[PATCH] D93367: [ELF] --emit-relocs: fix a crash if .rela.dyn is an empty output section

[George Rimar via Phabricator via llvm-commits]

grimar added inline comments.


================
Comment at: lld/ELF/OutputSections.cpp:406
     // all InputSections in the OutputSection have the same dependency.
     if (auto *ex = dyn_cast<ARMExidxSyntheticSection>(first))
       link = ex->getLinkOrderDep()->getParent()->sectionIndex;
----------------
I wonder if the same crash can happen here with an empty `.ARM.exidx`?
