| Re: [cdt-dev] Change the order of visit according to the control flow of a program in AST. |
Note that Codan has code for building a control-flow graph, which it uses for the "no return in function ..." checker. The code is in org.eclipse.cdt.codan.internal.core.cfg.ControlFlowGraph and related classes. You may be able to reuse this code for your work. If you want to refactor things in such a way that the CFG is exposed as public API, I'd imagine we would be happy to accept patches that do that. Hope that helps, Nate ________________________________ > To: cdt-dev@xxxxxxxxxxx > From: mkucera@xxxxxxxxxx > Date: Tue, 22 Apr 2014 09:49:25 -0400 > Subject: Re: [cdt-dev] Change the order of visit according to the > control flow of a program in AST. > > > I believe you can subclass ASTVisitor and return PROCESS_SKIP in every > method you override.
