Appl. No.:

12/813404

Inventors:

Lin Xu - Seattle WA, US
Weiping Hu - Sammamish WA, US
Yongkang Zhu - Bothell WA, US

Assignee:

MICROSOFT CORPORATION - Redmond WA

International Classification:

G06F 9/45

US Classification:

717151

Abstract:

Embodiments are directed to tracking variable location information in optimized code and efficiently collecting and storing reaching definition information. A computer system receives a portion of source code at a compiler, where the compiler is configured to compile and optimize the source code for execution. The computer system tags selected variables in the source code with a tag, where the tag is configured to provide location information for the variable. The computer system optimizes the received portion of source code including changing at least one of the tagged variables. The computer system also tracks the tagged variables as the variables are changed by the compiler during code optimization and persists the variable location information, so that the persisted variable location information is available to other compiler components.

Brent Eugene Rector - Redmond WA, US
Jackson Michael Davis - Bothell WA, US
Saji Abraham - Kirkland WA, US
Lin Xu - Bellevue WA, US

Assignee:

MICROSOFT CORPORATION - Redmond WA

International Classification:

G06F 9/44

US Classification:

717127

Abstract:

The claimed subject matter provides for systems and/or methods for debugging a computer-executable file. The computer-executable file may be executing in a first runtime environment and located in a first process. The file may further comprise on object having a proxy in that first runtime environment. One method embodiment comprises the steps of debugging said computer-executable file; detecting a proxy for an object called by said file; decoding said proxy to obtain physical information regarding said object; returning said physical object information; and transforming said physical object information into logical object information. In addition, one embodiment of a system is provided that comprising a debugger, said debugger debugging client code; a proxy decoder, said proxy decoder providing information to said debugger about the object pointed by said proxy; and an abstraction transformation, said abstraction transformation transforming physical expressions of a proxy into higher level logical expressions.

Inventors:

LIN XU - Carlisle MA, US

International Classification:

G06F 3/06
G06F 17/30

Abstract:

A system and method for dynamic data management may receive a request from an operating system (OS) of a computer for device parameters to be provided to the OS; provide virtual Mass Storage Device (MSD) parameters, wherein the virtual MSD parameters cause the OS to determine that the device has an OS-supported file system, and wherein the device does not have an OS-supported file system; receive from the OS, based on the virtual MSD parameters, data retrieval requests, wherein each data retrieval request comprises at least a request for information regarding files of data and corresponding data management information; map data stored in the data storage medium to the data retrieval requests; and provide a virtual data map to the OS based on the mapping; wherein the virtual data map enables the OS to retrieve and manage the information regarding the files of data.
