Some of the FPGA vendors used the old MIPS processor designs. It might be worth finding out if Xilinx did that, because there is a decent chance that the undocumented opcodes in the MIPS design would be the same in the Xilinx.

I thought FPGAs were just arrays of logic gates that you have to connect in order to establish a program. That would seem to me to mean that any hidden opcodes could only be found in the tools you use to program it.
