  // This file tests how we construct two different flavors of the Clang CFG -
  // the CFG used by the Sema analysis-based warnings and the CFG used by the
  // static analyzer. The difference in the behavior is checked via FileCheck
  // prefixes (WARNINGS and ANALYZER respectively). When introducing new analyzer
  // flags, no new run lines should be added - just these flags would go to the
  // respective line depending on where is it turned on and where is it turned
  // off. Feel free to add tests that test only one of the CFG flavors if you're
  // not sure how the other flavor is supposed to work in your case.
