//
// This file defines the resources required by P9 instructions. This is part of
// the P9 processor model used for instruction scheduling. This file should
// contain all the instructions that may be used on Power 9. This is not
// just instructions that are new on Power 9 but also instructions that were
// available on earlier architectures and are still used in Power 9.
//
// The makeup of the P9 CPU is modeled as follows:
//   - Each CPU is made up of two superslices.
//   - Each superslice is made up of two slices. Therefore, there are 4 slices
//   for each CPU.
//   - Up to 6 instructions can be dispatched to each CPU. Three per superslice.
//   - Each CPU has:
//     - One CY (Crypto) unit P9_CY_*
//     - One DFU (Decimal Floating Point and Quad Precision) unit P9_DFU_*
//     - Two PM (Permute) units. One on each superslice. P9_PM_*
//     - Two DIV (Fixed Point Divide) units. One on each superslize. P9_DIV_*
//     - Four ALU (Fixed Point Arithmetic) units. One on each slice. P9_ALU_*
//     - Four DP (Floating Point) units. One on each slice. P9_DP_*
//       This also includes fixed point multiply add.
//     - Four AGEN (Address Generation) units. One for each slice. P9_AGEN_*
//     - Four Load/Store Queues. P9_LS_*
//   - Each set of instructions will require a number of these resources.
//===----------------------------------------------------------------------===//

// Two cycle ALU vector operation that uses an entire superslice.
// Uses both ALU units (the even ALUE and odd ALUO units), two pipelines
// (EXECE, EXECO) and 1 dispatch (DISP) to the given superslice.
