2012-08-06[analyzer] Add a checker to manage dynamic type propagation.Anna Zaks
Instead of sprinkling dynamic type info propagation throughout ExprEngine, the added checker would add the more precise type information on known APIs (Ex: ObjC alloc, new) and propagate the type info in other cases (ex: ObjC init method, casts (the second is not implemented yet)). Add handling of ObjC alloc, new and init to the checker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161357 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-03[analyzer] Track null/uninitialized C++ objects used in method calls.Jordan Rose
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161278 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-31[analyzer] Don't try to inline if there's no region for a message receiver.Jordan Rose
While usually we'd use a symbolic region rather than a straight-up Unknown, we can still generate unknowns via array subscripts with symbolic indexes. (And if this ever changes in the future, we still shouldn't crash.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161059 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-31[analyzer] Add a FIXME about devirtualization in ctors/dtors.Jordan Rose
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161058 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-31[analyzer] Let CallEvent decide what goes in an inital stack frame.Jordan Rose
This removes explicit checks for 'this' and 'self' from Store::enterStackFrame. It also removes getCXXThisRegion() as a virtual method on all CallEvents; it's now only implemented in the parts of the hierarchy where it is relevant. Finally, it removes the option to ask for the ParmVarDecls attached to the definition of an inlined function, saving a recomputation of the result of getRuntimeDefinition(). No visible functionality change! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161017 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-30[analyzer] Handle inlining of instance calls to super.Anna Zaks
Use self-init.m for testing. (It used to have a bunch of failing tests with dynamic inlining turned on.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161012 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-30[analyzer] Perform post-call checks for all inlined calls.Jordan Rose
Previously, we were only checking the origin expressions of inlined calls. Checkers using the generic postCall and older postObjCMessage callbacks were ignored. Now that we have CallEventManager, it is much easier to create a CallEvent generically when exiting an inlined function, which we can then use for post-call checks. No test case because we don't (yet) have any checkers that depend on this behavior (which is why it hadn't been fixed before now). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161005 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-30[analyzer] Very simple ObjC instance method inliningAnna Zaks
- Retrieves the type of the object/receiver from the state. - Binds self during stack setup. - Only explores the path on which the method is inlined (no bifurcation to explore the path on which the method is not inlined). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160991 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-30[analyzer] Only allow CallEvents to be created by CallEventManager.Jordan Rose
This ensures that it is valid to reference-count any CallEvents, and we won't accidentally try to reclaim a CallEvent that lives on the stack. It also hides an ugly switch statement for handling CallExprs! There should be no functionality change here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160986 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-26[analyzer] CallEvent is no longer a value object.Jordan Rose
After discussion, the type-based dispatch was decided to be bad for maintenance and made it very easy for subtle bugs to creep in. Instead, we'll just be very careful when we do have to allocate these on the heap. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160817 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-26[analyzer] Rename Calls.{h,cpp} to CallEvent.{h,cpp}. No functionality change.Jordan Rose
