The compiler does not support the PREFETCHW instruction for this microarchitecture. |
This option supports the PREFETCHW instruction in Intel® microarchitecture code name Broadwell and later.
When you specify this option, you must also specify option [q or Q]opt-prefetch.
The prefetch instruction is merely a hint and does not affect program behavior. If executed, this instruction moves data closer to the processor and invalidates any other cached copy in anticipation of the line being written to in the future.
