Hi Sergey,

Can I ask why would you need that?

Looks like there's specific knowledge about the types and instructions
codes in switches midway through that is not recognizing your new
pseudos.

One way to find them out is to grep for the instruction codes yours is
similar to, and then see if you need to add your pseudos
