We currently do not touch a symbol's linkage in the case where a definition has a single copy. However, this code is effectively unnecessary: either the definition is not exported, in which case the internalize phase sets its linkage to internal, or it is exported, in which case we need to promote linkage to weak. Those two cases are already handled by existing code. I believe that the only real functional change here is in the case where we have a single definition which does not prevail (e.g. because the definition in a native object file prevails). In that case we now lower linkage to available_externally following the existing code path for that case. As a result we can remove the isExported function parameter from the thinLTOResolveWeakForLinkerInIndex function. Differential Revision: http://reviews.llvm.org/D21883 llvm-svn: 274784 |
