Techniques for cloning programming code are disclosed. In an embodiment, the cloned code is in the form of functions in the C language. Further, in a method embodiment, a clone of a function is invoked, and information mapping the clone to the function is generated. At link time, if no function body of the clone is accessible by a linker, then the linker uses information mapping the clone to the function to satisfy a linker's requirement. At load time, if no function body of the clone is accessible by a loader, then the loader, based on the mapping information, allows selection of a body of the function. However, if the body function of the clone is accessible by the loader, then the loader allows selection of the body of the clone.

Disclosed are systems and methods for optimizing a program.

System and method for optimizing a program

The present disclosure relates to whole program analysis and, more particularly, short data optimization obtained through whole program analysis. In one embodiment, short data optimization is achieved by analyzing the program to estimate the size of existing short data and the size of any linkage tables, providing the size estimates to a compiler that is to compile the program, and compiling the program with the compiler in view of the size estimates such that a relatively large amount of data is allocated to a short data area.

An optical add-drop multiplexer comprises an optical switch () for selection of a desired wavelength channel to be extracted, a pre-processing channel assembly (), an optical reflector (), an optical extractor (), a post-processing channel assembly (), and an optical coupler () aligned with the post-processing channel assembly. The pre-processing channel assembly transmits a multiplexed signal stream containing a plurality of channels. The optical reflector directs light rays emitted from the pre-processing channel assembly into the optical extractor. The optical extractor comprises a narrow bandpass filter () that allows a desired channel to pass therethrough and reflects other unextracted channels. The desired channel can be dropped by switching to a corresponding output port of the optical switch. The optical reflector directs light rays reflected from the optical extractor to the post-processing channel assembly. The optical coupler combines the unextracted channels and an insertion channel.
