| // 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. |
