--- Comment #40 from [email protected] --- The multiple version scripts thing is a hack I use to get around the lack of support for symbol versioning in Rust[1], so I'm not sure it's worth adding a GNU ld feature just for that hack. My impression is that it replaces the version script because the default Rust one uses anonymous version nodes but the one for libpathrs uses named ones and usually linkers don't accept both (at least GNU ld doesn't). Again, this is not ideal -- ideally Rust would natively support this and there would just be one version script generated by rustc that combines my symbol version nodes and its own internal version script data. As I outlined above, I had a different hack to use GNU ld by creating a shell script wrapper for ld and collect2 to remove the problematic --version-script argument before passing things to ld, but there were other issues with that setup that felt a bit more fundamental (basically the symbol versions were completely broken, I don't remember the exact details so I would need to try to reproduce the issues again...). One of the other concerns flagged by the Rust folks was that symbol versioning and LTO have very poor interactions (even in LLD) and so it's possible that this is just a hard problem and LLD happens to work well-enough-ish but GNU ld happens to have a few different issues. I'm not sure. [1]: https://internals.rust-lang.org/t/support-symbol-versioning-with-export-name/23626 -- You are receiving this mail because: You are on the CC list for the bug.
