floop-block optimization taking time at compilation

[Abdul Wahid Memon]

Hello everyone

I have one simple question regarding floop-block optimization. I have
configured GCC 4.6.1 to use graphite optimizations. I tried some
optimization related to graphite and they are working fine, but
-floop-block is taking a lot of time during compilation time.

The program is a simple matrix multiplication program but it takes
around 300 to 400 seconds when compiling with -O3 -floop-block.

Any help will be very useful.

Regards

Abdul
