, what are the rules? Thanks, - D.
