This artifact collects the examples used in the paper and provides them
as a test suite. Each example is a separate program that can be used in a
number of ways. The program’s text is used in the paper. No results are
generated.

Each program takes a single input that controls which path through
the program is taken and gives a single output that records which branches
were taken. This allows them to be used for back-to-back testing with
compilers, interpreters, source-to-source translation, or dynamic analysis
tools. If the input/output relation changes, then transformation is buggy
and unable to handle that kind of loop.

They also have assertions that hold true only for valid paths through
the program, making them ideal for testing with static analysis tools. If
an assertion fails, it indicates a bug in the static analysis tool.
To demonstrate how these can be used, we provide a setup to test
CBMC.
