================
Comment at: clang/lib/AST/ASTContext.cpp:11770-11778
+  if (!LangOpts.CUDA || LangOpts.CUDAIsDevice) {
+    assert(!ForAuxTarget && "Only CUDA/HIP host compilation supports mangling "
+                            "number for aux target");
     return Res;
+  }
 
   // CUDA/HIP host compilation encodes host and device mangling numbers
----------------
Nit: I'd rephrase it as :
```
if (LangOpts.CUDA && !LangOpts.CUDAIsDevice) {
    Res = ForAuxTarget ? Res >> 16 : Res & 0xFFFF; 
} else {
    assert(!ForAuxTarget && "Only CUDA/HIP host compilation supports mangling number for aux target");
}
return Res > 1 ? Res : 1;
```
