      x4 is the thread pointer register and would be modified by the kernel. With this respect, we shall not modify or change its value. In the riscv-port repo, we have no other modifications for the x4 register so I would recommend removing the x4 saving logic in java frames. Verified along with other patches under full tiers jdk/hotspot on boards.
