* [analyzer][NFC] Move CheckerRegistry from the Core directory to FrontendKristof Umann2018-12-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ClangCheckerRegistry is a very non-obvious, poorly documented, weird concept. It derives from CheckerRegistry, and is placed in lib/StaticAnalyzer/Frontend, whereas it's base is located in lib/StaticAnalyzer/Core. It was, from what I can imagine, used to circumvent the problem that the registry functions of the checkers are located in the clangStaticAnalyzerCheckers library, but that library depends on clangStaticAnalyzerCore. However, clangStaticAnalyzerFrontend depends on both of those libraries. One can make the observation however, that CheckerRegistry has no place in Core, it isn't used there at all! The only place where it is used is Frontend, which is where it ultimately belongs. This move implies that since include/clang/StaticAnalyzer/Checkers/ClangCheckers.h only contained a single function: class CheckerRegistry; void registerBuiltinCheckers(CheckerRegistry &registry); it had to re purposed, as CheckerRegistry is no longer available to clangStaticAnalyzerCheckers. It was renamed to BuiltinCheckerRegistration.h, which actually describes it a lot better -- it does not contain the registration functions for checkers, but only those generated by the tblgen files.

* [analyzer] Add checker callback for beginning of function.Devin Coughlin2016-02-191-0/+6
| | | | | | | | | | Add a checker callback that is called when the analyzer starts analyzing a function either at the top level or when inlined. This will be used by a follow-on patch making the DeallocChecker path sensitive.

* [analyzer] Rename callback EndPath -> EndFunctionAnna Zaks2013-01-031-4/+4
| | | | | | | This better reflects when callback is called and what the checkers are relying on. (Both names meant the same pre-IPA.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@171432 91177308-0d34-0410-b5e6-96231b3b80d8

* [analyzer] Add debug.DumpCalls, which prints out any CallEvents it sees.Jordan Rose2012-07-101-2/+29
| | | | | | | | | | This is probably not so useful yet because it is not path-sensitive, though it does try to show inlining with indentation. This also adds a dump() method to CallEvent, which should be useful for debugging. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160030 91177308-0d34-0410-b5e6-96231b3b80d8
* [analyzer] Add a test that we are, in fact, doing a DFS on the ExplodedGraph.Jordan Rose2012-06-291-0/+57
Previously: ...the comment said DFS... ...the WorkList being instantiated said BFS... ...and the implementation was actually DFS... ...due to an unintentional change in 2010... ...and everything kept working anyway. This fixes our std::deque implementation of BFS, but switches back to a SmallVector-based implementation of DFS. We should probably still investigate the ramifications of DFS vs. BFS, especially for large functions (and especially when we hit our block path limit), since this might completely change our memory use. It can also mask some bugs and reveal others depending on when we halt analysis. But at least we will not have this kind of little mistake creep in again. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159397 91177308-0d34-0410-b5e6-96231b3b80d8
