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