Abstract: A device-independent intermediate representation of a source code is generated and stored, e.g., in a memory or other storage mechanism. The stored intermediate representation of the source code is used to generate a device-specific machine code corresponding to the source code. The stored intermediate representation may be updated, e.g., periodically, for example by obtaining an updated version of the source code and compiling the updated source code to generate an updated intermediate representation. The stored intermediate representation may be based on source code received from a device that is synchronized with which a compiling device that generates the device-specific machine code. In some cases, the stored intermediate representation may be used to generate for each of a plurality of devices a corresponding device-specific machine code.

Abstract translation: 生成并存储源代码的与设备无关的中间表示，例如存储器或其他存储机制。 所存储的源代码的中间表示被用于生成对应于该源代码的设备专用机器代码。 所存储的中间表示可以例如周期性地被更新，例如通过获得源代码的更新版本并且编译更新的源代码以生成更新的中间表示。 存储的中间表示可以基于从与产生设备专用机器代码的编译设备同步的设备接收的源代码。 在一些情况下，所存储的中间表示可以用于为多个设备中的每一个生成对应的设备专用机器码。
