Fangrui Song	40a9f2251b	[ELF] Replace unused output filenames with /dev/null in tests ... Post commit review at rLLD335992 llvm-svn: 336129	2018-07-02 17:48:23 +00:00
Rafael Espindola	3ddf2110d5	Bring back r307364. ... In addition this includes a change to prefer symbols with a default version @@ over unversioned symbols. Original commit message: [ELF] - Handle symbols with default version early. This fixes last testcase provided in PR28414. In short issue is next: when we had X@@Version symbol in object A, we did not resolve it to X early. Then when in another object B we had reference to undefined X, symbol X from archive was fetched. Since both archive and object A contains another symbol Z, duplicate symbol definition was triggered as a result. Correct behavior is to use X@@Version from object A instead and do not fetch any symbols from archive.
