; - When we create a MachineFunction (e.g, during instruction selection), it

; has a size of 0.
|
|
; - The initial size of the function after filling it is positive.

; - After that, we can increase or decrease the size of the function.
|
|
; - ... The final size must be positive.

; - ... The delta can be negative or positive.
