Latest Patents
J Kevin O'Brien holds a patent for a "Method for improving the efficiency of arithmetic code generation." This invention provides a process within an optimizing compiler for transforming code to take advantage of update instructions available on some computer architectures. On architectures that implement autoindexing instructions or addressing modes, this process improves the code generated for looping constructs that manipulate arrays in memory. The process involves selecting memory referencing instructions inside loops for conversion to update forms, modifying those instructions to an update form available on a particular processor, and applying an offset compensation to other memory referencing instructions in the loop. This enables the program to address the appropriate locations while utilizing the available autoindexing instructions. The improved compiler and compiler process allow the compiler to convert program instructions that would otherwise convert to unsupported autoindexing instructions to those that are supported.
