- * Return the current FP rounding mode
- *
- * Returns:
- * 0 - round to zero
- * 1 - round to nearest
- * 2 - round to postive infinity
- * 3 - round to negative infinity
- *
- * ok all we need to do is get the current FP rounding mode
- * index our map table and return the appropriate value.
- *
- * 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 explicitly 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.
