    Assuming you avoid all the push/pop and all the call/ret this would only be
    ~25% of the total instructions. There is just far too much logic and
    computation in there.

    % awk ' { print $5 } ' tracepoint-trace | sort | uniq -c | sort -rn
    222 mov
    57 push
    57 pop
    35 test
    34 cmp
    32 and
    28 jz
    25 jnz
    21 ret
    20 call
    16 lea
    11 add
