[llvm-dev] Put ToolInvoker Output Into a String
Hello! So I am running clang programmatically using clang::tooling::ToolInvocation, however I dont want anything to touch the disk. 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. If this isn't the right place for this post or if I need to clarify something please let me know! Thank you - TFB -------------- next part -------------- An HTML attachment was scrubbed...
