This solves the multiple defintiion issue https://github.com/llvm/llvm-project/issues/54269. I think the cause of the bug might be an oversight. We just forget to edit this when implementing partitions. And it should be a good fix. Reviewed By: iains Differential Revision: https://reviews.llvm.org/D121271
