Demangle support

[kassane]

Although the goal is to integrate into zig toolchain, assuming there is some internal difference.

Can you tell me if the standalone zld supports c++ demangle if used in place of the default linker?

Already in the zig language I have been thinking about maybe trying the proposed solution for the rust demangle mold linker being a zig library by doing some zFFI tests.

• Demangle Rust symbols rui314/mold#371 (comment)

For I believe it would be a more natural alternative than simply using @"_Zfoo".

e.g.:

• Support generation of Zig bindings mozilla/cbindgen#732 (comment)

Hi @kassane! No, there is no C++ demangle support yet. I'd be happy to guide you through the codebase, and help you integrate it if you were thinking of implementing it, and would very much welcome it :-)

Thanks for the feedback.

While still working on converting the solution to zig, partly translate-c cannot help me completely. I have to redo some points manually before this step can be completed.

WIP: https://github.com/kassane/rsDemangle-zig/blob/main/src/demangle.zig

After the code transition I will try to insert it into my zld-fork (which already has in test sample rust and cpp code).

Looks great @kassane! I'll be more than happy to accept your PR for inclusion in the main zld repo when you think it's ready!

In Rizin we use our own library for demangling, in pure C. Maybe it could be helpful for you, at the very least to test against: https://github.com/rizinorg/rz-libdemangle
