LGTM aside from a minor nit in the testing.



================
Comment at: clang/lib/Sema/SemaDecl.cpp:4633-4637
 Sema::ParsedFreeStandingDeclSpec(Scope *S, AccessSpecifier AS, DeclSpec &DS,
                                  RecordDecl *&AnonRecord) {
-  return ParsedFreeStandingDeclSpec(S, AS, DS, MultiTemplateParamsArg(), false,
+  return ParsedFreeStandingDeclSpec(S, AS, DS, ParsedAttributesView::none(),
+                                    MultiTemplateParamsArg(), false,
                                     AnonRecord);

Thanks, I think this is more clear.


================
Comment at: clang/test/SemaCXX/attr-declspec-ignored.cpp:3-6
+// For this test, we want the contents of the namespaces to be indented, which
+// clang-format doesn't like. Also, clang-format reformats the long lines in a
+// way that's difficult to read.
+// clang-format off
----------------
We don't typically put clang-format markings into tests -- we don't require that tests be formatted, and it's a bug that precommit CI continues to fail because of it (https://github.com/llvm/llvm-project/issues/55982).

Feel free to remove this bit when landing.

Same here for this one.
