> As a preliminary clean-up, you might want to run update_llc_test_checks.py on this test file, so we can see the exact diffs in codegen.

I ran

  $python2 update_llc_test_checks.py --llc-binary <directory-of-llc>/llc llvm/test/CodeGen/X86/sibcall.ll

and it modified the sibcall.ll. I'm not familiar with with utility. I'm afraid I don't know how to use it properly and what is the meaning of the diff. I attached 2.patch. It is the changes this tool does to sibcall.ll. F5984860: 2.patch <https://reviews.llvm.org/F5984860>
