Abstract: A loadable module design that can be implemented in hardware-limited platforms. In particular, according to various aspects, literal memory space (424) may be reserved to the loadable module on a processor (610) running in an absolute addressing mode, wherein the literal space (424) may be reserved in a valid address range accessible to one or more address-restricted instructions. At build time, a partial linking combining one or more object files (320, 322, 324) associated with the loadable module with operating system exported symbols (330) may be generated. Accordingly, at load time, literal space may be allocated to the loadable module from the reserved literal memory space (424) and text and data spaces may be allocated from unused memory (440) such that addresses associated with all internal functions and variables may be relocated according to start addresses associated with the literal, text, and data spaces.

Abstract: Systems and methods for performing dynamic code management, such as dynamic management of JavaScript tags in webpages or code segments in native applications, are disclosed. A user device loading a web or native application can access a factor, such as a user device-specific attribute or a piece of content of the webpage or native application being loaded. That factor can be applied to a rule that is evaluated (e.g., by the user device or a code server) to select one or more desired segments of code (e.g., JavaScript tags or native application code) to be executed by the user device from a pool of available code (e.g., pre-embedded code or dynamically injected code).

Abstract: Information representative of a graph-based program specification (110) has components, and directed links between ports of said components, defining a dependency between said components. A directed link exists between a port of a first component and a port of a second component. The first component specifies first-component execution code that when compiled enables execution of a first task. The second component specifies second-component execution code that when compiled enables execution of a second task. Compiling (120) the graph-based program specification includes grafting first control code to said first-component execution code, which changes a state of said second component to a pending state, an active state, or a suppressed state. Based on said state, said first control code causes at least one of: invoking said second component if said state changes from pending to active, or suppressing said second component if said state changes from pending to suppressed.

Abstract: Examples relate to providing distributed compilation of statically typed languages. In some examples, first order dependencies of a target module are identified, where each of the first order dependencies is associated with one of a number of dependent modules. Next, each first order dependency of is traversed to remove code references from source code of a corresponding module of the plurality of dependent modules, where each of the code references refers to a type defined in an indirect dependency of the target module, and compile the source code of the corresponding module to generate a module stub of a number of module stubs. At this stage, source code of the target module is compiled using the module stubs to generate a target program

Abstract: Methods for reducing memory loads for accessing global variables (globals) when creating executables for position independent (PI) code are disclosed. A first method includes compiling PI code (404), identifying globals (405), and determining whether globals are defined in the executable (407). If a global is not defined in the executable, a definition is created in the executable (409). A second method includes receiving a list of defined globals from instrumented PI code binary (601) and comparing the list with globals in the PI code (607). Memory loads are created for globals that are unlisted (609). A third method includes compiling PI code with special relocations for globals (801) and determining whether globals are defined in the executable (803). If the global is defined in the executable, the special relocation is replaced with a direct load of the global (805). If not, the special relocation is replaced with a two-instruction sequence that loads the global's address and then the global's value (805).

Abstract translation: 披露了在创建位置无关（PI）代码的可执行文件时减少用于访问全局变量（全局变量）的内存负载的方法。 第一种方法包括编译PI代码（404），识别全局变量（405），以及确定是否在可执行文件（407）中定义全局变量。 如果在可执行文件中未定义全局，则在可执行文件（409）中创建一个定义。 第二种方法包括从仪器化PI代码二进制（601）接收定义的全局变量的列表，并将该列表与PI代码中的全局变量（607）进行比较。 为不公开的全局变量创建内存加载（609）。 第三种方法包括用全局变量的特殊重定位（801）编译PI代码，并确定是否在可执行文件中定义全局变量（803）。 如果在可执行文件中定义了全局，那么特殊重定位将被替换为全局（805）的直接加载。 如果没有，则特殊重定位将替换为加载全局地址，然后加载全局值（805）的双指令序列。

Abstract: Systems and methods for improving the performance of mobile applications are disclosed. An exemplary method can include receiving a request for the application, where the request can include target device information. The method can also determine whether the application has been cached before. If the application has not been cached, the method can download the application as a bytecode and process the bytecode into the native code format, using an Ahead-of-time compiler. The method can also provide the application in the native code format to the target device over the network.
