Though it's possible to also fix that, so the main question might be: what is the name we want to display to the users? I guess it would be the best if this matched what is displayed by other tools ?


In this case, the output becomes the same as what has been chosen to be used by the common llvm demangler, which probably should be a good choice in general. In this case, a few more identifiers are added. Or I guess it can be discussed if that one should be changed (or add options to it, as @thakis said was possible).

In principle, but I normally don't run windows except in a very underpowered VM for testing things, and building there is no fun. I can spin up some more powerful VMs for some better testing though.

In this case, much of the functionality of these tests require having the MS DIA SDK available (which also implies building in MSVC/clang-cl mode, not mingw mode), for reading PDB files. Probably just another step to do, but I don't have it set up right now.
