> ArraySupport.vectorizedMismatch is a leaf level comparison routine which gets called by various public Java APIs (Arrays.equals, Arrays.mismatch). Hotspot C2 compiler intrinsifies vectorizedMismatch routine and emits a call to a stub routine which uses vector instruction to compare the inputs.
>
> For small compare operation whose size fits in one vector register i.e. < 32 bytes or <= 64 bytes, this patch employ partial in-lining technique to emit the fast path code at the call site which does vector comparison under the influence of a predicate register/mask computed as a function of comparison length.
>
> If the length of comparison is greater than the vector register size then the slow path comprising of stub call is emitted.
>
> This prevents the call overhead associated with stub call which is significant compared to actual comparison operation for small sized comparisons.
>
> Partial in-lining works under the influence of a run time flag -XX:UsePartialInlineSize=32/64 (default 32 bytes).
