[X86] Split FeatureFastVariableShuffle tuning into Lane-Crossing and Per-Lane variants

[lebedev.ri]

Summary

Currently, X86 backend only has a global one-size-fits-all FeatureFastVariableShuffle feature,
which controls profitability of both the cross-lane and per-lane variable shuffles.
I guess, this has been fine so far.

But at least on AMD Zen 3, while per-line variable shuffles (e.g. VPSHUFB)
are as fast as as shuffles with fixed/immediate mask,
while lane-crossing shuffles, e.g. VPERMPS is performing worse.

So to get the benefits of variable-mask shuffles, but not the drawbacks of lane-crossing shuffles,
as suggested by @RKSimon, split the feature flag into two.

*Please* double-check that i correctly deduced where we meant per-lane vs. cross-lane shuffles.

This one is weird. I'm not sure why fast-ness of variable shuffles matters here.

You mean because it's just AND/FAND not a shuffle? Fastness was added to AllowVariableMask later. Initially it was just the depth check. Probably guarding the constant pool?

Yes.

Yes, i think so.

If possible I'd make the znver3 change as a followup so its separate from this refactor.

We never decided whether to always allow per/cross lane shuffles for avx512 capable targets as they all have decent variable shuffle units (the only case that is bad seems to be KNL's PSHUFB, which we've never cared strongly about.) - which would allow us to clean up a lot of the tests below.

36099

Yeah its a legacy thing, and we don't have any good way to gauge the impact of vector constant masks in isel, so we're just a bit cautious :(

[lebedev.ri]

@craig.topper @RKSimon thank you for taking a look!

Yep, i'll be committing this separately.
It just made sense to me to submit the review in bulk, to show motivation
(because i'm not adding test coverage for the +fast-variable-crosslane-shuffle standalone,
because nothing currently would make use of that.)

llvm/lib/Target/X86/X86ISelLowering.cpp

Though, if i change the guard to

36099

Yep. I've poked at this, and i'm not sure if/how we could lift it,
all i tried seemed to make things not better. But then maybe
things are already bad in-the-wild, and we just don't know that because of tests..

So i'm personally mostly fine with the AllowVariablePerLaneMask guard here as it is now.

disregard, forgot to delete

[lebedev.ri]

Drop the Znver3 change itself.
Please let me know if there was some other review feedback
that i was supposed to address, i'm not sure if this is good to go?

[RKSimon]

I'm happy with this but I do think we should always enable variable shuffles (both types) on all AVX512 targets as well (and maybe land that first to simplify this patch) - @pengfei @craig.topper what do you think?

The patch seems NFC for the existing targets to me, though I don't have a deep cognition on the shuffles' cost. No objections from me.

Nit, are pre-lane shuffles always fast if the target has fast cross-lane shuffles? In this mean, we can keep FeatureFastVariableShuffle and make it implicate FeatureFastVariablePerLaneShuffle. So that we can reduce the changes?

Assumptions like this is pretty much why i'm having to do this change in the first place...
Could you please specify, *what* specific changes would be simplified by that?
I'm not really seeing it.

llvm/lib/Target/X86/X86.td

326–334

I meant if we define it like

def FeatureFastVariableShuffle
    : SubtargetFeature<"fast-variable-shuffle",
                       "HasFastVariableShuffle",
                       "true", "Shuffles with variable masks are fast",
                       [FeatureFastVariablePerLaneShuffle]>;

then we can keep most use of FeatureFastVariableShuffle unchanged.
Anyway, it is just nitpicking.

[lebedev.ri]

Thank you for taking a look!

I think the current status is more consistent and perhaps more future-prof/testable,
but i don't think i care enough to argue. I just want to make forward progress with the least latency :)

[lebedev.ri]

@pengfei @craig.topper @RKSimon does anyone feel strongly regarding the avx512 question and the question about not having fast-variable-crosslane-shuffle?

No questions from me, thanks.

[lebedev.ri]

Well, okay then. The changes here are pretty mechanical,
and are NFC for all the existing targets.
Thanks everyone!
