hello there... i am trying my hands on gcc optimisations options. i tried e.g. -finline-functions, -funroll-loops and the likes but none worked for me for ex. i tried -funroll-loops for code for (int i = 0; i < 3; ++i) a[i] = i; which should unroll like a[0] = 0 a[1] = 1 a[2] = 2 but it didn't seem to happen. please help me write good test case or suggest some. i am using gcc 4.1.2. tried 5.4.2 also on rhel5 Best Regards -- View this message in context: http://old.nabble.com/gcc-optimisation-problem-tp31332634p31332634.html Sent from the gcc - Help mailing list archive at Nabble.com.
