[PATCH] D68789: [LoopNest]: Analysis to discover properties of a loop nest.

[Ettore Tiotto via Phabricator via llvm-commits]

etiotto added a comment.

Based on the feedback received during code review I have added a new public member function called 'getPerfectLoops' which can be used to retrieve a list of loops that are perfect with respect to each other.
For example, given the following loop nest containing 4 loops, 'getPerfectLoops'  would return {L1 LLVM Compiler Infrastracture <https://reviews.llvm.org/L1>,{L3,L4}}.

  for(i) // L1
    for(j) // L2
      <code>
      for(k) // L3
         for(l) // L4
