Compiler-specific Features
Restrictions
If the target architecture does not support data prefetching, this intrinsic has no effect.
This intrinsic only takes effect in ARMv7 architectures and above that provide
Multiprocessing Extensions. That is, when the predefined macro
__TARGET_FEATURE_MULTIPROCESSING is defined.
Example
void foo(int *bar)
{
__pldw(bar);
}

4.7.21 __pli
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.
Syntax
void __pli(...)
Where:
... denotes any number of pointer or integer arguments specifying addresses
of instructions to prefetch.
Restrictions
If the target architecture does not support instruction prefetching, this intrinsic has no
effect.
