I'm introducing a new machine model to simultaneously allow simple subtarget CPU descriptions and support new features of MachineScheduler. MachineModel has three categories of data: 1) Basic properties for coarse grained instruction cost model. 2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD). 3) Instruction itineraties for detailed per-cycle reservation tables. These will all live side-by-side. Any subtarget can use any combination of them. Instruction itineraries will not change in the near term. In the long run, I expect them to only be relevant for in-order VLIW machines that have complex contraints and require a precise scheduling/bundling model. Once itineraries are only actively used by VLIW-ish targets, they could be replaced by something more appropriate for those targets. This tablegen backend rewrite sets things up for introducing MachineModel type #2: per opcode/operand cost model. llvm-svn: 159891

Sorry, several patches in one. TargetInstrInfo: Change produceSameValue() to take MachineRegisterInfo as an optional argument. When in SSA form, targets can use it to make more aggressive equality analysis. Machine LICM: 1. Eliminate isLoadFromConstantMemory, use MI.isInvariantLoad instead. 2. Fix a bug which prevent CSE of instructions which are not re-materializable. 3. Use improved form of produceSameValue. ARM: 1. Teach ARM produceSameValue to look pass some PIC labels. 2. Look for operands from different loads of different constant pool entries which have same values. 3. Re-implement PIC GA materialization using movw + movt. Combine the pair with a "add pc" or "ldr [pc]" to form pseudo instructions. This makes it possible to re-materialize the instruction, allow machine LICM to hoist the set of instructions out of the loop and make it possible to CSE them. It's a bit hacky, but it significantly improve code quality. 4. Some minor bug fixes as well. With the fixes, using movw + movt to materialize GAs significantly outperform the load from constantpool method. 186.crafty and 255.vortex improved > 20%, 254.gap and 176.gcc ~10%. llvm-svn: 123905

ARM instruction itinerary fixes: 1. Cortex-a9 8-bit and 16-bit loads / stores AGU cycles are 1 cycle longer than 32-bit ones. 2. Cortex-a9 is out-of-order so model all read cycles as cycle 1. 3. Lots of other random fixes for A8 and A9. llvm-svn: 115121

// FIXME: If address is 64-bit aligned, AGU cycles is 1.
Major changes to Cortex-A9 itinerary. 1. Model dual issues as two FUs. 2. Model the pipelines correctly: two symmetric ALUs, the multiplier is a dependent pipeline on ALU0. The changes do not have much impact on codegen right now. But I plan to make pre-RA scheduler multi-issue aware which should take good advantage of the changes. llvm-svn: 115457

Change A9 scheduling itineraries VLD* / VST* entries default to "aligned". That is, it assumes addresses are 64-bit aligned (which should be the more common case). If the alignment is found not to be aligned, then getOperandLatency() would adjust the operand latency computation by one to compensate for it. rdar://9294833 llvm-svn: 129742

I'm introducing a new machine model to simultaneously allow simple subtarget CPU descriptions and support new features of MachineScheduler. MachineModel has three categories of data: 1) Basic properties for coarse grained instruction cost model. 2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD). 3) Instruction itineraties for detailed per-cycle reservation tables. These will all live side-by-side. Any subtarget can use any combination of them. Instruction itineraries will not change in the near term. In the long run, I expect them to only be relevant for in-order VLIW machines that have complex contraints and require a precise scheduling/bundling model. Once itineraries are only actively used by VLIW-ish targets, they could be replaced by something more appropriate for those targets. This tablegen backend rewrite sets things up for introducing MachineModel type #2: per opcode/operand cost model. llvm-svn: 159891

Cortex-A9 instruction-level scheduling machine model. This models the A9 processor at the level of instruction operands, as opposed to the itinerary, which models each operation at the level of pipeline stages. The two primary motivations are: 1) Allow MachineScheduler to model A9 as an out-of-order processor. It can now distinguish between hazards that force interlocking vs. buffered resources. 2) Reduce long-term maintenance by allowing the itinerary and target hooks to eventually be removed. Note that almost all of the complexity in the new model exists to model instruction variants, which the itinerary cannot handle. Instead the scheduler previously relied on processor-specific target hooks which are incomplete and buggy. llvm-svn: 163921

// The following definitions describe the simpler per-operand machine model.
// This works with MachineScheduler and will eventually replace itineraries.
I'm introducing a new machine model to simultaneously allow simple subtarget CPU descriptions and support new features of MachineScheduler. MachineModel has three categories of data: 1) Basic properties for coarse grained instruction cost model. 2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD). 3) Instruction itineraties for detailed per-cycle reservation tables. These will all live side-by-side. Any subtarget can use any combination of them. Instruction itineraries will not change in the near term. In the long run, I expect them to only be relevant for in-order VLIW machines that have complex contraints and require a precise scheduling/bundling model. Once itineraries are only actively used by VLIW-ish targets, they could be replaced by something more appropriate for those targets. This tablegen backend rewrite sets things up for introducing MachineModel type #2: per opcode/operand cost model. llvm-svn: 159891

let IssueWidth = 2; // 2 micro-ops are dispatched per cycle.

let LoadLatency = 2; // Optimistic load latency assuming bypass.
// This is overriden by OperandCycles if the
// Itineraries are queried instead.
MIsched: add an ILP window property to machine model. This was an experimental option, but needs to be defined per-target. e.g. PPC A2 needs to aggressively hide latency. I converted some in-order scheduling tests to A2. Hal is working on more test cases. llvm-svn: 171946

let ILPWindow = 10; // Don't reschedule small blocks to hide

// modeled strictly by reserving resources.
Added MispredictPenalty to SchedMachineModel. This replaces an existing subtarget hook on ARM and allows standard CodeGen passes to potentially use the property. llvm-svn: 161471

Cortex-A9 instruction-level scheduling machine model. This models the A9 processor at the level of instruction operands, as opposed to the itinerary, which models each operation at the level of pipeline stages. The two primary motivations are: 1) Allow MachineScheduler to model A9 as an out-of-order processor. It can now distinguish between hazards that force interlocking vs. buffered resources. 2) Reduce long-term maintenance by allowing the itinerary and target hooks to eventually be removed. Note that almost all of the complexity in the new model exists to model instruction variants, which the itinerary cannot handle. Instead the scheduler previously relied on processor-specific target hooks which are incomplete and buggy. llvm-svn: 163921

I'm introducing a new machine model to simultaneously allow simple subtarget CPU descriptions and support new features of MachineScheduler. MachineModel has three categories of data: 1) Basic properties for coarse grained instruction cost model. 2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD). 3) Instruction itineraties for detailed per-cycle reservation tables. These will all live side-by-side. Any subtarget can use any combination of them. Instruction itineraries will not change in the near term. In the long run, I expect them to only be relevant for in-order VLIW machines that have complex contraints and require a precise scheduling/bundling model. Once itineraries are only actively used by VLIW-ish targets, they could be replaced by something more appropriate for those targets. This tablegen backend rewrite sets things up for introducing MachineModel type #2: per opcode/operand cost model. llvm-svn: 159891

Cortex-A9 instruction-level scheduling machine model. This models the A9 processor at the level of instruction operands, as opposed to the itinerary, which models each operation at the level of pipeline stages. The two primary motivations are: 1) Allow MachineScheduler to model A9 as an out-of-order processor. It can now distinguish between hazards that force interlocking vs. buffered resources. 2) Reduce long-term maintenance by allowing the itinerary and target hooks to eventually be removed. Note that almost all of the complexity in the new model exists to model instruction variants, which the itinerary cannot handle. Instead the scheduler previously relied on processor-specific target hooks which are incomplete and buggy. llvm-svn: 163921

Cortex-A9 instruction-level scheduling machine model. This models the A9 processor at the level of instruction operands, as opposed to the itinerary, which models each operation at the level of pipeline stages. The two primary motivations are: 1) Allow MachineScheduler to model A9 as an out-of-order processor. It can now distinguish between hazards that force interlocking vs. buffered resources. 2) Reduce long-term maintenance by allowing the itinerary and target hooks to eventually be removed. Note that almost all of the complexity in the new model exists to model instruction variants, which the itinerary cannot handle. Instead the scheduler previously relied on processor-specific target hooks which are incomplete and buggy. llvm-svn: 163921
