Abstract
An optimizing compiler includes a vector optimization mechanism that optimizes vector instructions by eliminating one or more vector element reverse operations. The compiler can generate code that includes multiple vector element reverse operations that are inserted by the compiler to account for a mismatch between the endian bias of the instruction and the endian preference indicated by the programmer or programming environment. The compiler then analyzes the code and reduces the number of vector element reverse operations to improve the run-time performance of the code.
