[LLVMdev] JIT compiled intrinsics calls is call to null pointer

I am trying to call an LLVM intrinsic (llvm.pow.f32), inserted with the
arg_types);auto result=ir_builder->CreateCall(function, args);
When I try to execute the code generated by the JIT compiler, I see that
the intrinsic is not compiled into a math coprocessor instruction, but in a
call to a null address:
002300B8 sub esp,8 002300BB movss xmm0,dword ptr
ds:[2300B0h] 002300C3 movss dword ptr [esp+4],xmm0 002300C9 movss
xmm0,dword ptr ds:[2300B4h] 002300D1 movss dword ptr
[esp],xmm0 002300D6 call 00000000 002300DB add esp,8
Is there anything special that I need to do in order to be able to call
intrinsics, either in general or when JITting? I am either doing something
wrong, or forgetting to do something, but I don't know what.
I am working with a Visual Studio compiled version on Windows (x86).
All hints will be appreciated, with kind regards,
