// 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.

// Map the target-defined scheduler read/write resources and latency for
// Cortex-A57. The Cortex-A57 types are directly associated with resources, so
// defining the aliases precludes the need for mapping them using WriteRes. The
// aliases are sufficient for creating a coarse, working model. As the model
// evolves, InstRWs will be used to override some of these SchedAliases.
//
// WARNING: Using SchedAliases is convenient and works well for latency and
//          resource lookup for instructions. However, this creates an entry in
//          AArch64WriteLatencyTable with a WriteResourceID of 0, breaking
//          any SchedReadAdvance since the lookup will fail.
