* Replace OwningPtr with std::unique_ptr.Ahmed Charles2014-03-071-2/+2
| | | | | | This compiles cleanly with lldb/lld/clang-tools-extra/llvm. llvm-svn: 203279
* Expose the name of the checker producing each diagnostic message.Alexander Kornienko2014-02-111-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: In clang-tidy we'd like to know the name of the checker producing each diagnostic message. PathDiagnostic has BugType and Category fields, which are both arbitrary human-readable strings, but we need to know the exact name of the checker in the form that can be used in the CheckersControlList option to enable/disable the specific checker. This patch adds the CheckName field to the CheckerBase class, and sets it in the CheckerManager::registerChecker() method, which gets them from the CheckerRegistry. Checkers that implement multiple checks have to store the names of each check in the respective registerXXXChecker method.

* [analyzer] StackAddrEscapeChecker: strip qualifiers from temporary types.Jordan Rose2013-02-261-10/+11
| | | | | | | | | | | | With the new support for trivial copy constructors, we are not always consistent about whether a CXXTempObjectRegion gets reused or created from scratch, which affects whether qualifiers are preserved. However, we probably don't care anyway. This also switches to using the current PrintingPolicy for the type, which means C++ types don't get a spurious 'struct' prefix anymore. llvm-svn: 176068
* [analyzer] Rename callback EndPath -> EndFunctionAnna Zaks2013-01-031-3/+3
| | | | | | | This better reflects when callback is called and what the checkers are relying on. (Both names meant the same pre-IPA.) llvm-svn: 171432
* Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth2012-12-041-3/+3
| | | | | | | | | | | | | uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237

* [analyzer] C++ objects returned on the stack may be wrapped in ExprWithCleanups.Jordan Rose2012-08-291-1/+5
| | | | | | | | | | | | In C++, objects being returned on the stack are actually copy-constructed into the return value. That means that when a temporary is returned, it still has to be destroyed, i.e. the returned expression will be wrapped in an ExprWithCleanups node. Our "returning stack memory" checker needs to look through this node to see if we really are returning an object by value. PR13722 llvm-svn: 162817
* [analyzer] Inline constructors for any object with a trivial destructor.Jordan Rose2012-08-271-4/+11
| | | | | | | | | | | | This allows us to better reason about status objects, like Clang's own llvm::Optional (when its contents are trivially destructible), which are often intended to be passed around by value. We still don't inline constructors for temporaries in the general case. <rdar://problem/11986434> llvm-svn: 162681
* Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie2012-03-111-2/+2
| | | | | | | | | | (Lex to AST). The member variable is always "LangOpts" and the member function is always "getLangOpts". Reviewed by Chris Lattner llvm-svn: 152536

* Change references to 'const ProgramState *' to typedef 'ProgramStateRef'.Ted Kremenek2012-01-261-1/+1
| | | | | | | | At this point this is largely cosmetic, but it opens the door to replace ProgramStateRef with a smart pointer that more eagerly acts in the role of reclaiming unused ProgramState objects. llvm-svn: 149081
* [analyzer] Make the entries in 'Environment' context-sensitive by making ↵Ted Kremenek2012-01-061-1/+1
| | | | | | | | | | | | | | | | | | entries map from (Stmt*,LocationContext*) pairs to SVals instead of Stmt* to SVals. This is needed to support basic IPA via inlining. Without this, we cannot tell if a Stmt* binding is part of the current analysis scope (StackFrameContext) or part of a parent context. This change introduces an uglification of the use of getSVal(), and thus takes two steps forward and one step back. There are also potential performance implications of enlarging the Environment. Both can be addressed going forward by refactoring the APIs and optimizing the internal representation of Environment. This patch mainly introduces the functionality upon when we want to build upon (and clean up). llvm-svn: 147688

* Change operator<< for raw_ostream and NamedDecl to take a reference instead ↵Benjamin Kramer2011-10-141-1/+1

| | | | | | | | Also convert stack-addr-ps.cpp to use the analyzer instead of just Sema, now that it doesn't crash, and extract the stack-block test into another file since it errors, and that prevents the analyzer from running. llvm-svn: 138613
