@ilovepi Thanks for the review. I have a [personal branch](https://github.com/shiltian/llvm-project/tree/rfc-amdgpu-object-linking) that contains the full implementation. It might be slightly different from this PR but after this PR is merged, it will get updated accordingly. The part of indirect call handling is [here](https://github.com/shiltian/llvm-project/commit/3af71377673f1e77f68a46acbb09b247756b7e87#diff-4ff660fffc80e47b411b920cc6f70be1abc3e61f935ebad97e2ea0eb9b4177dbR182).
