GCC-4.8.1 - loop optimizations

Hello,

I want to use some loop optimizations. 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.
