1 ; This tests the order in which functions are outlined in MachineOutliner
2 ; There are TWO key OutlinedFunction in FunctionList
4 ; ===================== First One =====================
13 ; - `SequenceSize=20` and `OccurrenceCount=6`
14 ; - each Candidate has `CallOverhead=12` and `FrameOverhead=4`
15 ; - `NotOutlinedCost=20*6=120` and `OutliningCost=12*6+20+4=96`
16 ; - `Benefit=120-96=24` and `Priority=120/96=1.25`
18 ; ===================== Second One =====================
25 ; - `SequenceSize=12` and `OccurrenceCount=4`
26 ; - each Candidate has `CallOverhead=4` and `FrameOverhead=0`
27 ; - `NotOutlinedCost=12*4=48` and `OutliningCost=4*4+12+0=28`
28 ; - `Benefit=48-28=20` and `Priority=48/28=1.71`
30 ; Note that the first one has higher benefit, but lower priority.
31 ; Hence, when outlining per priority, the second one will be outlined first.
