I have been modifying LLVM a project of mine, and have encountered issues with overloading an intrinsic function.
I have defined two types, abit (which is mapped, in Intrinsics.td, to i128) and qbit (accordingly mapped to i16). I would like my intrinsic function, CNOT(x,y), to accept either an abit or a qbit for each argument, so I overload with iAny and llvm_anyint_ty, as seemed to be the method for other intrinsics:
def int_CNOT: Intrinsic<, [llvm_anyint_ty, llvm_anyint_ty],,[“llvm.CNOT”]>;
My llvm/clang directory builds successfully, but I get an error on getType from clang, which I believe is rooted in my llvm code. My question is simply, are there any additional steps to overloading an intrinsic? I stand to believe there is more to be done than what I did in the one line above, but I cannot find where to do this.
For what its worth, I get this error in generating the initial IR through clang:
