That is why there is a backtrace. The assert is just asserting we can't create any new psedu registers as the register allocator has happened already. Basically the backend can't directly use copy_to_mode_reg/gen_reg_rtx after register allocation. How do you print where you can from when it is two layers deep? Also this is why there is a backtrace printed out to help out.
