The comment above REGISTER_TRAIT_WITH_PROGRAMSTATE says that should not be used "for traits that must be accessible from more than one translation unit." I assume this is the case because the GDMIndex function that is generated is returning the address of a static variable, which would be different in different translation units. Also, addTransition always has arguments. > I've changed it to suggest CheckerContext::getState instead of addTransition in cases where there are no state updates and the updated state (as returned by addTransition) in cases where there are state updates. > ---- > I think the current flow does not make much sense anymore.

The order I was thinking of was: - Getting Started - Static Analyzer overview // Without the details of how states are represented - Idea for a checker // Also merge the current "AST Visitors" section into this one. - Checker Registration - Checker Skeleton - Program State Example // Not yet written. An example showing how the ExplodedGraph is constructed for a simple function, including both value constraints and custom program state, without describing the specific data structures used. - Program State Details // Builds on the previous section; describe the specifics of ExplodedGraph/ExplodedNode, components of ProgramState. - Representing Values - Custom Program States - Bug Reporting - Testing - Hints All of your other comments should be addressed; updated patch attached.
