Thanks for the patches, and sorry for not replying to your comment in Atari forum!

However, I've already added more generic mechanism for being able to autoload demangled symbols in Hatari:

So I'm a bit hesitant to add large amount of additional code for another mechanism to achieve the same.

As to the patch itself, I wonder why '.' "assembly prefix" handling in "demangle_it()" is necessary, is somebody really using mangled names in m68k assembly?

Currently the main problem with demangled symbols is that they cannot be given for debugger commands (e.g. as breakpoints), because debugger uses white space as argument separator, which does not work with C++ symbols (as they can contain almost any ASCII characters).

I think that should be fixed before adding any additional demangling support.

Handling that would require modifying the symbol names during TAB completion. Either by replacing all spaces temporarily with some other character (e.g. '@'), which would be ugly, or by auto-quoting the symbol names.

Latter would be a better, but it's more work because it also requires debugger parsing quoted content correctly, maybe also changing the '"' character (currently used to indicate given string needed evaluation before being given to debugger).
