[PATCH] D32395: [clang-tidy] modernize-use-emplace: remove unnecessary make_pair calls

[Jakub Kuderski via Phabricator via cfe-commits]

kuhar created this revision.
kuhar added a project: clang-tools-extra.

When there is a push_back with a call to make_pair, turn it into emplace_back and remove the unnecessary make_pair call.

Eg.

  std::vector<std::pair<int, int>> v;
  v.push_back(std::make_pair(1, 2)); // --> v.emplace_back(1, 2);

make_pair doesn't get removed when explicit template parameters are provided, because of potential problems with type conversions.
