hi all, 
 
well, i have set up proper command line parameters for 
for C-Shootout tests to get reasonable running time 
for benchmarking. I have compared "gcc -O3" and  
"llvmgcc -Wl,-native-cbe" 
 
here goes output (which shows that llvm is already  
better for test with intensive function calls):
