[RISCV] Add scheduling resources for V

[evandro]

Summary

Add the scheduling resources for the V extension instructions.

[khchen]

I'm curious about why there is no any load/store scheduling resources?

That's for another patch.

[NickHung]

I'm curious how instruction scheduling works if you don't add those resource models into the PseudoRVV instructions?

Firstly, this patch defines the resources. I'll follow it up with another patch.

[frasercrmck]

I've given it a quick once-over. Apologies if I've missed the mark in some of my comments; there might be reasons for some of them that I'm unaware of.

In general, I'm not seeing resources for mask reads? Should those be modeled?

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

353

Should this use ReadVIALUX?

438

Is this missing a read of an X resource?

484

Should this be WriteVFDivF?

739

ReadVNShiftV instead of ReadVShiftV?

741

ReadVNShiftV instead of ReadVShiftV?

757

Missing ReadVICmpX?

[frasercrmck]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

1017

Feels like there's too many read resources: VMV_V_V only has one operand?

1021

Again, too many read resources? VMV_V_X only has one operand.

1025

Too many read resources?

1146

Unsure here, but since this reads a scalar should it read something like ReadVFMergeF?

1153

Too many read operands? Should it read only something like ReadVFMovF?

1321

Missing read resource?

1360

Do all nfs 1,2,4,8 have the same 1V resource?

[craig.topper]

llvm/lib/Target/RISCV/RISCVSchedRocket.td

19

Does anything fail without this change? I assumed the UnsupportedFeatures list covered this.

[evandro]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

1321

I'll have to look at the specifics of the vd_wb and vd operands.

1360

No, this is scrap.

llvm/lib/Target/RISCV/RISCVSchedRocket.td

19

This is scrap. Actually, I expected to need the unsupported classes list with this. Alas, it seems to be necessary.

[evandro]

Add the mask operand.

[craig.topper]

llvm/lib/Target/RISCV/RISCV.td

232

Maybe include this from RISCVSchedule.td the way RISCVInstrInfo.td includes RISCVInstrInfoV.td?

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

1146

Do we need a Read for V0?

[evandro]

llvm/lib/Target/RISCV/RISCV.td

232

Other targets do it here, but I lean towards your suggestion.

[frasercrmck]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

1178–1185

It might not really be important but it's not immediately obvious to me what some of these abbreviations signify. VNCVTF narrow-converts int to float but VNCVTD narrow-converts float to float? Why F and D?

1303

How come ReadDefault? Also seems out of sync with VFMV_S_F below.

[evandro]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

1178–1185

Narrowing conversion from double to float or widening from float to double.

1303

I'd like to revisit how these instruction were defined in the near future.

[evandro]

Rebased.

[NickHung]

Adding those "sched" information into base RVV instructions seems redundant? The scheduler works on PseudoRVV instructions.
SchedReadWrite needs to consider pseudo instructions with LMUL? Their latency should be different.

Not redundant, as some tools do use the information at this level, e.g., llvm-mca.

Moreover, this patch captures the resources in a way that it makes it easier to add latency information to specific targets later.

SchedReadWrite needs to consider pseudo instructions with LMUL? Their latency should be different.

And SEW. I'm working on this feature, of which this patch introduces the preliminary information.

[evandro]

Rebase.

[evandro]

Add the scheduling resources for the V extension loads and stores.

[frasercrmck]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

810

Do the saturating instructions need resources for VXSAT/VXRM?

[HsiangKai]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

106

No scheduling resource for store value?

[HsiangKai]

You may need to rebase on main branch.

[evandro]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

810

It doesn't seem to me that sideband registers needs must be modeled for scheduling.

[craig.topper]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

794

Should ReadVLDX be ReadVSTX for VSE1_V?

1264

Should the last be ReadVMask?

1270

Should the last be ReadVMask?

1293

Why is this ReadVMIdxV and not ReadVMask?

llvm/lib/Target/RISCV/RISCVScheduleV.td

91

There are no X or I forms for extensions are there?

314

Is ReadVExtX used?

[HsiangKai]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

1178–1185

vfncvt.f.x.w  vd, vs2, vm       # Convert double-width signed integer to float.
vfncvt.f.f.w vd, vs2, vm        # Convert double-width float to single-width float.

These two are both to convert to single-width float. Maybe use DI, IF and DF to distinguish them?

1193–1200

Why the suffix changed to _IV_V? It is belong to OPMVV format.

1218–1221

Why is there VREDO_FV_V, but no VWREDO_FV_V?

1238–1245

The suffix could keep the same as before.

[craig.topper]

I think all my comments have been addressed. I think one suggestion from @HsiangKai is still open. @frasercrmck what do you think?

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

1178–1185

vncvt.f.f.w is also used for float to half. So using something that stands for "double" and "float" could be misleading.

[HsiangKai]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

1178–1185

I agree. It is misleading. How about use F_X and F_F just like the instruction name.
Besides the naming issue, the patch looks good to me.

[frasercrmck]

LGTM too, thanks @evandro! Just one last question I was wondering about regarding reductions.

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

547

I dunno if the first source of a reduction is likely to benefit from a different scheduling type than the second, since it's only reading the first element?

[evandro]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

547

I don't know either. It would probably be used with ReadAdvance.

1178–1185

The general scheme above is V{,W,N}CVT{I,F}_{I,F}V_VS2, where {,W,N} denotes the width of the result, whether the same, wider or narrower, and {I,F}, the type of the result, in the first instance, or of the argument, in the second instance, integer or FP.

[HsiangKai]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

1178–1185

LGTM.

[frasercrmck]

I'll formally LGTM given people seem happy overall.

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

547

Yeah possibly. We can cross that bridge when we come to it, I think.

[craig.topper]

LGTM

Hi, I am wondering is there any patch to construct Write/Read Sched for pseudo instructions with every different LMUL now? @evandro
