OutGetn

In the Outgen folder you will find:

• backend: it's the library and it should work as it is.

• frontend: the scripts using the backend and it is likely that you might need to modify some of the stuff.

Dependencies:

• CBMC

• gcov

• Z3 in python3 (packages z3 and z3-tools).

• Install pickle in python3

• Install deap in python3.

• Install pycparser, zss, deepcopy (copy), numpy, pandas,

• Maybe packages: six.moves, cffi, configparser, collections, parser, pdb, hashlib

How to use it:

There are 2 examples in the Frontend:

• OutGen.bash: OutGen algorithm

• XORSample.bash: XORSample algorithm

Examples of running:

export DFT_HOME=/path/to/DFT/folder export EURI_HOME=/path/to/DFT/folder

export DFT_HOME=/home/menendez/data/infotestsoft/OutGen export EURI_HOME=/home/menendez/data/infotestsoft/OutGen

bash program.bash input_c_file function_name directory_for_results number_of_inputs

bash OutGen.bash 9-A-17766602.c main examples/ 10

This will create a directory for the program 9-A-17766602.c and inside you will find these types of files:

• The preprocessed program *.pre.c.pre.c

• The instrumented version of the program that you pass to cbmc *.cbmc.c

• The ori is a version the equivalent version to the cbmc one but without the instrumentation: *.ori.c

• The inputs *.c.inputs (you can read them using pickle, see below)

• The constraints generated by CBMC (*z3) and their clean version for DFT (*clean.z3).

• The finalTest*.c is the executable of the test.

• The count.* gives you information about how many times you have reached the program point.

• The coverage* gives you information about coverage extracted with gcov. The related files of coverage are: gcov, gcda, gcno
