Any SMS loop example?

[zhongknocken]

I want to get the compiling result of SMS(Swing Modulo Scheduling), and I've compiled many programs using  the flag "-O3 -fmodulo-sched", but no loop is SMS scheduled. 
I'm now using gcc 4.0.0 20041212.
Can any one give me a program or a section of program which has loops that can be SMS scheduled? Thanks.
