Description
Warning: [200-945] Loop should have only have
one exit point.
This message reports that the code is violating loop merging optimization rules.
Explanation
Loop merging optimization requires the loops to not have multiple exit conditions, as shown in the following code:
void example_label(int A[50], int B[50]) {
int i=0;
#pragma HLS loop_merge force
do{
B[i] = A[i] + 5;
if(B[i]==A[i]*B[i])
{
break;
}
else if (B[i] == A[i]+B[i])
{
break;
}
i++;
}while(i<50);
i=0;
do{
B[i] = A[i] + 5;
i++;
}while(i<50);Solution
Make sure there is only one exit condition among the loops.
