I'm looking at the Legalize code and in 2.5 the above function is: void DAGTypeLegalizer::ExpandFloatRes_FADD(SDNode *N, SDValue &Lo, SDValue &Hi) { SDValue Call = LibCallify(GetFPLibCall(N->getValueType(0), RTLIB::ADD_F32, RTLIB::ADD_F64,

I don't understand the question. The new code is supposed to do exactly the same thing as the old code. Can you please be more explicit about what you think the problem is. > Is my

In the 2.4 code, it explicitly used 2 Operands to the MakeLibCall function, whereas in 2.5 it only uses 1 Operand. Other functions like pow, cos, sin, only use 1 Operand as I would expect since they are unary functions and div/mul uses two operands as expected. But after looking more closely at the code, I realized my Mistake in thinking that MakeLibCall was the same in both Cases but
