Symbols from C++ and Rust programs (or any other AoT-compiled programming language that uses the Itanium name mangling ABI) can be quite hard to map back to source code without demangling, especially in the presence of generics.

Describe the solution you'd like

It would be nice if binsider had an on-by-default option to demangle Itanium ABI symbols. The option could be toggled either via CLI or via a TUI shortcut. I've been using cpp_demangle to this end in crofiler as a pure-rust solution and it worked pretty well, although it does have a few edge cases where it does not perfectly match libiberty.

Describe alternatives you've considered

Demangling can also be done in many other ways, such as by binding to libiberty or calling the c++filt utility. Alternatively, you may also decide that demangling is not worth the code complexity cost. Or you may not want to provide an option to disable it for UI simplicity. I've seen a few demangling hiccups in tools I use (especially perf), which is why I think it's good to have a way to turn it off.

If you do want to have demangling, another UI design option besides an on/off TUI shortcut would be to have two columns in the symbol table, one with the mangled name and one with the non-mangled name, but I think this table is already a bit crowded for that...

Additional context

Prior art of common ELF-wrangling tools that can perfom demangling and do so by default, with an option to disable it, includes the perf profiler and the GDB debugger.
