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.
