Abstract: A scheduling method performed by a computing device that includes a plurality of processors, a type of at least one instruction set of instruction sets supported by at least one of the plurality of processors is different from a type of an instruction set of instruction sets supported by another processor, where the scheduling method includes obtaining a type of an instruction set of an application, selecting a target processor from the plurality of processors, where the type of the instruction set of the application is a subset of types of a plurality of instruction sets of instruction sets supported by the target processor, and allocating the application to the target processor for execution.

Abstract: Provided is a code translation method. The method includes: obtaining first code, where the first code is written based on a platform-dependent language of a source platform, then determining at least one translation rule that matches the first code, where the translation rule is used to directly translate code of one platform into code of another platform, and then translating the first code by using the translation rule, to obtain second code applicable to a target platform. This method implements automatic cross-platform translation of code by using the translation rule, and improves translation efficiency and translation accuracy.

Abstract: A code processing method includes: obtaining first code, where the first code is code that is obtained through compilation and that is applicable to a source platform; then relocating addresses of variables associated with functions in the first code, to obtain logical addresses of the variables; and then performing decompilation based on the logical addresses of the variables and the first code, to obtain second code applicable to a target platform.

Abstract: This application discloses code processing methods, apparatuses, and storage media. An example method includes: obtaining a first code in low-level language and applicable to a source platform; decompiling the obtained first code to obtain an intermediate representation (IR); and then compiling the IR into a second code in low-level language and applicable to a first target platform, where the source platform and the target platform have different instruction sets.

Abstract: In a cross-platform code conversion method, a conversion device obtains first source code that is configured to run on a first platform. The conversion device performs syntactic analysis on the first source code to generate a syntax tree corresponding to the first source code, and identifies a to-be-converted syntax block in the syntax tree according to a syntax rule provided by a rule library. The conversion device converts the to-be-converted syntax block according to a conversion rule provided by the rule library to obtain a converted syntax block. The conversion device then generates, based on the obtained converted syntax block, second source code for running on a second platform.

Abstract: An improved anti-malware protection system protects computers against exploits in a scripting language that may be run in a browser. The system comprises a recorder that records scripting language execution events, a trace generator that transforms the recorded scripting language execution events into an execution trace, and a security engine that scans the execution trace and advises a security software about exploits found in the execution trace. By hooking the recorder into a runtime application programming interface for the scripting language, the improved protection system can detect exploits dynamically without the need for a browser-dependent plugin. An optional plugin can be included to perform file-based analysis of the script in addition to the runtime analysis of the script. The system can provide an application programming interface that can be used by multiple security software programs from multiple vendors to create an enhanced security software product.

Abstract: Technologies are presented that allow application events to be recorded and replayed in a reliable and deterministic manner. A computing system may include a memory and a processor communicatively coupled with the memory. The processor may execute application logic of an application, record events associated with the application based on invocation of functions associated with the events, and store the recorded events in the memory for future playback. Recorded events may include, for example, user interactions, timing events, network downloads, callbacks, web worker tasks, etc. The recording of the events may include recording top-level functions of each event according to their order, and recording associated data including function parameters and/or return values. The recorded events may be replayed in order using the recorded associated data while suppressing non-recorded events.

Abstract: Embodiments of a system and method for enhanced graphics rendering performance in a hybrid computer system are generally described herein. In some embodiments, a graphical element in a frame, application, or web page, which is to be presented to a user via a web browser, is rendered either by a first processor or a second processor based on indications of whether the first or the second processor is equipped or configured to provide faster rendering. A rendering engine may utilize either processor based on historical or anticipated rendering performance, and may dynamically switch between the hardware decoder and general purpose processor to achieve rendering time performance improvement. Switches between processors may be limited to a fixed number switches or switching frequency.

Abstract: A method to eliminate redundant store and load instruction pairs in the optimization of a stack-based language comprises determining data dependencies within a sequence of instructions, identifying a store-load instruction pair within the sequence of instructions, identifying one or more stack location insensitive sequences between the store-load instruction pair that enclose one or more of the data dependencies, reordering the one or more stack location insensitive sequences based on the data dependencies to place the two instructions of the store-load instruction pair immediately adjacent to each other, and removing the store-load instruction pair.
