OK, I'm now confused. How does this dovetail with anonymous namespaces? Richard's suggestion was to avoid mangling the name at all and relying on pointers being different to distinguish between the anonymous namespaces in different translation units. If I understand correctly, the main thing we want is for libstdc++ to consider two typeinfos the same if they are the same type in the same file's anonymous namespace, but different if they have the same name but came from different files. I'm unclear how the symbols in the asm get turned into typeinfos, and thus how the transform needs to be done. Jerry
