------- Comment #16 from jakub at gcc dot gnu dot org 2008-10-15 09:38 -------
After discussion with richi, I'd like to turn this into an enhancement request
for 4.5 to extend PRE/SCCVN to be able to optimize that:
# cn_43 = PHI <-1.0e+0(4), 1.0e+0(3)>
D.1267_44 = __builtin_pow (cn_43, 2.0e+0);
into a constant.
