[PATCH] D25855: [lld] Optimize undefined weak symbols in LTO link.

[Evgeniy Stepanov via llvm-commits]

eugenis added inline comments.


================
Comment at: ELF/LTO.cpp:115
+    R.Undefined = B->isUndefined() &&
+                  (ObjSym.getFlags() & object::BasicSymbolRef::SF_Undefined);
+
----------------
I'm not sure this condition is correct. isUndefined() is true for non-prevailing definitions, which I try to avoid.
