[PATCH] D50475: ELF: Only add libcall symbols to the link if defined in bitcode.

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added inline comments.


================
Comment at: lld/ELF/Driver.cpp:1221
+
+  MemoryBufferRef MB;
+  if (auto *LO = dyn_cast<LazyObject>(Sym))
----------------
Is it too expensive or is there any problem if we simply call `Sym->fetch()` and see if the returned value is of BitcodeFile (and if so, add to the symbol table)?
