The failure should be caused by the line number changes in the `compiler-rt/test/ubsan/TestCases/TypeCheck/Function/function.cpp`, specifically in line:

  // CHECK-NEXT: function.cpp:[[@LINE-11]]: note: f() defined here

But the failure seems does not happen on PPC linux. I can not find a machine to reproduce this issue, could someone who can reproduce this failure help me to fix the case? @dyung ? Thank you!
