In a leak's "name", indicate GC or non-GC bugs.

llvm-svn: 50679

generic and handles reference counts for NSObjects.

llvm-svn: 50674

the object was last used.  This can be confusing to users.

For example:

 // 'y' is leaked
x = foo(y);

instead:

x = foo(y);
  // 'y' is leaked

Added test case for NSMakeCollectable.

llvm-svn: 50653

highlight the most nested subexpression that appears most responsible (giving
the user better diagnostic feedback).

Updated test cases to illustrate this feature.

basic warnings (dead stores, null dereferences) on the first pass.

Correctly invalidate reference count state when passing objects by reference in message expressions we don't understand.

llvm-svn: 50541

Added temporary fix for Obj-C exception handling in the static analyzer: treat these as panic functions.

should catch this one easily.

lval passed as an argument.

Fix: Inverted diagnostic messages.

a CF memory leak occurred with GC enabled, etc.

Provide SizeOfAlignTypeExpr workaround in the static analyzer for taking the sizeof of a ObjCInterfaceType.

This removes the failure in null-deref-ps.c (test suite).

llvm-svn: 50449

EvalStore/EvalLoad to handle all loads/stores from symbolic memory, allowing us
to do checks for null dereferences, etc., at any arbitrary load/store (these
were missed checks before). This also resulted in some major cleanups, some
conceptual, and others just in the structure of the code.

This temporarily introduces a regression in the test suite (null-deref-ps.c)
before I add a new LVal type for structure fields.
