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. ## Troubleshooting -- cgit v1.2.3
