            Bug ID: 45491
           Summary: AArch64 emits invalid DBG_VALUE with only one operand
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org

This was found when stripping debug info from
llvm/test/CodeGen/AArch64/branch-target-enforcement.mir. It seems there's some
code that creates a `DBG_VALUE $lr` but only adds one operand instead of three.
This instruction should either be corrected or removed.

Fixing this will allow us to remove the workaround in:
