[LLVMdev] SoftenSetCCOpernads in LegalizeFloatTypes.cpp
While generating a libcall from floating point comparison, it always
assumes that the return type of those libcalls is i32.
Why not allow Targets to provide the correct return type?
EVT RetVT = MVT::i32; // <-- here
SDValue Ops[2] = { LHSInt, RHSInt };
NewLHS = MakeLibCall(LC1, RetVT, Ops, 2, false/*sign irrelevant*/, dl);
NewRHS = DAG.getConstant(0, RetVT);
CCCode =

Hi Sanjiv, I think a lot of the softening code assumes you are dealing
with float (32 bits). So it's not just a matter of changing the libcall
return type.

Yes, we are dealing with 32-bits only. But why the cmp libcalls have to
return a 32-bit value.
e.g. Our libcall for comparing two floats is
char _eq_f32 (float a, float b);
rather than
