/*
 * Return the current FP rounding mode
 *
 * ok all we need to do is return the current FP rounding mode
 *
 * HOWEVER:
 * The ARM FPA codes the rounding mode into the actual FP instructions
 * so there is no such thing as a global rounding mode.
 * The default is round to nearest if rounding is not explictly specified.
 * FP instructions generated by GCC will not explicitly specify a rounding
 * mode.
 *
 * So the best we can do it to return the rounding mode FP instructions
 * use if rounding is not specified which is round to nearest.
 *
 * This could change in the future with new floating point emulators or
 * soft float FP libraries.
