[RISCV] Add the zve extension according to the v1.0 spec

[eopXD]

Summary

zve is the new standard vector extension to specify varying degrees of
vector support for embedding processors. The zve extension is related
to the zvl extension and other updates that are added in v1.0.

According to https://github.com/riscv-non-isa/riscv-c-api-doc/pull/21,
Clang defines macro __riscv_v_elen, __riscv_v_elen_fp for zve and
it can be used by applications that uses the vector extension.

Do we need to define distinct SubtargetFeatures for each of these extensions or could they be broken down into a single MaxEEW feature (32 or 64) in conjunction with the pre-existing F/D features. This seems like it's more complicated than it needs to be.

llvm/lib/Target/RISCV/RISCVSubtarget.h

141

Is this correct? I thought we'd keep hasStdExtV as being the single-letter V extension, and Zve32x isn't that.

llvm/test/CodeGen/RISCV/attributes.ll

Why is this being changed in this patch?

[craig.topper]

llvm/test/CodeGen/RISCV/rvv/fixed-vectors-bitcast.ll

158

I believe this is coming from the nan-boxing for f16 in RISCVTargetLowering::splitValueIntoRegisterParts. The addition of +f must have changed PartVT from i32/i64 to f32. Even though we're using i32 for the return due to ABI.

[craig.topper]

llvm/lib/Target/RISCV/RISCVSubtarget.h

141

I just put up D112496 to stop using hasStdExtV everywhere.

[craig.topper]

clang/lib/Basic/Targets/RISCV.cpp

184

Would't ELEN be the correct term here? Not EEW.

[craig.topper]

llvm/lib/Target/RISCV/RISCV.td

182

I don't think it is quite that simple. Couldn't you have a scalar D and have zve64f vector?

[frasercrmck]

llvm/lib/Target/RISCV/RISCV.td

182

Yes, that's fair. Though I still think we can create a more intuitive system of Predicates to handle the TableGen aspects, as you've begun to do in D112496.

llvm/lib/Target/RISCV/RISCVSubtarget.h

141

Ah right now I see what this was trying to do. I think your patch helps things, thanks.

llvm/test/CodeGen/RISCV/rvv/fixed-vectors-bitcast.ll

158

Ah, interesting. I can't tell if that's a bug fix, i.e., if it's invalid to compile this test without f - though shouldn't we pass experimental-zfh by that same logic? Regardless, maybe we could split this off and pre-commit it?

please add a note in commit or comment here for those macros are proposed in the PR https://github.com/riscv-non-isa/riscv-c-api-doc/pull/21

184

https://github.com/riscv/riscv-v-spec/blob/master/v-spec.adoc#182-zve-vector-extensions-for-embedded-processors shows zve* extensions have Supported EEW, I guess it's why the term is EEW.

llvm/lib/Support/RISCVISAInfo.cpp

726–727

please update implication rule based on https://github.com/riscv/riscv-v-spec/issues/723#issuecomment-949542444

1. The Zve32f and Zve64f extensions depend upon the F extension
2. The Zve64d extension depends upon the D extension
3. The V extension depends upon the F and D

[craig.topper]

clang/lib/Basic/Targets/RISCV.cpp

184

Is that because that section talks about them as a set of values rather than a single maximum?

[eopXD]

llvm/lib/Target/RISCV/RISCVSubtarget.h

141

Thank you @craig.topper for the patch.
LGTM, and we can have it landed after this series on zvl, zve patch are done.

[eopXD]

Rebase.

[eopXD]

Rebase.

Address comment:

• implication rules for v and zve
  • zve64d imply d
  • zve*f imply f
  • d imply f
  • so since v imply zve64d, meaning v imply f and d

llvm/lib/Support/RISCVISAInfo.cpp

726–727

Thanks for the reminder. Addressed.

llvm/test/CodeGen/RISCV/attributes.ll

8

You are right. This should not be changed.

Removed.

[eopXD]

Remove dependency checks because new implications added.

[frasercrmck]

I think the rest of my comments would be to do with zvl so I'll leave it there to avoid repetition.

llvm/include/llvm/Support/RISCVISAInfo.h

65

Aside from the discussion about EEW vs. ELEN, something about the capitalization irks me. I realise we already have XLen but Eew looks... wrong. If other people disagree then that's fine.

llvm/lib/Support/RISCVISAInfo.cpp

67

Should this be in this patch? Or has some rebasing gone wrong and introduced code for D108694?

468

I'm not the most familiar with this API, but do we really need to checkDependency here when it's done in the next line?

693

Same here. Duplicate checkDependency?

737

Again, should zvl code be in this patch?

767

Really minor, but here you're using auto for StringRef but earlier and elsewhere it's auto &. I'm not sure which is preferred. Presumably StringRefs are cheap to copy and auto is fine? If auto & is more prominent in this file then go with that.

789

zvl patch?

[eopXD]

Sorry I mixed zvl patch when rebasing. I will remove it ASAP.

[eopXD]

Rebase correctly.

[eopXD]

Rebase.

Hi Fraser,
FYI, I think there is a discussion happening here.

[eopXD]

Under RISCV.td:
FeatureExtZve* -> FeatureStdExtZve*

[eopXD]

Clang-format.

[eopXD]

Rebase.

[eopXD]

Rebase.

[craig.topper]

I'd like to land my patch first and make this patch change hasVInstructions*() in the appropriate ways. If we don't do my patch first then this patch will enable i64 vectors with Zve32x which would be incorrect.

[eopXD]

Changes:

• Modify zve related predicate based on better interfaces by D112496.

[eopXD]

Changes:

• Rebase
• Since now the minimal extension to include is zve32x, zvlsseg and zvamo no longer implies v in RISCV.td
• Add implication: zve32x implies zvlsseg

[eopXD]

Update testcase since now zvlsseg don't imply v,
the testcases need to explicitly specify v.

[eopXD]

Fix test case fail:

• delete test case in`riscv-target-features.c` that specifies zvlsseg alone
• remove implication of zvlsseg -> v and zvamo -> v in RISCVISAInfo::toFeatures

[craig.topper]

llvm/lib/Target/RISCV/RISCVSubtarget.h

162–163

This needs to be the same as hasVInstructionsF32.

[craig.topper]

llvm/lib/Target/RISCV/RISCV.td

225

StdExtV depends on Zve64d which depends on FeatureStdExtZve64f which depends on FeatureStdExtZve32f which depends on FeatureStdExtZve32x. Do we need to check both hasStdExtV and hasStdExtZve32x here or could we just check hasStdExtZve32x?

[craig.topper]

llvm/lib/Target/RISCV/RISCV.td

224

Can we add the AssemblerPredicate to HasVInstructions and use that? Or we can rename it to HasVInstructionsAnyInt? Similar for HasStdExtZveFloating and HasVInstructionsAnyF.

And maybe rename HasStdExtVIntegerEEW64 to something like HasVInstructionsEEW64?

I'd like to avoid using the term "StdExt" in the name for something that isn't truly an extension name.

[eopXD]

Address @craig.topper 's comments on predicates in RISCV.td

[eopXD]

Change:
After adding extension zve, the minimum requirement of vector instructions isn't v.
Let __riscv_vector be indicator if any vector extension is available.

Sent a proposal to the riscv-c-api-doc: https://github.com/riscv-non-isa/riscv-c-api-doc/pull/22

[eopXD]

Update test case.

[eopXD]

Update code - add dependency checks in RISCVISAInfo

[eopXD]

Update testcase.

[eopXD]

Rebase to latest main.
Resolve conflict due to deletion of zvamo and addition of zfh, zfhmin.

[eopXD]

Rebase to latest main.

[eopXD]

clang/lib/Basic/Targets/RISCV.cpp

184

I think Zve is restricting the EEW, not ELEN.

[eopXD]

Rebase.

[eopXD]

Rebase again due to patch application fail.

[eopXD]

Update test case since v extension now depends on (implies) f and d extension.

[craig.topper]

clang/lib/Basic/Targets/RISCV.cpp

184

The spec defines ELEN as "The maximum size in bits of a vector element that any operation can produce or consume" That sounds like maximum EEW to me.

This statement appears in section 3.4.2

"For standard vector extensions with
ELEN=32, fractional LMULs of 1/2 and 1/4 must be supported. For standard vector extensions with ELEN=64, fractional
LMULs of 1/2, 1/4, and 1/8 must be supported."

I take "standard vector extensions with ELEN=32" to mean Zve32x, Zve32f.

And "standard vector extensions with ELEN=64" to mean Zve64x, Zve64f, Zve64d, and V.

Am I interpreting that incorrectly?

[eopXD]

clang/lib/Basic/Targets/RISCV.cpp

184

Yes I think you are correct. Maximum EEW is an alias of ELEN.

I see that the discussion in https://github.com/riscv-non-isa/riscv-c-api-doc/pull/21 hasn't conclude on whether changing the name into elen and elen_fp.

Should this patch pend until conclusions are drawn?

[eopXD]

Remove macro related code, lets add them later when conclusions are drawn.

[eopXD]

We can land non-macro related code for zve first and continue on proceeding patches.

[eopXD]

Update code.

[craig.topper]

llvm/include/llvm/Support/RISCVISAInfo.h

95

There's no definition for this

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

860–861

Is this deletion correct? I don't see where the VLUXEI64 instructions are declared now.

922

Why is there no Predicate on these aliases?

1576–1577

These require RV64 don't they?

[craig.topper]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

364

Why is this class only used for [64]

860–861

Oh I see, it's done with VIndexLoadStore<[64]>.

944

EEW64 indexed loads/stores also require RV64

[eopXD]

Address comments.
Thanks for reviewing!

[eopXD]

Update code

• Add macro __riscv_v_elen and __riscv_v_elen_fp

[eopXD]

clang/lib/Basic/Targets/RISCV.cpp

184

I see that the discussion has now concluded.
Thank you @craig.topper for pinging at the c-api PR.
Changing macro to __riscv_v_elen and __riscv_v_elen_fp

llvm/include/llvm/Support/RISCVISAInfo.h

65

Since we are changing to ELEN now I hope its less disturbing to you and I can resolve this ;)

[eopXD]

Rebase.

[craig.topper]

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

1577

The unit-stride and strided with EEW=64 don't require RV64. Just the indexed versions.

llvm/lib/Target/RISCV/RISCVSubtarget.h

162–163

Leave this line as an alias to hasVInstructionsF32()

165

This needs to check Zve32f not Zve32x I think?

166

This should check Zve64d not Zve64x I think?

[eopXD]

Address @craig.topper 's comments.
Thank you for reviewing.

Thank you for catching this.

[eopXD]

[craig.topper]

llvm/lib/Target/RISCV/RISCV.td

267

Zve32f requires F or Zfinx. It can't imply F.

287

Zve64d requires D or Zdinx. It can't imply D.

290

V can imply F and D though I think.

llvm/lib/Target/RISCV/RISCVInstrInfoV.td

957

Only the indexed load/stores require RV64 for EEW=64. Sorry I missed that when I caught it for the segment load/store.

llvm/lib/Target/RISCV/RISCVSubtarget.h

164

Zve32f I think since Zfh requires F.

165

I think we need to check HasStdExtF with Zve32f with a FIXME to consider HasStdExtZfinx in the future.

166

I think we need to check HasStdExtD with Zve64d with a FIXME to consider HasStdExtZdinx in the future

[eopXD]

Address @craig.topper 's comments.

[craig.topper]

llvm/lib/Support/RISCVISAInfo.cpp

725

I think we need to drop the implication of "f" here and "d" on zve64f. Move them to V

llvm/lib/Target/RISCV/RISCVSubtarget.h

167

Zfinx -> Zdinx

Yes. D should imply F now. Let me create a another patch for it as the current patch is for zve.

D already implies F in RISCV.td which is what is used for -mattr.
