nvcc & #define & x86 assembly

Seasons Greetings,

In the host code that launches the kernel, I would like put some x86 assembly and I do not want this to be a seperate function.
Unfortunately, this does not agree with the nvcc compiler driver.
I was wondering if nvcc defines a unique identifier which would enable me to hide this piece from it via #ifndef.

Edit: I found CUDACC (just a matter of locating the relevant manual ;-))
