// Instruction scheduling annotations for in-order and out-of-order CPUs.
|
||
|
|
// These annotations are independent of the itinerary class defined below.
|
||
|
|
// Here we define the subtarget independent read/write per-operand resources.
|
||
|
|
// The subtarget schedule definitions will then map these to the subtarget's
|
||
|
|
// resource usages.
|
||
|
|
// For example:
|
||
|
|
// The instruction cycle timings table might contain an entry for an operation
|
||
|
|
// like the following:
|
||
|
|
// Rd <- ADD Rn, Rm, <shift> Rs
|
||
|
|
// Uops | Latency from register | Uops - resource requirements - latency
|
||
|
|
// 2 | Rn: 1 Rm: 4 Rs: 4 | uop T0, Rm, Rs - P01 - 3
|
||
|
|
// | | uopc Rd, Rn, T0 - P01 - 1
|
||
|
|
// This is telling us that the result will be available in destination register
|
||
|
|
// Rd after a minimum of three cycles after the result in Rm and Rs is available
|
||
|
|
// and one cycle after the result in Rn is available. The micro-ops can execute
|
||
|
|
// on resource P01.
|
||
|
|
// To model this, we need to express that we need to dispatch two micro-ops,
|
||
|
|
// that the resource P01 is needed and that the latency to Rn is different than
|
||
|
|
// the latency to Rm and Rs. The scheduler can decrease Rn's producer latency by
|
||
|
|
// two.
|
||
|
|
// We will do this by assigning (abstract) resources to register defs/uses.
|
||
|
|
// ARMSchedule.td:
|
||
|
|
// def WriteALUsr : SchedWrite;
|
||
|
|
// def ReadAdvanceALUsr : ScheRead;
|
||
|
|
//
|

|
|
// def ADDrs : I<>, Sched<[WriteALUsr, ReadAdvanceALUsr, ReadDefault,
|
||
|
|
// ReadDefault]> { ...}
|
||
|
|
// ReadAdvance read resources allow us to define "pipeline by-passes" or
|
||
|
|
// shorter latencies to certain registers as needed in the example above.
|
||
|
|
// The "ReadDefault" can be omitted.
|
||
|
|

|
||
|
|
// defined here.
