followsFundamentalRule() returns true if "alloc" or "new" appear at the beginning of the string, not anywhere within it.

Implicit conversions from arrays can also be conversions to references (will add a test case shortly).

Issue warnings about owned objects returned from a method that does not match the established Cocoa naming conventions.

llvm-svn: 58108

Added method "getSelfRegion" to Store.  This method returns the region associated with the "this" or "self" object (C++ and Objective-C respectively).

The Decl of an array region can be VarDecl or FieldDecl. Handle this in RegionStoreManager::ArrayToPointer().

Disable warning about potential leaks of returned values until we test it a little more (lots of noise).

llvm-svn: 58021

Warn about potentially leaked objects that are returned from methods whose names do not follow the Cocoa Memory Management guidelines.

Enhance reference-count checker to correctly identify CG "release" functions.  This fixes <rdar://problem/6303488>.

When conjuring symbols for compound assignments, use the promoted type to determine if the symbolic value as a "loc::" or "nonloc::" value.

Handle [NSAutoreleasePool addObject:] (an alternative way to add objects to the current autorelease pool).

Added initial code for tracking stack of autorelease pools.

GRExprEngine::VisitCast() so that other parts of the analyzer can be ignorant.
When we cast "array of type T" to "pointer to T", we get the loc::MemRegionVal
corresponding to the array variable. This is sufficient for BasicStore, but not
for RegionStore. RegionStore should get the element region for the first array
element in the cast. So next comes to the revamping of transfer functions for
different store model.

Further improve path-sensitivity with divide-by-zero checking by assuming that a denominator cannot be zero even when the result of an '/' or '%' expression is unknown.

Used conjured symbols to recover path-sensitivity when the result of a compound assignment is UnknownVal().

Generalize VisitLValue: not only can CallExprs and ObjCMessageExprs return aggregate temporaries, so can many other expressions.

llvm-svn: 57761

Function calls and ObjC message expressions can be used in a lvalue context if they return a structure.  E.g  foo().x == 1.  We don't really support, however, such temporaries yet in the environment or the store.

llvm-svn: 57760

retain/release checker: Check if a tracked value escapes if we also try binding it to the store and the store doesn't support that binding (i.e., it cannot track it).  This has the nice feature that the checker will automatically get more powerful if we use a more powerful store model.

llvm-svn: 57755

Use "VisitLValue" when processing the base for "x.f" field accesses, and "Visit" when processing the base for "x->f" field accesses.
