From 0dae776c6bf31e779c172753f6e2d6426eb42523 Mon Sep 17 00:00:00 2001 From: Emese Revfy Date: Tue, 24 May 2016 00:10:35 +0200 Subject: Add Cyclomatic complexity GCC plugin Add a very simple plugin to demonstrate the GCC plugin infrastructure. This GCC plugin computes the cyclomatic complexity of each function. The complexity M of a function's control flow graph is defined as: M = E - N + 2P where E = the number of edges N = the number of nodes P = the number of connected components (exit nodes).
