If a symbol with an undefined version in a DSO is not going to be exported into the dynamic symbol table then do not give an error message for the missing version. This can happen with the --exclude-libs option which implicitly gives all symbols in a static library the local version. This matches the behavior of ld.gold and is exploited by the Bionic dynamic linker on Arm. Differential Revision: https://reviews.llvm.org/D43126 llvm-svn: 332224
