IIRC these instructions are deliberately allowed in pre-armv8.3 targets because they are encoded in the NOP-space and can be deployed on pre-armv8.3 targets

These instructions are executed as NOP on pre v8.3-A architectures. It allows you to have a single compatible binary that works correctly on pre v8.3-a (ofc, without pointer authentication), as well as on
8.3-a and later cores, with pointer authentication.

Please, remove the predicates.

Is this change also correcting the options for the x2t99? I think that should be a separate patch if so.

Couple of question about this test.
Looks like you're both testing output on stdout and stderr, and your checks for this are interleaved. If I am not mistaken, the behaviour of this can vary on different platforms, and thus may fail on different platforms.

But more importantly, what is this test exactly testing? The file name gives away a hint of course, but I don't see yet how this interact with loop unrolling. Is the loop unroller looking at MaxInterleaveFactor that is set here, but is that what we are testing here?

I guess there won't be another define %val, it will be %val6, so this CHECK-NOT will never match even if there's another add?

In email Wei asked for help about he following error message:

And the comment from the person on the email was to define the instruction. The instruction is defined, as evidenced when table gen is run to produce the record-list. The error message can be suppressed by defining CompleteModele = 0, but that isn't correct, as there are models for those instructions.

However, I now note that at least In the output that Wei captured, it isn't complaining about the ThunderX3T110 model, but about Cyclone.

Hi Joel,
Thanks for your message, and apologies for not replying earlier to the updates; missed the notification.
I am now taking a closer at some changes I hadn't looked at. In the mean, some drive-by comments:

It is okay'ish to set CompleteModel = 0 if you're not interested in describing all instructions. The other way is of course to add the missing instruction to the model.

But first things first. @chill commented earlier about predicates. I also don't think you need to add HasV8_3a for the reason Momchill described, and there is still one left AArch64InstrInfo.td.

And while I am still looking into this, let me ask the question what I am wondering: why do you need to change the other scheduling models? These instructions are always supported, as a NOP, or otherwise.

[joelkevinjones]

We are trying to describe all instructions. The issue Wei is having is that the pointer auth instructions are being called out in the error message, but their timing information is defined—see the very end of AArch64SchedThunderX3T110.td for AUTDZA.

But first things first. @chill commented earlier about predicates. I also don't think you need to add HasV8_3a for the reason Momchill described, and there is still one left AArch64InstrInfo.td.

The changes to UnsupportedFeatures that was in every model has been taken out. I'm not sure why UnsupportedFeatures exists at all, but it isn't just AArch64 that has this.

Should the latest version be put up even if it fails on table-gen? That would make things easier to review.

One questions here, we want to model these instructions in our machine model, scroll down to line 1992-1997, in

However, if we remove this predicate here, tblgen will complain the following errors for all the instructions defined in line 1992-1997:

error: Incomplete schedule model

Anyone has clue why we have this problem? How should I model these instructions in the .md file.

Thanks,

[SjoerdMeijer]

Since debugging on phabricator is a bit difficult, I took the patch and had a little play. Now I actually remember seeing this before. I think the way this works is that when you describe new instructions (PA in this case) that other models don't have, they start complaining about incomplete models when they have set let CompleteModel = 1

I got things compiling with these changes:

1. leave all existing models untouched, revert those changes,

2. remove that predicate HasPA that you added,

3. Change this:

def SVEUnsupported : AArch64Unsupported {
let F = [HasSVE, HasSVE2, HasSVE2AES, HasSVE2SM4, HasSVE2SHA3,

• HasSVE2BitPerm]; + HasSVE2BitPerm, HasPA]; }

4. In your new model set:

let CompleteModel = 0;
list<Predicate> UnsupportedFeatures = SVEUnsupported.F;

5. This is where the problem is, comment out these descriptions in your model:

def : InstRW<[THX3T110Write_7Cyc_I1],
(instrs AUTDA, AUTDB, AUTDZA, AUTDZB, AUTIA, AUTIA1716, AUTIASP,
AUTIAZ, AUTIB, AUTIB1716, AUTIBSP, AUTIBZ, AUTIZA, AUTIZB,
PACDA, PACDB, PACDZA, PACDZB, PACGA, PACIA, PACIA1716,
PACIASP, PACIAZ, PACIB, PACIB1716, PACIBSP, PACIBZ,
PACIZA, PACIZB, XPACD, XPACI, XPACLRI)>;

I have never really looked into these instructions, and quick grep doesn't show any descriptions for some. For example, AUTDA doesn't exist. The others look aliases, perhaps they need a different treatment, or a regexp, I don't know, but perhaps you can take it from here.

[wxz2020]

I can confirm your findings, basically as long as we comment out the new instructions, it will be OK to build.

Agree with your changes 1), 2) and 3).

4. this seems does not matter to build, as long as we comment out the new instructions in 5), setting it "1" or "0", both are OK. they all can be compiled

5. if we comment out these instructions, then we will not be able to schedule them efficiently in the instruction scheduler. I know in other models or earlier versions, they could be treated as NOP, but in our new machine, they do have a timing effect, 7 cycles to finish. Any way to represent this in .md?

Thanks a lot for the help,

[joelkevinjones]

I don't think it makes sense to combine two unrelated things SVE and PA support into a combined thing. Since we already have UnsupportedFeatures in every sub-target .td file, I think it would be better to instead have:

def PAUnsupported : AArch64Unsupported {
  let F = [HasPA];
}

and modify each .td file to have

list<Predicate> UnsupportedFeatures = !listconcat(SVEUnsupported.F, PAUnsupported.F);

Agree. Methinks that this is easier to read.

[SjoerdMeijer]

Agreed about the UnsupportedFeatures list. But I just wanted to unblock this work, create a first version that compiles, so you can pick it up and clean things further up.

[wxz2020]

I put every people's feedbacks into the code and upload them here.

I think we can use it as the start point for TX3, and add more when we move on.

Thank you all for great help,

[wxz2020]

I will put the "PAUnsupported" predicate later once this got passed.

[SjoerdMeijer]

Let's separate out HasPA from SVEFeatures now while we are at it, probably it's more work to do this as a follow up, and after that this looks good to me.

Bonus points for adding some llvm-mca tests, see the llvm-project/llvm/test/tools/llvm-mca/ directory for some inspiration how this latencies can be checked, but that seems like something for follow-up.

just remove them then instead of commenting them out.

[wxz2020]

Removed the PA related instructions from the .md file as suggested.

[wxz2020]

I think I made all the changes mentioned in the feedbacks. Please take sometime to review the current version. We are eager to get the first thunderx3t110 checked in.

There are a few things we plan to do after the 1st version:

1. add more tests as suggested in the review
2. make changes to the predicate for clarity and easy readability
3. solve the PA instruction issue

Let me know if there is anything missing. Thanks,

Can you add what Joel suggested? I don't see the point of doing this as a follow up. This very simple thing is done half right here, so is best fixed here as there is no reason to leave this for another time; following up on this and talking about this is more work than just doing it.

[wxz2020]

Sure I will add Joel's suggestion and other fixes later.

Thanks,

[wxz2020]

1. Added the predicates as suggested
2. brought back the TargetParserTest.cpp which was missed last time

[wxz2020]

Fix the format issue in TargetParserTest.cpp

[wxz2020]

fix a typo, thunderx3t110, not thunderx3t100 in TargetParserTest.cpp

[SjoerdMeijer]

This looks good now, but sorry, one more request: I've just noticed a Clang driver test is missing. Can you add a test for this to clang/test/Driver/aarch64-cpus.c? And related to this, the relevant tests to llvm/unittests/Support/TargetParserTest.cpp?

[wxz2020]

1. in clang/test/Driver/aarch64-cpus.c, expanded the the same tests for thunderx2t99 to thunderx3t110
2. in llvm/unittest/Support/TargetParserTest.cpp, fix the missing target features

So far all the existing issues are fixed according to review feedbacks

Thanks

[wxz2020]

Correct the wrong version of llvm/unittests/Support/TargetParserTest.cpp which causes the test failure.

[SjoerdMeijer]

Joel will help me to commit it. Thanks,

I have a question here. Our customers need the TX3 support urgently, they asked me to put this TX3 support to LLVM 10.0.1 and if there is 9.0.2 release planned, they also need it there.

How can I do this? To put this checkin to LLVM 10.0.1 branch and 9.0.2 branch?

Is it possible? What steps I should follow?

Thanks,

[SjoerdMeijer]

Best to ask the release manager. Today Tom Stellard posted a message to the llvm dev list with subject:

[llvm-dev] LLVM 10.0.1-rc1 release update

So best to reply to this(*) asap with your query if it's possible to get this onto the branch.
