[arm64] JIT: Enable CSE/hoisting for "arrayBase + elementOffset" by EgorBo · Pull Request #61293 · dotnet/runtime

EgorBo · 2021-11-07T09:15:23Z

Usually, for a typical array access we create the following tree

arrRef + (index + elemOffset)

which is basically invariant1 + (X + invariant2), if we change it to:

(arrRef + elemOffset) + index

I assume it's safe from GC's point of view, both ADDs are byref and within the objects

we'll be able to hoist/CSE the invariant part arrRef + elemOffset on arm/arm64. We don't really need it on XArch because it will be handled by a more powerful addressing mode such as mov r9d, dword ptr [rdx+4*r9+16].
So, essentially, this PR changes morphing of GT_INDEX like this:

UPD Also, this PR folds LEA(BFIZ) into load/store with scale and sign/zero extension.

Example:

intTest(int[]array,inti,intj)=>array[i]+array[j];intSum(int[]array){intsum=0;foreach(intiteminarray)sum+=item;returnsum;}

some diffs we weren't able to fold cloned loops because of it, e.g. for:

privatestaticboolTest(byte[]prefix,byte[]byteArray){if(prefix==null||byteArray==null||prefix.Length>byteArray.Length)returnfalse;for(inti=0;i<prefix.Length;i++){if(prefix[i]!=byteArray[i])returnfalse;}returntrue;}

^ diff: https://www.diffchecker.com/oUPb1br3
We clone the loop in both my PR and Main, but in Main we then are able to drop it, but not it "PR" due to that CSE of ADD. Both loops don't have bound checks. Btw, number of bl CORINFO_HELP_RNGCHKFAIL is the same in base and diff diffs so I assume this PR doesn't regress bound check elimination.

Issue Details

Usually, for a typical array access we create arrRef + (index + elemOffset) tree which is basically invariant1 + (X + invariant2), if we change it to (arrRef + elemOffset) + index we'll be able to hoist/CSE the invariant part arrRef + elemOffset, Example:

intTest(int[]array,inti,intj)=>array[i]+array[j];intSum(int[]array){intsum=0;foreach(intiteminarray)sum+=item;returnsum;}

Overall it's a size regression due to additional CSEs, I noticed in some diffs we weren't even able to fold cloned loops because of it, e.g. for:
```csharp
private static bool Test(byte[] prefix, byte[] byteArray)
{
if (prefix == null || byteArray == null || prefix.Length > byteArray.Length)
return false;
for (int i = 0; i < prefix.Length; i++)
{
if (prefix[i] != byteArray[i])
return false;
}
return true;
}

^ diff: https://www.diffchecker.com/oUPb1br3
We clone the loop in both my PR and Main, but in Main we then are able to drop it, but not it "PR" due to that CSE of ADD. Both loops don't have bound checks. Btw, number of bl CORINFO_HELP_RNGCHKFAIL is the same in base and diff diffs so I assume this PR doesn't regress bound check elimination.

@EgorBo - It might be good to post PerfScore diff as well, will be good to understand if there is lot of regression in it. Also, do you mind posting the diffs for benchmark collection?

kunalspathak · 2021-11-08T19:48:38Z

From the diffs, it looks like most of them are also coming from loop alignment. Might be worth turning loop alignment off for baseline/test to see the real code size impact.

FWIW, I usually just cd into the directory SPMI created for diffs and jit-analyze -b base -d diff -m PerfScore directly.

You can use windows collection by passing -target_os windows -target_arch arm64 to the superpmi.py.

Looks like very good results.

A few minor questions.

BruceForstall · 2021-11-09T06:21:35Z

You should probably trigger jitstress, and also gcstress0xc to validate our assumption that GC will be happy with this new form of byref

EgorBo · 2021-11-09T13:21:57Z

Regression example:

privatestaticint[]_goto;privatestaticintTest(intdestpos){_goto[destpos]=AddBacktrackNote();return_goto[destpos];}

Here index is invariant and _goto arrayref is not (it can be changed in AddBacktrackNote) so in this case the default "arrRef + (index + elemOffset)" shape works better as we will be able to do CSE for (index + elemOffset). Unfortunately, it's not possible to detect patterns like this early in morph. Naïve approaches like "if index is lvParam" don't really work well.
So I'm suggesting we merge it as is and look at regressions in dotnet/performance on perf triage meetings (if there will be a lot of them - address them or revert the commit completely).

E.g. we can pick the shape based on heuristics:

Current block has BBF_BACKWARD_JUMP
ArrayRef or Index are parameters
Loop body has calls
etc..

A possible solution is a sort of tree re-association phase during CSE/LoopHoisting/VN e.g.
(invarian1 + x) + invariant2 --reassoc--> (invariant1 + invariant2) + x

@BruceForstall does it look good now? gcstress test failures are timeouts in Vector64_ro/Vector128_ro/Vector256_ro tests which are huge, I guess we might want to disable them for gcstress.

@kunalspathak I changed the code slighty, what I've done is basically converted ifdef-else into normal if-else and enabled that new shape (arrRef + elemOffset) + index only for primitive types, it significantly improved diffs, e.g. Benchmarks collections was:
1332 improved, 365 regressed
now:
1136 improved, 84 regressed

Most of the benchmarks you listed got fixed, BenchI.AddArray is still a size regression but overall it looks like a perf improvement actually: https://www.diffchecker.com/Msv0RBMs (less code in loops)

New diffs: https://gist.github.com/EgorBo/dd3b682f69ce2a530a8019c0e8bf46b2
