Abstract
Systems and methods that add specifications to procedures in a garbage collector for indicating what each procedure does. Such annotations can be added in the source code, to indicate what the source code is to do when it runs—hence enabling an automatic verification of the garbage collector by a verification component. The specification can be presented as a logical formula that can be readily processed by a theorem prover, which is associated with the verification component. Such logical formulas can further employ regions to specify correctness of the garbage collector.
