Jonas Jensen	88a251c05a	C++: Delete library-tests/qlcfg/cfg.ql ... This test was intended to catch regressions in the CFG, but it looks like it's just catching insignificant extractor changes. The test has started failing after some recent extractor changes, but I have no way to pinpoint the failure and understand whether it's a problem or not, so I think it's better to delete this test. The remaining tests check whether the QL-based CFG generates the same graph as the extractor-based CFG. Furthermore, the `successor-tests` check that the extractor-based CFG works as intended.	2019-01-11 08:24:07 +01:00
Jonas Jensen	9146b8e32e	C++: Add example of conditional destruction ... The QL CFG and extractor CFG are the same, so the test passes. Neither of them model that `ref` may or may not be destructed.	2019-01-09 15:02:25 +01:00
Jonas Jensen	26f32f0d6d	C++: Initial version of CFG.qll ... This implements calculation of the control-flow graph in QL. The new code is not enabled yet as we'll need more extractor changes first. The `SyntheticDestructorCalls.qll` file is a temporary solution that can be removed when the extractor produces this information directly.	2019-01-04 13:34:36 +01:00
