--- Comment #13 from Li Pan <pan2.li at intel dot com> ---
overriding TARGET_CLASS_LIKELY_SPILLED_P hook may not be a fix as it will
generate sorts of spill for the below sample code.

vbool2_t test_vmfge_vf_f16m8_b2(vfloat16m8_t op1, float16_t op2, size_t vl) {
  return __riscv_vmfge_vf_f16m8_b2(op1, op2, vl);                              
                                                                               
                                                 }

need to re-think from the mode-switch side.
