Our code assumes all input sections in an output SHF_LINK_ORDER section has SHF_LINK_ORDER flag. We do not check that and that can cause a crash. That happens because we call std::stable_sort(Sections.begin(), Sections.end(), compareByFilePosition);, where compareByFilePosition predicate does not expect to see null when calls getLinkOrderDep. The same might happen when sections refer to non-regular sections. Test cases demonstrate the issues, patch fixes them. Differential revision: https://reviews.llvm.org/D44193 llvm-svn: 327006
