MaskRay added inline comments.


================
Comment at: llvm/tools/llvm-objdump/XCOFFDump.cpp:163
+  // Skip Shared object file.
+  if (O->isXCOFF()) {
+    if (dyn_cast<const XCOFFObjectFile>(O)->getFlags() & XCOFF::F_SHROBJ)
----------------
You can skip all `O->isXCOFF()` checks in this function thanks to the early return.


================
Comment at: llvm/tools/llvm-objdump/XCOFFDump.cpp:230
+
+    if (Flags & SymbolRef::SF_Protected) {
+      ExportSymbols.push_back(SymNameVisibilityTy(SymName, "protected"));
----------------
Just switch with the underlying binary format, instead of using a `SymbolRef` abstraction, then `SF_Protected` will not be needed.
