        <pre>If we run opt like this:

opt -disable-basicaa -licm -loop-unroll -O1 -unroll-threshold=0 -o
bbi-32266_2.opt.bc bbi-32266_2.ll

and check the size of the output bbi-32266_2.opt.bc I get

-rw-r--r-- 1 uabelho eusers 203308 sep 16 13:09 bbi-32266_2.opt.bc

Then, if I just add a "minsize" attribute to function main in the input
and run opt the same way, I instead get this output:

-rw-r--r-- 1 uabelho eusers 3177960 sep 16 13:12 ./bbi-32266_2.opt.bc

So, adding "minsize" makes the size of the program increase around 15 times.</pre>
