| // The Cortex-A57 is a traditional superscalar microprocessor with a |
| // conservative 3-wide in-order stage for decode and dispatch. Combined with the |
| // much wider out-of-order issue stage, this produced a need to carefully |
| // schedule micro-ops so that all three decoded each cycle are successfully |
| // issued as the reservation station(s) simply don't stay occupied for long. |
| // Therefore, IssueWidth is set to the narrower of the two at three, while still |
| // modeling the machine as out-of-order. |
