Richard Plangger:

The first step of this project is to implement the first tests to ensure the correct instruction encoding.
Test cases comparing generated assembler to objdump (s390x eqivalent for test_rx86_64_auto_encoding) will be added to the source code. In addition it covers
the most common op codes such as Arithmetic, Branches, Load/Store from memory. All of them in various flavors (register-register, register-memory, memory-memory, ...).
The goal is to be able to correctly assemble simple functions (containing several operations in the body) and invoke them correctly.
