[PATCH] D47675: [test-suite][RFC] Using Google Benchmark Library on Harris Kernel

[Michael Kruse via Phabricator via llvm-commits]

Meinersbur added a comment.

Using Polly's `-debug-only=polly-scops` output showed that the kernel is in fact not optimized:

  Invalidate SCoP because of reason 0
  
  NOTE: Run time checks for %for.cond11.preheader---%for.cond.cleanup532 could not be created as the number of parameters involved is too high. The SCoP will be dismissed.
  Use:
          --polly-rtc-max-parameters=X
  to adjust the maximal number of parameters but be advised that the compile time might increase exponentially.
  
  Bailing-out because could not build alias checks

Using `-polly-rtc-max-parameters=999` does not help. I remember that Polly prints that message whenever it cannot build the alias checks, even for other reasons than stated.
