nds32: Avoid IEX status being incorrectly modified In order for kernel to capture each denormalized output, the UDF trapping enable bit is always raised in $fpcsr. Because underflow case will issue not an underflow exception but also an inexact exception, it causes that the IEX, IEX cumulative exception, flag in $fpcsr to be raised in each denormalized output handling. To make the emulation transparent to the user, the emulator needs to clear the IEX flag in $fpcsr if the result is a denormalized number. However, if the IEX flag has been raised before this floating point emulation, this cleanup may be incorrect. To avoid the IEX flags in $fpcsr be raised in each denormalized output handling, the IEX trap shall be always enabled.
