Use this updated interface when invalidating arguments passed by reference; the type of symbol is of the object passed by reference, not the reference itself.

Changed casing of many bug names.  The convention will be to have bug names (mostly) lower cased, and categories use some capitalization.

llvm-svn: 56385

- Change definition of store::Region and store::Binding (once again) to make
  them real classes that just wrap pointers. This makes them more strictly
  typed, and allows specific implementations of Regions/Bindings to just
  subclass them.
- minor renamings to RegionExtent and its subclasses
- added a bunch of doxygen comments

StoreManager: (static analyzer)
- added 'iterBindings', an iteration method for iterating over the bindings of a
  store. It that takes a callback object (acting like a poor man's closure).
- added 'getRVal' version for store::Binding. Will potentially phase the other
  versions of GetRVal in StoreManager out.
- reimplemented 'getBindings' to be non-virtual and to use 'iterBindings'

BasicStoreManager: (static analyzer)
- implemented 'iterBindings' for BasicStoreManager

llvm-svn: 55536

Migrated CFRefCount.cpp to use getBindings and BindingsAsString instead of
making assumptions about the Store (removed dependence on GRState::vb_iterator).

directly, but instead have GRStateManager manage it.

llvm-svn: 54862

- Remove ConstNotEq from GRState/GRStateManager (!= tracking uses GDM instead).
- GRStateManager now can book-keep "contexts" (e.g., factory objects) for uses
  with data elements stored into the GDM.
- Refactor pretty-printing of states to use GRState::Printer objects
  exclusively. This removed a huge amount of pretty-printing logic from
  GRExprEngine.

CFRefCount
- Simplified some API calls based on refinements to the GDM api.

of using CheckerState).

Removed CheckerState from GRState.

Added class GRStateRef which wraps GRState* and GRStateManager*. This is handy
for generating new states with a single handle.

Added member template set/get functions to GRStateRef/GRState/GRStateManager for
accessing the Generic Data Map.

llvm-svn: 54788

Updated checker state printer interface to allow transfer functions to return an arbitrary number of GRState::Printers.

llvm-svn: 54762

Rename ValueStateManager -> GRStateManager.

Add variadic addInstMethSummary() and refactored addPanicSummary() to use this method. (code reduction).
Misc. cleanups.

llvm-svn: 54694

 - Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h
 - Moved Sema::getCurMethodDecl() out of line (dependent on
   ObjCMethodDecl via dyn_cast).

isRetain() and isRelease() now only returns true if "Retain"/"Release" appears in the suffix of a function's name.

llvm-svn: 53617

current store implementation is now encapsulated by BasicStore.

These changes prompted some long due constification of ValueState. Much of the
diffs in this patch include adding "const" qualifiers.

passed-by-reference to a function. This allows us to build up constraints for
their new values and restore some lost path-sensitivity. This addresses a few
false positives since in Adium.

llvm-svn: 53125

Refactored some of the BugReporter interface so that data such as the ASTContext&, PathDiagnosticClient*, can be provided by an external source.
Split BugReporter into BugReporter and GRBugReporter so checkers not based on GRExprEngine can still use the BugReporter mechanism.

now this does the same thing as "MayEscape", but more functionality will go in
here shortly.

llvm-svn: 52904

Tracked objects now have their type information tracked with them.

Enhanced summaries for ObjC methods to include the type information of the receiver.

Used the enhanced summaries to support the idiom that NSWindow owns itself (it sends a release message to itself upon close).

Added some comments.

Did some cleanups with the checker logic using operator overloading (reduced redundant code which I was concerned about being the source of bugs).

Added ObjCSummaryCache, a new summary cache object to cache summaries for Objective-C methods.  Instead of mapping from Selectors -> Summaries, we will now map from (ObjCInterfaceDecl*,Selectors) -> Summaries.  This will allow more nuanced summary generation.  This patch just swaps in the new data structure; the rest of the code works as before by allowing the ObjCInterfaceDecl* to be null.

llvm-svn: 52653

Rename summary methods for "instance methods" to "class methods" (the names got screwed up).  No functionality change.

llvm-svn: 52650

The CF retain/release checker now assumes that allocations do not fail.  Eventually we will add a flag to the driver to enable allocation failures (documented as a FIXME).
