[LLVMdev] getSmallConstantTripCount problem

[Bo Wu]

In my pass, I add LoopInfo as a required pass. Then I'd like to print the
constant loop trip count of each loop if it has one. However, every time I
call loop->
getSmallConstantTripCount(), it returns 0, even for a very simple loop:
for(i=0; i<3; ++i) {;}  What's the possible cause of this problem?

regards,
Bo
