[PATCH] D114009: [BPI] Look-up tables for non-loop branches. NFC.

[Yevgeny Rouban via Phabricator via llvm-commits]

yrouban added a comment.

instead of storing a bool value (swap the probability or not) it would be better to store final array of branch probabilities to set so it would not need to define probabilities every time and optionally swap them.

  auto Search = PointerTable.find(CI->getPredicate());
  if (Search == PointerTable.end())
    return false;
  setEdgeProbability(BB, Search->second);
  return true;
