If the frm field contains an invalid rounding mode (101-111), attempting to execute any vector floating-point instruction, even those that do not depend on the rounding mode, will raise an illegal instruction exception. Call gen_set_rm() with DYN rounding mode to check and trigger illegal instruction exception if frm field contains invalid value at run-time for vector floating-point instructions.
