So you're saying there is a use case to compile everything with clang and libstdc++? If that is actually something you need, and you don't need to be compatible to any name mangling, you just need the part of the patch in D12834 accepting abi tags and you should be fine (no dual ABI support ofc); no modifications to the name mangling (lib/AST/ItaniumMangle.cpp) are necessary for that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1488254 Title: clang++ no longer ABI-compatible with g++ To manage notifications about this bug go to: https://bugs.launchpad.net/llvm/+bug/1488254/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
