Partial in-lining handles copy and mismatch for small array sizes less than -XX:ArrayOperationPartialInlineSize bytes through JIT code rather than calling optimized stubs thereby saving costly call overhead.
Enabling partial in-lining optimization for AMD EPYC servers supporting AVX-512 feature. Following are the performance numbers on Turin at fixed frequency of 2.1GHz <img width="440" height="440" alt="image" src="https://github.com/user-attachments/assets/14b55ee3-b65c-4247-8739-67f1b94dceb4"; /> <img width="440" height="300" alt="image" src="https://github.com/user-attachments/assets/c00d6443-45a2-4277-961d-580ceea5da88"; /> Kindly review and share your feedback.
