optimistic.

TODO: actually implement the pessimistic version of the checker. Ex: it
needs to assume that any function that takes a pointer might free it.

The optimistic version relies on annotations to tell us which functions
can free the pointer.

compiler warning.)

using CFArrayCreate & family.

Specifically, CFArrayCreate's input should be:
'A C array of the pointer-sized values to be in the new array.'

Reenable DeadStoresChecker under --analyze, and move the IdempotentOperationsChecker to the 'experimental' category.  Fixes <rdar://problem/10146347>.

llvm-svn: 148533

Implement checker that looks for calls to mktemps and friends that have fewer than 6 Xs.  Implements <rdar://problem/6336672>.

llvm-svn: 148531

multiple checks are exposed as separate checkers, but CheckerManager only creates
one Checker object.

call and the operand of any sizeof expressions contained within
its argument(s).

The checker is responsible for defining attack surface and adding taint to symbols.

[analyzer] Move the knowledge of whether or not GC is enabled for the current analysis from CFRefCount to ExprEngine.

Remove TransferFuncs from ExprEngine and AnalysisConsumer.

Demote RetainReleaseChecker to a regular checker, and give it the name osx.cocoa.RetainCount (class name change coming shortly). Update tests accordingly.

[analyzer] rename all experimental checker packages to have 'experimental' be the common root package.

llvm-svn: 136835

[analyzer] Introduce MallocOverflowSecurityChecker, a simple flow-sensitive checker that may be useful for security auditing.  This checker is currently too noisy to be on by default.

KeychainAPI checker: only check the paths on which the allocator function returned noErr. (+ minor cleanup)

llvm-svn: 136694

Add a skeleton for the Keychain Services API Checker. Register it as OSX experimental for now. Note, the checker still does not handle tracking of escaped values, taking into account the return value of the allocator functions, nor the actual bug reporting.. 

llvm-svn: 136659

[analyzer] CStringChecker checks functions in the C standard library, not C++. Its external name is now unix.experimental.CString.

Add an Objective-C checker that checks that arguments passed to some variadic Objective-C methods are of Objective-C pointer types.

Ted or Argiris, I'd appreciate a review!

llvm-svn: 127572

Re-enable the IdempotentOperations checker for --analyze, and put it and the DeadStores checker into the "deadcode" group.

llvm-svn: 127531

This checker was created by Jim Goodnow II, and I migrated it to the
new Checker interface (recent changes by Argiris).

They cooperate in that NSErrorChecker listens for ImplicitNullDerefEvent events that
DereferenceChecker can dispatch.
ImplicitNullDerefEvent is when we dereferenced a location that may be null.
