@XChy your change seems to be causing a test failure of `llvm/test/CodeGen/Generic/live-debug-label.ll` on several buildbots: - https://lab.llvm.org/buildbot/#/builders/183/builds/20800 - https://lab.llvm.org/buildbot/#/builders/188/builds/44495 - https://lab.llvm.org/buildbot/#/builders/245/builds/23249 - https://lab.llvm.org/buildbot/#/builders/280/builds/1949 - https://lab.llvm.org/buildbot/#/builders/119/builds/17315 Can you take a look...
