摘要： A method for preloading an application, a storage medium, and a terminal device are provided. The method includes the following. In response to a target application being detected to be closed, current state feature information of a terminal device is acquired. The current state feature information is compared with historical state feature information of the terminal device when the target application was closed. Target historical state feature information closest to the current state feature information is determined from within the historical state feature information according to a comparison result. The target application is preloaded, in response to determining that the target application is about to be launched again according to a historical usage regularity corresponding to the target historical state feature information.

摘要： A method, system, and/or computer program product optimizes execution of a computation. Multiple slots, each of which is a container for information, are defined. A coordinate tuple is defined for each of the multiple slots. The coordinate tuple describes a position of a slot along multiple dimensions in a slot space. The multiple dimensions describe roles for executing a software object, and each of the multiple dimensions has a same level of primacy such that no dimension has primacy over another dimension in the slot space. Multiple method slots are populated with software method objects that address different contexts and purposes as defined by coordinate tuples of the multiple method slots. Software method objects are retrieved from coordinate tuples in the slot space that match a defined context and purpose of a particular computation, which is propagated to a processor that is executing a particular software method object.

摘要： A method and an apparatus for an enhanced object model to allow concurrent execution for program code generated from dynamic programming languages, such as JavaScript, are described. An index structure may be introduced to an object model representing a dynamically typed object in addition to a type structure and a data payload storing property or field values of the object. Elements of the index structure may point at corresponding property values as an indirection for accessing the object.

摘要： A method for executing a machine code based on a dynamic language is disclosed. An execution guard is created as a value stored in a data structure. The value is representative of an expected condition or a set of conditions for a reusable portion of the machine code. The value representative of the expected condition(s) is compared to an actual value encountered later during execution of a portion of the machine code. The reusable machine code is executed if the actual value corresponds with the value representative of the expected condition(s). The execution guard is invalidated if any of the expected conditions changes.

摘要： Aspects include a computing devices, systems, and methods for hardware acceleration for inline caches in dynamic languages. An inline cache may be initialized for an instance of a dynamic software operation. A call of an initialized instance of the dynamic software operation may be executed by an inline cache hardware accelerator. The inline cache may be checked to determine that its data is current. When the data is current, the initialized instance of the dynamic software operation may be executed using the related inline cache data. When the data is not current, a new inline cache may be initialized for the instance of the dynamic software operation, including the not current data of a previously initialized instance of the dynamic software operation. The inline cache hardware accelerator may include an inline cache memory, a coprocessor, and/or a functional until one an inline cache pipeline connected to a processor pipeline.

摘要： Methods and systems are provided for implementing an inline cache that uses a data array to perform receiver class checks. The data array contains classes, targets, and counters. The invocation is forwarded to the appropriate target when the checked class matches. On the other hand, an inline cache miss expands the data array with the new receiver class. The inline cache stub counts the invocations for specific classes and stores the count into the data array. The optimizing compiler can generate better code using the call type frequency (e.g., sort checks, limit the number of checks to the most frequently used classes, etc.).

摘要翻译： 提供了方法和系统来实现使用数据数组执行接收器类检查的内联高速缓存。 数据数组包含类，目标和计数器。 当被检查的类匹配时，调用将转发到相应的目标。 另一方面，内联高速缓存未命中使用新的接收器类来扩展数据数组。 内联缓存存根对特定类的调用进行计数，并将计数存储到数据数组中。 优化编译器可以使用呼叫类型频率（例如，排序检查，将检查的数量限制到最常用的类别等）来生成更好的代码。

摘要： Methods and systems for testing a software program are provided. The methods include receiving a textual input for testing at least one static type used by the software program. The textual input of an embodiment is pre-linked to the at least one static type. The method includes creating a dynamic type based on the textual input in a dynamically typed language. The dynamic type is populated based on a predefined set of test vectors and is then passed on to the software program. The software program is executed using the dynamic type. Executing the software program by using the dynamic type invokes the at least one static type used by the software program.
