Abstract: A computer-implemented method for compilation of applications can include receiving a set of software instructions and traversing the set of software instructions based on a control-flow order of the set of software instructions. The traversing can include identifying a first allocation instruction in the set of software instructions, the first allocation instruction being configured to allocate a first amount of memory for a first object and identifying a second allocation instruction in the set of software instructions, the second allocation instruction being configured to allocate a second amount of memory for a second object. The method can include determining that the first allocation instruction dominates the second allocation instruction and, in response to the determining, combining the first allocation instruction and the second allocation instruction into a folded allocation instruction that allocates the first amount of memory and the second amount of memory in a single memory allocation operation.

Abstract: Systems and methods for configuring browser policy settings on client computing devices are provided. In some aspects, a method includes receiving login credentials from a client computing device. The client computing device includes a browser. The method also includes transmitting browser policy data associated with the login credentials to the client computing device. The browser policy data identifies browser policy settings to be installed on the browser. The browser policy settings identified by the browser policy data include four or more of: compliance settings, behavioral settings, browser/software applications, permission to access one or more websites, restrictions on accessing one or more websites, read permission in a remote document storage unit accessible via the browser, or write permission in a remote document storage unit accessible via the browser.

Abstract: Systems and methods for compiling source code are provided. In some aspects, a method includes receiving one or more code stubs configured to be inline cached at one or more call sites of a native code generated by a baseline compiler from a source code. Each of the one or more code stubs is based on an intermediate representation between the source code and the native code. The method also includes translating the source code into the intermediate representation, inlining the one or more code stubs into the translated source code, and optimizing, by an optimizing compiler, at least one of the translated source code and the inlined one or more code stubs.

Abstract translation: 提供了编译源代码的系统和方法。 在一些方面，一种方法包括：接收一个或多个代码存根，其被配置为在基准编译器从源代码生成的本地代码的一个或多个调用位置处进行内联缓存。 一个或多个代码存根中的每一个基于源代码和本地代码之间的中间表示。 该方法还包括将源代码转换为中间表示，将一个或多个代码存根内联到经翻译的源代码中，以及通过优化编译器优化至少一个经翻译的源代码和内联的一个或多个代码存根 。

Abstract: A system and method is disclosed for sharing type information between object maps. When an object data structure is modified in a dynamic programming environment to change an initial number of object properties a child object map for the modified object data structure is generated based on a parent object map for the unmodified object data structure, and a descriptor array associated with the base object map is shared with the child object map. The descriptor array is dynamically altered according to the modified object data structure, and access to the descriptor array is limited from the parent object map in accordance with the initial number of object properties of the unmodified object data structure.

Abstract translation: 公开了用于在对象映射之间共享类型信息的系统和方法。 当在动态编程环境中修改对象数据结构以改变对象属性的初始数量时，基于用于未修改的对象数据结构的父对象映射生成修改的对象数据结构的子对象映射，以及相关联的描述符数组 与基对象映射与子对象映射共享。 描述符数组根据修改后的对象数据结构进行动态改变，根据未修改对象数据结构的对象属性的初始数量，对父对象映射进行限制。
