I am able to read from a virtual file using clang::tooling::ToolInvocation::mapVirtualFile , however I dont know how to output to a virtual file or just to an std::string or char* , I tried passing -o out.S -ivfsoverlay out.S but it still writes to disk and as far as I can tell does not write to the memory I created.

I think you want to be sending questions about clang and clang-related tooling questions to the cfe-dev@ mailing list instead.
