[PATCH] D147815: [clang][deps] Print timing information

[Argyrios Kyrtzidis via Phabricator via cfe-commits]

akyrtzi added a comment.

Could you also add a `-terse` option, to avoid printing the full dependency 
info, if you mainly want to get the timing? Something like this:

  T.stopTimer();
  if (PrintTiming)
    llvm::errs() << llvm::format(
        "clang-scan-deps timing: %0.2fs wall, %0.2fs process\n",
        T.getTotalTime().getWallTime(), T.getTotalTime().getProcessTime());
  
  if (Terse) {
    if (Format == ScanningOutputFormat::Full ||
               Format == ScanningOutputFormat::FullTree ||
               Format == ScanningOutputFormat::FullIncludeTree) {
      llvm::errs() << "num modules: " << FD->getNumModules() << '\n';
    }
  
    return HadErrors;
  }

Where `getNumModules()` is

  size_t getNumModules() const {
    return Modules.size();
  }

So you still get some very high-level info but not the whole dump of info.
