----------------
I'm guessing this is the expected result that you want to check?
It needs to be actually checked..

Look at other files in that directory, e.g. `test/Analysis/Delinearization/constant_functions_multi_dim.ll`
You are missing `; RUN: opt -delinearize -analyze < %s | FileCheck %s` as the first line, and the actual check line.
And check if `llvm/utils/update_test_checks.py` can help generate the actual check lines.
