[PATCH] D69418: [llvm-ar] Add output option for extract operation

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added a comment.

I think I'm leaning toward not adding this option at the moment for the compatibility reason. IIUC, llvm-ar was created because otherwise it would have been hard to create archives containing symbols from bitcode files, and except that feature, it was intended to be a drop-in replacement. If you land this patch and start depending on the feature, you can't easily go back to the other ar commands.

If llvm-ar is the most popular ar command, we can make a new option de-fact standard, but unfortunately that's not the case.

This option doesn't really depend on LLVM. If this feature is useful, this would be useful for other ar commands, and adding this option to a major ar command would maximizes the benefit. Maybe you should propose this option to GNU first?
