It's not clear what you want to do. Are you looking to extend an
existing instruction set with additional custom instructions? Can you
explain why you want to do this?

For testing you don't need a custom toolchain - you can use inline
assembly with data statements to insert your custom instructions into a
program. Again it depends on what your eventual aim is here.
