hi, Have a great day In GCC does optimization levels O2 and O3 use profile information by default without specifying -fprofile options explicitly? Because O3 uses flags like -fipa-cp-clone which actually require profile information. If so , where are the data files related to profile information stored for reference? thank you -- P.Ezhil, Asst Prof, L.N GOVERNMENT COLLEGE, PONNERI - 601204
