Greetings, I'm currently trying to build a large C++ project for MemorySanitizer with clang since g++ doesn't support MSan as far as I know. I currently try to build an instrumented libc++ so I don't get false positives for Msan. Now since some libs we use still link against libstdc++ I would like to ask if it is possible to build libstdc++ in the same way so it doesn't produce false positives with MSan and if there is a manual for it. Thanks for your help!
