Comments show subtotals, and there are two types:
- - `[A .. T0/T1]`
- - `[B/A .. T0/T1]`
+ - `[A .. T0]`
+ - `[B/A .. T1/T0]`
Where A, B, T0 and T1 are:
- A is the number of cycles of current instruction. In case of a conditional
instruction, this is the value when the condition is not met.
- B is the number of cycles of current instruction when the condition is met.
- - T0 is the subtotal assuming all the conditionals were not met.
- - T1 is the subtotal assuming all the conditionals were met.
+ - T0 is the subtotal when the conditional is met.
+ - T1 is the subtotal when the conditional is not met.
