Function sgx_tstd::intrinsics::prefetch_read_data

pub unsafe extern "rust-intrinsic" fn prefetch_read_data<T>(
    data: *const T, 
    locality: i32
)

🔬 This is a nightly-only experimental API. (core_intrinsics)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

The prefetch intrinsic is a hint to the code generator to insert a prefetch instruction if supported; otherwise, it is a noop. Prefetches have no effect on the behavior of the program but can change its performance characteristics.

The locality argument must be a constant integer and is a temporal locality specifier ranging from (0) - no locality, to (3) - extremely local keep in cache
