ScalarEvolution class returns no valid loop exit count
Hi,
I have problems to estimate the loop exit count of a simple loop with the
ScalarEvolution class.
simple loop:
......
int a = 0;
for(int i; i < 10; ++i){
a = a + 1;
};
......
For the loop analyzation I use the ScalarEvolution class with the following
initialization:
......
void analysis(Function* func)
DominatorTree DT = DominatorTree();
DT.recalculate(*func);
