This change modified lld to in response the llvm change which moved to a more explicit symbol table in the object format. Based on patches by Nicholas Wilson: 1. https://reviews.llvm.org/D41955 2. https://reviews.llvm.org/D42585 The primary difference that we see in the test output is that for relocatable (-r) output we now have symbol table which replaces exports/imports and globals. See: https://github.com/WebAssembly/tool-conventions/issues/38 Differential Revision: https://reviews.llvm.org/D43264 llvm-svn: 325861
