jatin-bhateja · 2022-03-25T19:35:00Z

Summary of changes:

Patch re-uses existing C2 IR nodes and re-organizes LUT based JIT code sequence of VectorOperations.BIT_COUNT operation
for sub-word type (BYTE, SHORT) vectors over X86 targets supporting AVA2 and AVX512 features.
Efficient single instruction POPCOUNT instruction is emitted for applicable targets.

Kindly review and share you feedback.

So the SLP and the VectorAPI uses the same PopCountVL with different basic type?

Is it possible to separate this cast for SLP and always uses "T_LONG' as the basic type for PopCountVL ?

We can have type homogeneity for PopCountVL across VectorAPI and SLP once we start auto-vectorizing ConvL2I operation.

I think that makes the code hard to maintain, and I think @merykitty 's unaddressed comment in: openjdk/jdk#6857 (comment) is a preferable approach.

FYI: @fg1417 has a ConvL2I auto-vectorization support under review: openjdk/jdk#7806.

Yeah, so if the ConvL2I is supported to be auto-vectorized after then, the PopCountL is better to be auto-vectorized to "PopCountVL + VectorCastL2X" ? Do you have any plan on it? Thanks so much！

Agree to your proposal, once we have auto-vectorization for ConvL2I n place we can change the IR.

OK, thanks!

Agree to your proposal, once we have auto-vectorization for ConvL2I n place we can change the IR.

Here is an interim patch which type casts the result of PopCountVL into integer vector and thus prevent any special
handling in target specific backend implementations. But it seems more appropriate to generate correct IR snippet (PopCountL + ConvL2I) during scalar operation inline expansion and explicitly handle ConvL2I during auto-vectorization.

Comments need updating. Majority of comments above this method need to move to vector_popcount_byte. And then it is better to give comments at each step below in the method for easy review and maintenance. Please add comments to short, byte, long as well on similar lines.

New code has been modularized byte vector popcount is the leaf level operation and all the other primitive type operation build on top of it.

Without comments around the instructions it is very hard to review what the set of instructions are supposed to do.

From Vector API point of view it would be good to have the intrinsic for 256-bit/128-bit Long vectors as well.

This needs clarification in comments that the behavior is different based on vector api vs auto vectorizer. Have we tested this to work appropriately in both cases?

Yes, we do have explicit bit count tests in for auto-vectorizer flow to test this flow.

No auto vectorizer path here where the result in int vector for long vector.

Yes, because this is predicated operation pattern and auto-vectorizer does not support predicate operation inferencing.

The post loop work on the mainline would support the masked instructions generation.

Auto vectorizer restricts predication to load and store operations.

The assert needs to be removed on this path.

The assert needs to be removed on this path. Do you know why the testing didn't catch this?

Same a above, it should be OK to keep this as is since its already used in match_rule_supported method.

But this is !VM_Version::supports_avx512_vpopcntdq() so UsePopCountInstruction should have been false.

why are we using evex instruction for avx path?

AVX512 targets not supporting AVX512_POPCOUNTD feature can still have 64 byte vector operation, since long pop-count was only enabled for 512 bit vectors uptill now hence a down-casting EVEX instruction worked fine.

I see you fixed this is in your review comment resolution by adding a check for avx512vl around this instruction and a separate instruction generation for non avx512 path, thanks.

sviswa7 · 2022-04-08T23:47:33Z

Other than couple of comments above, rest of the patch looks good to me.

  // Use population count instruction if available.
-  if (supports_popcnt()) {
+  if (supports_popcnt() || supports_avx512_vpopcntdq() || supports_avx512_bitalg()) {


The UsePopCountInstruction is only for scalar popcont. Extending it to Vector popcount is causing lot of confustion. Let us keep it for scalar only as below:
if (supports_popcnt()) {
...
}

UsePopcountInstruction implies generating direct popcount instruction for targets which support it. A bit count operation can also be implemented without popcount as depicted by this patch.

I agree its adding some confusion since user may turn off UsePopcountInstruction and may want to generate optimized instructions for bit count over AVX2 targets using Vector API.

For SLP turning off UsePopcountInstruction will prevent creating scalar IR which will also inhabit inferencing of vector operation by auto vectorizer.

Could be replaced by:
predicate(is_pop_count_instr_target(Matcher::vector_element_basic_type(n->in(1))));
Also no need to check for UsePopCountInstruction any where as it is only meant for scalar popcount.

Thanks, I already cleaned this up, its used at couple of places and will refactor when I create mainline integration patch.

There is still a matcher path which can be chosen even if user turns off UsePopCountInstruction, relating this flag to an operation may not be correct. But I agree that to avoid any confusion we can remove its usage from pattern for the time being.
