				silvasUnsubmitted Not Done Reply Inline Actions Can you use CHECK-DAG directive to move these next to the place where the `BW_` capture occurs? That would improve locality and clarify what is being checked. (same in the other files) silvas:* Can you use CHECK-DAG directive to move these next to the place where the `BW_*` capture occurs?
