[PATCH] D24377: [XRay] Implement the `llvm-xray account` subcommand

[Alexis Shaw via Phabricator via llvm-commits]

varno added a comment.

At line 182-195 the following code I think is simpler and results in the function performing the same work.

  if (Parent == ThreadStack.rend())
    return false;
  while (ThreadStack.back().FuncId != Record.FuncId) {
    const auto &Top = ThreadStack.back();
    recordLatency(Top.first, diff(Top.second, Record.TSC)):
    ThreadStack.pop_back();
  }
