Flush the cpu cache line by __builtin_clear_cache()
This crate can be used when you do benchmarks that are not dependent on the cpu cache.
Easy to use:
let a = vec![1, 2, 3, 4, 5, 6, 7, 8, 9];
clf::cache_line_flush_with_slice(&a);
or
let a = vec![1, 2, 3, 4, 5, 6, 7, 8, 9];
let begin_ptr = a.as_ptr();
let end_ptr = unsafe { begin_ptr.add(a.len()) };
clf::cache_line_flush_with_ptr(begin_ptr, end_ptr);
