Sounds good. Please do the `hasAttr`/`CollectBTFTagAnnotations` refactor in a separate preliminary commit (cleaning up any existing callers that have the null check like that), then commit this in two parts, llvm first, then clang.



================
Comment at: clang/lib/CodeGen/CGDebugInfo.cpp:1503-1504
+    llvm::DINodeArray Annotations = nullptr;
+    if (field->hasAttr<BTFTagAttr>())
+      Annotations = CollectBTFTagAnnotations(field);
+
----------------
could the `hasAttr` test be sunk into the `CollectBTFTagAnnotations` function? (so it's not repeated at all the callers)
