Ok, here's a patch candidate that does tracking of most common N values. For your test-case I can see:
pr69678.gcda: 01a90000: 18:COUNTERS indirect_call 9 counts
pr69678.gcda: 0: 350000000 1868707024 175000000 969338501 175000000 0 0 0
pr69678.gcda: 8: 0
So for now, you'll need to generalize get_most_common_single_value to return
N most common values.
Eventually we'll need to renamed the counter as it won't be tracking just a single value
any longer. I can take care of it.
Can you please verify that the patch candidate works for you?
