-        * However, the UDF and IEX trap enable bit in $fpcsr also lose
-        * their use.

-        * UDF_IEX_trap replaces the feature of UDF and IEX trap enable bit in
-        * $fpcsr to control the trap of underflow and inexact. The bit filed
-        * of UDF_IEX_trap is the same as $fpcsr, 10th bit is used to enable UDF
-        * exception trapping and 11th bit is used to enable IEX exception
-        * trapping.
-        *
-        * UDF_IEX_trap is only modified through fp_udfiex_crtl syscall.
-        * Therefore, UDF_IEX_trap needn't be saved and restored in each
-        * context switch.
