[Andrew Ng via Phabricator via llvm-commits]

andrewng added inline comments.

Comment at: lld/ELF/ICF.cpp:228
     for (size_t i = begin; i < mid; ++i)
-      sections[i]->eqClass[next] = mid;
+      sections[i]->eqClass[next] = eqClass;

OK, no problem, although I have to admit this goes against my instinctive coding approach. But I guess that might be because most projects with which I've been involved, have put at least some importance towards the run-time performance of unoptimized debug builds. But if this is the "LLVM" way, then so be it.
