From 9c2d52014c95cef4aa0cf7e39ed47a42643c9568 Mon Sep 17 00:00:00 2001 From: James Y Knight Date: Sat, 2 Jun 2018 02:44:10 +0000 Subject: Fix support for distinguishing archive members by timestamp on Darwin. On Darwin, the binary's symbol table points to debug info in object files -- potentially object files within a static library. Such a library may have multiple entries with the same name, distinguished only by timestamp. The code was already _attempting_ to handle this case (see the code in ObjectContainerBSDArchive::Archive::FindObject which disambiguates via timestamp). But, unfortunately, while the timestamp was taken into account on the _first_ lookup, the result was then cached in a map keyed only off of the path. Added the timestamp to the cache, and added a test case.
