// 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.
