- * When CONFIG_SUPPORT_DENORMAL_ARITHMETIC is defined, kernel prevents

- * 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
