COMPILER OPTIMIZATIONS FOR VECTOR INSTRUCTIONS |
| 摘要 |
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. |

1. An apparatus comprising:
at least one processor; a memory coupled to the at least one processor; a computer program residing in the memory, the computer program including a plurality of instructions that includes at least one vector instruction; and a compiler residing in the memory and executed by the at least one processor, the compiler including a vector instruction optimization mechanism that eliminates at least one vector element reverse operation from the computer program to enhance run-time performance of the computer program. |
