Prefetches are issued for a memory access in the next iteration of a loop. |
This option enables or disables prefetches for a memory access in the next iteration of a loop. It is typically used in a pointer-chasing loop.
When -O1 or higher is specified on IA-64 architecture, prefetches are issued for a memory access in the next iteration of a loop. To disable these prefetches, specify -no-opt-prefetch-next-iteration (Linux) or /Qopt-prefetch-next-iteration- (Windows).
