* Reland 4: [analyzer] NFC: Update test infrastructure to support multiple ↵Dominic Chen2017-03-031-2/+2
| | | | | | | | | | | | | | constraint managers Summary: Replace calls to %clang/%clang_cc1 with %clang_analyze_cc1 when invoking static analyzer, and perform runtime substitution to select the appropriate constraint manager, per D28952.

* [analyzer] Move the NewDeleteLeaks checker from CplusplusAlpha to Cplusplus ↵Anton Yartsev2014-10-211-1/+1
| | | | | | package. llvm-svn: 220289
* [analyzer] Shorten the malloc checker’s leak messageAnna Zaks2013-04-061-1/+1
| | | | | | As per Ted’s suggestion! llvm-svn: 178938
* [analyzer] Re-enable cplusplus.NewDelete (but not NewDeleteLeaks).Jordan Rose2013-04-051-2/+2
| | | | | | | | As mentioned in the previous commit message, the use-after-free and double-free warnings for 'delete' are worth enabling even while the leak warnings still have false positives. llvm-svn: 178891
* [analyzer] Split new/delete checker into use-after-free and leaks parts.Jordan Rose2013-04-051-2/+3
| | | | | | | | | | | | This splits the leak-checking part of alpha.cplusplus.NewDelete into a separate user-level checker, alpha.cplusplus.NewDeleteLeaks. All the difficult false positives we've seen with the new/delete checker have been spurious leak warnings; the use-after-free warnings and mismatched deallocator warnings, while rare, have always been valid. <rdar://problem/6194569> llvm-svn: 178890
* [analyzer] Reduced the unwanted correlations between checkers living inside ↵Anton Yartsev2013-04-041-0/+14
MallocChecker.cpp This fixes an issue pointed to by Jordan: if unix.Malloc and unix.MismatchedDeallocator are both on, then we end up still tracking leaks of memory allocated by new. Moved the guards right before emitting the bug reports to unify and simplify the logic of handling of multiple checkers. Now all the checkers perform their checks regardless of if they were enabled, or not, and it is decided just before the emitting of the report, if it should be emitted. (idea from Anna). Additional changes: improved test coverage for checker correlations; refactoring: BadDealloc -> MismatchedDealloc llvm-svn: 178814
