From Pigmeo - .NET/Mono/CLI (C#, VB.NET, C++/CLI, Nemerle...) for microcontrollers (PIC, dsPIC, AVR...)

CIL instruction not supported yet

When Pigmeo Compiler backend was parsing the CIL instructions contained in your application, it found an unknown instruction or an unknown combination.

The backend (the part of Pigmeo Compiler which converts CIL to assembly language) works by looking for combinations of CIL instructions to detect what your program is doing (it usually doesn't compile each instruction independently because it would be very inefficient), but an unknown instruction or series of instructions was found.

It usually means you are trying to use a feature not supported yet for your target architecture.
