Perhaps the example plugin is unnecessary. I should use the cyclomatic complexity plugin because I already wrote about it in the sections "Usage" and "How to add a new GCC plugin" and they differ by only two lines. > For an example, I'd expect verbose comments. :) Imagine someone > reading it who knows very little about plugins or compiler internals. I think gcc has very good documentation about plugins, I reference them from gcc-plugins.txt, you can see it below. If you think it isn't enough tell me please what you would like to see as additional documentation. > > +1.
