10# Some limited unit tests that check the generated code.
11# Note that the generated C++ code is also functionally tested in the
12# file 'test_compiled_cpp_code.py'.
13# That test generates C++ code from an example register set, compiles it and performs some
14# run-time assertions in a C program.
15# That test is considered more meaningful and exhaustive than a unit test would be.
