Summary: GNU ar supports the 'N' count modifier for the extract (x) and delete (d) operations. When an archive contains multiple members with the same name, this can be used to extract (or delete) them individually. For example: ``` $ llvm-ar t archive.a foo foo $ llvm-ar x archive.a -> Writes foo twice, overwriting it the second time :( :( $ llvm-ar xN 1 archive.a foo && mv foo foo.1 $ llvm-ar xN 2 archive.a foo && mv foo foo.2 -> Write foo twice, renaming it in between invocations to preserve all versions ``` Reviewers: ruiu, MaskRay Reviewed By: ruiu, MaskRay Subscribers: jdoerfert, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D59503 llvm-svn: 356466
