This intrinsic inserts an instruction prefetch, for example
PLI, into the instruction stream generated by the compiler. It enables you to signal to the memory system from your C or C++ program that an instruction load from an address is likely in the near future.
denotes any number of pointer or integer arguments specifying addresses of instructions to prefetch.
If the target architecture does not support instruction prefetching, the compiler generates
PLI instruction nor a
NOP instruction, but
ignores the intrinsic.
