  "message": "[InstCombine] Signed saturation patterns\n\nThis adds an instcombine matcher for code that attempts to perform signed\nsaturating arithmetic by casting to a higher type. Unsigned cases are already\nmatched, this adds extra matches for the more complex signed cases, which\ninvolves matching the min(max(add a b)) nodes with proper extends to ensure\nlegality.\n\nDifferential Revision: https://reviews.llvm.org/D68651\n\n\ngit-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@375505 91177308-0d34-0410-b5e6-96231b3b80d8\n",
