I have a patch which improves this to:
<bb 2>:
D.1957_3 = (unsigned int) c_2(D);
D.1958_4 = D.1957_3 + 4294967248;
if (D.1958_4 <= 9)
goto <bb 3>;
else
goto <bb 4>;
<bb 3>:
D.1961_5 = (int) c_2(D);
D.1955_6 = D.1961_5 + -48;
<bb 4>:
# D.1955_1 = PHI <D.1955_6(3), 0(2)>
--- CUT ---
Note the addition is found via PRE on the RTL level though and then we convert
it to the an ifconversion but we should able to find that on TREE Level.
