The macro define __FP_FRAC_ADD_4 is below. It can fix the carry bug.
But still exist a problem that r

This bug exists in math emulation for powerpc.
The macro define are mainly used by multiplication.
When adding two unsigned operands ( r = x + y ),
the carry bit can be counted by whether r is less than x.
However, when adding three unsigned operands, this method does not work.
The original code
