  • Reconstruction of garbage collection information
    Patent number: 8489651
    Abstract: The reconstruction of garbage collection information corresponding to an application. Upon accessing a portion of compiler generated application code, a computing system generates computational results that identifies one or more program state storage locations that track live references or memory pointers that can be displaced during garbage collection. This may be performed for multiple application code portions (such as methods or functions of an application), and may be performed just before garbage collection. To generate the computational results, the application code portion may first be subjected to a liveness analysis to generate liveness analysis results in the form of one or more live program state storage locations in the application code portion. The computational results may then be generated using the liveness analysis results and type information from a type service to provide the set of storage locations referencing live memory objects.
