The program fir contains nested 2 loops, not context sensitive. The number of iterations of the inner loop is dependent on the iteration no. of the outer.

The number of iterations of the loops in the program is input dependent (in_data). The no. of iterations are the following:

No. of iterations for main_fir_filter_int_L1 = 10
Maximum no. of iterations per invocation for main_fir_filter_int_L1_L1 is 26, sum is 215
