------- Comment #4 from pinskia at gcc dot gnu dot org 2007-10-23 06:38 -------
So when out of SSA (TER) combines:
iftmp.1D.2042_25 = (derivedD.2000:: *) somemethodD.1996;
# SMT.36D.2106_36 = VDEF <SMT.36D.2106_34(D)> { SMT.36D.2106 }
iftmp.1_25 (0B);
It does not change the case where it knows it cannot throw now.
Looking into fixing out of SSA.
