[PATCH] D35944: [ELF] Disable relocation validation when targeting weak undefined symbols

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added inline comments.


================
Comment at: ELF/InputSection.cpp:731-733
+      bool UndefinedWeak = (Rel.Sym->isUndefined() || Rel.Sym->isLazy()) &&
+                           !Rel.Sym->isLocal() && Rel.Sym->symbol()->isWeak();
+      Target->relocateOne(BufLoc, Type, TargetVA, !UndefinedWeak);
----------------
I wonder if you really have to change this many places to handle weak undefined symbols. If you don't call `relocateOne` if `UndefinedWeak` is true, doesn't it work?
