AFLGO Source Code Analysis: Graph Construction and Distance Calc

AFLGO is a modification of AFL that perform directed fuzzing, for more information, please read the paper. In this article, I will analyze source code of AFLGO that constructs call graph and control flow graphs of given program to be fuzzed and uses these graphs to calculate distance from each block to target locations. Most of these works are implemented in and distance_calculator/main.cpp. The analysis is based on commit 154cf6f84951ee5099732e267d1e7c79c233f278, in case if author might change the code in the future.
