I have build GCC-4.8.1 using gmp 5.1.3, mpfr 3.1.2, mpc 1.0.1, cloog 0.18.0 and isl 0.11.1. I tried optimization flags -floop-interchange and -floop-block. I don't find any changes in the optimized code. Are graphite loop transforms implemented in GCC-4.8.1. Should I configure and build GCC in a different way. I am new using GCC. Please help. Thanks and Regards, Ashwath.
