------- Comment #26 from jakub at gcc dot gnu dot org 2008-10-20 15:10 ------- On the #c11 testcase with -O2 -funsafe-math-optimizations I still see # cn_38 = PHI <-1.0e+0(4), 1.0e+0(11)> D.1262_39 = __builtin_pow (cn_38, 2.0e+0); D.1263_41 = 1.0e+0 - D.1262_39; D.1264_42 = __builtin_sqrt (D.1263_41); before and after PRE, so the recent pre change doesn't handle it.
