Cause: 1. `implicit_def` inside bundle does not count for define of reg in machineinst verifier 2. Including `implicit_def` will cause relative reg not define, result in `Bad machine code: Using an undefined physical register` in the machineinst verifier Fixes https://github.com/llvm/llvm-project/issues/139102 --------- Co-authored-by: Matt Arsenault <Matthew.Arsenault@amd.com>
