[PATCH] D120266: [clang][CodeGen] Avoid emitting ifuncs with undefined resolvers

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added inline comments.


================
Comment at: clang/lib/CodeGen/CodeGenModule.h:358
+  /// function declarations when we do not emit a definition for the resolver.
+  std::vector<llvm::GlobalIFunc *> MultiVersionIFuncs;
+
----------------
Optional: `SmallVector<X, 0>` typically compiles to less code.
