@alexey-bataev, I have uploaded the clang PR that builds upon this, to emit ATTACH maps for array-sections/subscripts/array-shaping/stars for which the attachable base-pointer is a regular, non-member pointer decl, here: https://github.com/abhinavgaba/llvm-project/pull/1

Feel free to take a look and provide your feedback. I haven't marked it ready yet since it needs the runtime change from https://github.com/llvm/llvm-project/pull/149036. @adurang has agreed to add a commit to the runtime PR to enable order-respecting submitData in the plugins, after which it should be ready.
