Abstract: A processing device includes a target processor instruction memory to store a plurality of target processor instructions that include a plurality of global memory access instructions. The processing device further includes a compiler to communicate with the target processor instruction memory, the compiler including: a global variable candidate detection module to identify a global memory access instruction within a set of code regions that use a set of global variable candidates to access a global memory, and a memory access optimization module to modify the global memory access instruction, wherein the modified global memory access instruction utilizes an unused base pointer register of a set of unused base pointer register candidates within the set of code regions, a global variable from the set of global variable candidates to be used as a base address, and an offset relative to the base address to access the global memory.

Abstract: A method and apparatus for optimizing computer program code. The method comprises identifying at least one set of candidate instructions within the computer program code, each candidate instruction comprising an instruction for writing a constant value to memory and the at least one set comprising a plurality of candidate instructions. The method further comprises computing an aggregate constant value for the at least one set of candidate instructions, and replacing the at least one set of candidate instructions with at least one instruction for writing the aggregate constant value to memory.
