Can you post a bit of the header diff before/after? I think I know what it 
looks like but just to be sure.



================
Comment at: clang/test/Sema/arm-neon-decl-after-stmt.c:3
+// RUN:  -Wdeclaration-after-statement -fsyntax-only -verify %s
+// REQUIRES: aarch64-registered-target || arm-registered-target
+// https://github.com/llvm/llvm-project/issues/54062
----------------
Does `armebv7` work when you only have aarch64?

It probably does just by virtue of aarch64 not knowing what v7 is and 
defaulting to v8 but double check what happens there.

If the emitter is used for both arm and aarch64 then testing one would be 
acceptable. Since you can't really do an if has arm do this else in a lit test 
like this.


================
Comment at: clang/utils/TableGen/NeonEmitter.cpp:1855
     emitOpeningBrace();
+    emitReturnVarDecl();
     emitShadowedArgs();
----------------
Comment the reason for doing the return var first
