To run part 1
pip install -r requirements.txt
gcc -fPIC sample1.c
python -i tutorial1.py
Then run individual commands from the python interpreter such as
>>> safe_func_call(start + c_variables['test_function'])
To run part 2
gcc -rdynamic -fPIC -gdwarf-2 sample2.c -ldl
python -i tutorial2.py
Then try some commands
>>> find_section(mmap, process.getreg('rip'))
>>> run_c('printf("Hello world\n");')
>>> line_numbers()
>>> wait_for_count(2)
>>> save_state()
>>> wait_for_count(4)
>>> load_state()
>>> wait_for_count(4)
To run part 3
cd sample3
gcc -rdynamic -fPIC -gdwarf-2 sample3.c -ldl
gcc -shared -x c -o library.so -fPIC library.c
python -i tutorial3.py
Then try some commands
>>> reload_library()
>>> c_func_call("print_memory", starts["library.so"])
>>> c_lib_globals.extend(["int* memory", "int* program_counter",
... "void* toggle", "void* primitives"])
>>> run_c('((void (**)(void))primitives)[1]();')
>>> iter_()
>>> for _ in range(60):
... run_loop()
