Arm64: Combine if conditions into compare chains by a74nh · Pull Request #79283 · dotnet/runtime

a74nh · 2022-12-06T16:41:49Z

Add a new stage optOptimizeCompareChainCondBlock in pass optOptimizeBools.

This aims to reduced the number of conditional jumps by joining cases when multiple conditions gate the execution of a block.

Example 1:
If ( a > b || c == d) { x = y; }

Will be represented in IR as:

 ------------ BB01 -> BB03 (cond), succs={BB02,BB03}
* JTRUE (GT a,b)
------------ BB02 -> BB04 (cond), preds={BB01} succs={BB03,BB04}
* JTRUE (NE c,d)
------------ BB03, preds={BB01, BB02} succs={BB04}
* ASG (x,y)

These operands will be combined into a single AND in the first block (with the first
condition inverted), wrapped by the test condition (NE(...,0)). Giving:

 ------------ BB01 -> BB03 (cond), succs={BB03,BB04}
* JTRUE (NE (AND (LE a,b), (NE c,d)), 0)
------------ BB03, preds={BB01} succs={BB04}
* ASG x,y

Example 2:
If ( a > b && c == d) { x = y; } else { x = z; }

Here the && conditions are connected via an OR. After the pass:

 ------------ BB01 -> BB03 (cond), succs={BB03,BB04}
* JTRUE (NE (OR (LE a,b), (NE c,d)), 0)
------------ BB03, preds={BB01} succs={BB05}
* ASG x,y
------------ BB04, preds={BB01} succs={BB05}
* ASG x,z

Example 3:
If ( a > b || c == d || e < f ) { x = y; }
The first pass of the optimization will combine two of the conditions. The
second pass will then combine remaining condition the earlier chain.

 ------------ BB01 -> BB03 (cond), succs={BB03,BB04}
* JTRUE (NE (OR ((NE (OR (NE c,d), (GE e,f)), 0), (LE a,b))), 0)
------------ BB03, preds={BB01} succs={BB04}
* ASG x,y

This optimization means that every condition within the IF statement is always evaluated,
as opposed to stopping at the first positive match.
Theoretically there is no maximum limit on the size of the generated chain. Therefore cost
checking is used to limit the maximum number of conditions that can be chained together.

Currently the cost checking limits to a maximum of three simple conditions. This is the same behaviour as GCC. Note that LLVM allows chains of much longer length.

Issue Details

Add a new stage optOptimizeCompareChainCondBlock in pass optOptimizeBools. This finds multiple JTRUE(CMP) blocks and combine them into a single JTRUE(AND(CMP,CMP)) block.

All If conversion to use these AND as the condition.

(Putting up a WIP patch as I've got a couple of issues to still work through.)

I'm getting an error compiling System.Number:NumberToStringFormat(). This is a big function!

With this optimise bools creates an AND chain connected to JTRUE node 001240. This is not If converted.

At the code generation stage, we'll generate something like:

cmp x1, x2
ccmp x3, x4, eq
beq label

The eq in the ccmp comes from the node for the cmp. The eq in the beq comes from the node for the ccmp.
To ensure this happens, during lowering the AND chain is contained within the JTRUE. Then in genCodeForJumpTrue(), we generate the chain (via genCodeForContainedCompareChain()), which returns the condition for use in the JTRUE.

However, NumberToStringFormat() is a big function. During linear scan, a COPY node is added. This is put at the bottom of the block. ie - between the JTRUE and the contained AND, giving the IR:

....
N455 ( 15, 14) [001250] -c-XG--N--- t1250 = * EQ int REG NA <l:$36f, c:$370>
/--* t1239 int +--* t1250 int N457 ( 22, 18) [003730] Jc-XG--N--- * AND void REG NA
N001 ( 1, 1) [004318] ----------- t4318 = LCL_VAR int V16 loc12 x10 REG x10
/--* t4318 int N002 ( 2, 2) [004319] ----------- t4319 = * COPY int REG x1
N459 ( 24, 20) [001240] ---XG------ * JTRUE void REG NA $VN.Void

Note that the AND has the contained flag set.

Now during the code generation, the entire AND chain is ignored (because it is contained). The COPY node generates a mov but then falls over with liveness asserts - it's trying to move a value from the AND chain, but the AND chain hasn't been generated yet! The COPY can't be moved before the chain for the same reasons.

Alternatively, I was thinking not to contain the AND chain within the JTRUE. Instead, the final AND would be marked as setting flags, and when generating JTRUE it would parse the chain to find the condition for the final compare. I think this is the way forward, but wanted to check before rewriting things.

@kunalspathak, @jakobbotsch what are your thoughts?

jakobbotsch · 2022-12-07T10:56:11Z

Yes, LSRA will spill and insert resolution nodes before the terminating nodes like JTRUE. It means we cannot in general contain things inside the JTRUE as the contained trees may be using locals that are no longer present in registers. @TIHan ran into the same problem in #76731 (before that, I did not realize this would be a problem). It would probably be possible to teach LSRA about this so that it could insert resolution after the JTRUE instead when necessary (by splitting the edge -- already done in some cases).

I think your suggestion is fine to make forward progress, assuming you validate that the AND comes right before the JTRUE, in the same way that other relops are handled.

a74nh · 2022-12-07T11:26:20Z

@TIHan ran into the same problem in #76731

A few months back, I spent about a half day trying to do this, then realised it was trickier than expected and gave up.

I think your suggestion is fine to make forward progress, assuming you validate that the AND comes right before the JTRUE, in the same way that other relops are handled.

ok, will go this way then. Thanks.

LSRA actually already handles the situation for other cases so it does not look that complicated to extend it:

LSRA actually already handles the situation for other cases so it does not look that complicated to extend it:

In the end not containing anything inside the JTRUE made it work fine. The AND node is just treated the same way as a CMP node. Containing inside a JTRUE would need a new pull request, as there would be quite a lot of changes not directly applicable here.

Been distracted elsewhere, but this is looking good now, so I'll be taking it out of draft shorty....

jakobbotsch · 2023-01-25T15:16:45Z

That's fine, this was also more of a general note regarding #76731 -- I just stumbled upon that LSRA code today.

a74nh · 2023-01-25T18:09:03Z

Taking this patch out of draft. It needs some more test cases in compareAnd3Chains, but otherwise I'm happy with it now.

optOptimizeCompareChainCondBlock() merges two compares into an AND chain.
Due to the the way the blocks flow, we currently only handle cases where the two conditions are ORed together.
See the large comment block for examples, and also the new tests.

Adding cases that are ANDed together would require a little more thought as it doesn't quite fit. You'd either need an OR or ANDNOT chains or epiologues mid block - I've not fully considered how it'd work.

optOptimizeBools() now iterates through bocks in reverse order, this allows for multiple conditions to be chained. It doesn't seem to have caused any issues with the other optimizations there.

The rest of the changes are to support JTRUE having an AND child.

In particular, AND chains can only be reversed by adding a NOT on the front of the chain. The changes in fgopt and ifconversion make sure that AND chains are never reversed.

Getting the chain code working in lowering/codegen was a little fiddly.

I've taken care to avoid code size regressions. In particular, avoiding optimising where the code would normally generate a CBZ or TST instruction. The handful of regressions remaining are due to the immediate size in a CCMP instruction being smaller than a CMP instruction.

jakobbotsch · 2023-03-16T12:44:50Z

Given this is a lowering issue, and the low number of regressions (+416 bytes) compared to improvements (-148,480 bytes) is it ok to leave that for a later PR?

Yes, that's completely fine -- thanks for checking the regressions in this level of detail.

a74nh · 2023-03-16T13:59:07Z

Yes, that's completely fine -- thanks for checking the regressions in this level of detail.

Ok, in that case I think this patch is ready then. Looks like the failing test is a known error. And I think I've addressed all the review comments.

Did you end up adding some handling for potentially expensive trees somewhere else?

We're iterating forwards through the blocks now, so that I think gets rid of that issue:
if (expensive1 || cheap1 )
both of expensive1 and cheap1 would be checked against cost 7.
if (expensive1 || cheap1 || cheap2 )
First iteration both of expensive1 and cheap1 would be checked against cost 7.
If first iteration passed, then second pass the combined (expensive1+cheap1) would be checked against 35 and cheap2 against 7.
If first iteration failed, then both cheap1 and cheap2 would be checked against 7.
if (cheap1 || cheap2 || expensive1)
both cheap1 and cheap2 would be checked against cost 7. Which would pass.
Then (cheap1+cheap2) against 35 and expensive1 against 7.

It's odd to me that it's possible to "defeat" the check:
[MethodImpl(MethodImplOptions.NoInlining)]publicstaticintFoo(inta,intb){if(a>10&&(((a*a*a*a*a>3)&(a==20))!=false)){return42;}return100;}
this produces:

Of course it's a very constructed example but I would be afraid that there are more natural looking examples.
I suppose to fix this you would need the recursive walk you wanted to avoid. I don't think that's expensive -- the code below calls gtSetEvalOrder and fgSetStmtSeq and they both end up doing these kinds of full tree walks anyway -- but it's not as elegant. It would make me feel a bit more at ease, however, to find and limit the cost of each "leaf" in the compare chain.

I think we can leave it as is, it's probably fine in practice. Will leave it up to you.

The cost of (((a * a * a * a * a > 3) & (a == 20)) is 35, which is on the limit for combing with the a > 10
Whereas the cost after combining, for example, op1 > 3 && op2 == 10 && op3 >= 12 is 32. (It's fairly high because of the two lots of EQ(AND,0)).
Looking at this again, a limit of 35 is probably too high as it's allowing 4 items to chain together. I should probably drop it to 31 to prevent op1 > 3 && op2 == 10 && op3 >= 12 combing with anything else.

With the new costing it'll still allow like (((a * a * a * a > 3) & (a == 20)) (ie one less than you had before).
To improve it, further I think we'd have to somehow remove all the EQ(AND,0) blocks from the costings (as we know they'll vanish during lowering). Not sure it's worth it, so happy to leave as is now.
