================
Comment at: llvm/test/ThinLTO/X86/devirt_after_filtering_unreachable.ll:11
+; RUN: llvm-dis -o - %t-main.bc.0 | FileCheck %s --check-prefix=ENABLESPLITFLAG
+; ENABLESPLITFLAG-DAG: [[BaseD0:\^[0-9]+]] = gv: (name: "_ZN4BaseD0Ev", {{.*}}, funcFlags: ({{.*}} mustBeUnreachable: 1
+
----------------
Since we don't ever use variable BaseD0, there isn't a need to capture a value there. In fact, you can ignore it completely and then change all 4 llvm-dis instances in this test to check the same pattern like:

; FLAG: gv: (name: "_ZN4BaseD0Ev", {{.*}}, funcFlags: ({{.*}} mustBeUnreachable: 1

(and no need for the -DAG handling since there is only one pattern being checked per llvm-dis invocation).
