Use SIMD operations in InitBlkUnroll/CopyBlkUnroll and increase unroll limit up to 128 bytes by echesakov · Pull Request #61030 · dotnet/runtime

echesakov · 2021-10-30T05:22:55Z

Currently, CodeGen::genCodeForInitBlkUnroll() and CodeGen::genCodeForCpBlkUnroll() do not use SIMD instructions when generating code for InitBlock/CopyBlock operations on Arm and Arm64.

This PR adds support for that on Arm64.

In order to accurately estimate whether the use of SIMD instructions is needed and/or whether the base address of a block needs to computed and stored to a integer register the algorithm does multiple passes - (one that verifies whether all offsets can be encoded and another that counts how many instructions will be emitted).

The following are justifications why such approach was chosen:

In a case when one of the instruction offsets can not be encoded the new implementation would "spill" the address of the beginning of the block to an integer register in order to avoid doing this multiple times as it is now.
In fact, that issue was already pointed out by a TODO comment (that is removed by the PR)

// TODO-ARM-CQ: If the local frame offset is too large to be encoded, the emitter automatically
// loads the offset into a reserved register (see CodeGen::rsGetRsvdReg()). If we generate
// multiple store instructions we'll also generate multiple offset loading instructions.
// We could try to detect such cases, compute the base destination address in this reserved
// and use it in all store instructions we generate. This would effectively undo the effect
// of local address containment done by lowering.

In other words it transforms a problem of code-generating of InitBlock(largeOffset, byteCount) to InitBlock(0, byteCount). In order to do figure out that such transformation is required, the algorithm needs a pass to verify whether all the offsets are encodable.

For example, the following snippet shows such case

 add xip1, fp, #0xd1ffab1e
- stp xzr, xzr, [xip1] // [V49 tmp34]- add xip1, fp, #0xd1ffab1e- stp xzr, xzr, [xip1] // [V49 tmp34+0x10]- add xip1, fp, #0xd1ffab1e- stp xzr, xzr, [xip1] // [V49 tmp34+0x20]- str xzr, [fp,#0xd1ffab1e] // [V49 tmp34+0x30]+ stp xzr, xzr, [xip1]+ stp xzr, xzr, [xip1,#16]+ stp xzr, xzr, [xip1,#32]+ str xzr, [xip1,#48]

In some cases using SIMD instructions would result in a longer instruction sequence(e.g. in InitBlockAllZeros(startOffset=8, byteCount=16)) since the JIT would need to initialize a SIMD register while it could just use a str xzr, xzr, [dstReg, #dstOffset] instead (assuming dstOffset is encodable). In order to figure out such cases I've chose to use the same mechanism of multiple passes instead of trying to "encode" all corner cases.

As an example, the following demonstrates a case where it is beneficial to "spill" that the base of address of destination in CopyBlock and use SIMD instructions than use integer instructions without spilling.

- ldp x1, x2, [fp,#80] // [V17 tmp13]- stp x1, x2, [fp,#24] // [V32 tmp28]- ldp x1, x2, [fp,#96] // [V17 tmp13+0x10]- stp x1, x2, [fp,#40] // [V32 tmp28+0x10]- ldp x1, x2, [fp,#112] // [V17 tmp13+0x20]- stp x1, x2, [fp,#56] // [V32 tmp28+0x20]- ldr x1, [fp,#128] // [V17 tmp13+0x30]- str x1, [fp,#72] // [V32 tmp28+0x30]- ;; bbWeight=0.50 PerfScore 7.50+ add xip1, fp, #56+ ldr x1, [xip1,#24]+ str x1, [fp,#24]+ ldp q16, q17, [xip1,#32]+ stp q16, q17, [fp,#32]+ ldr q16, [xip1,#64]+ str q16, [fp,#64]

In addition to that, the instruction selection strategy that the current implementation uses can be characterized as greedy "best fit" and it doesn't always produce the optimal result (for example, InitBlock sequence for 7 bytes is str rInitValue, [rAddr]; strh rInitValue, [rAddr+4]; strb rInitValue, [rAddr+6]). I changed the strategy slightly and added support to allow overlapping stores (so that sequence would become str rInitValue, [rAddr]; stur rInitValue, [rAddr+3].

The following is an example where using overlapping loads/stores result in shorter instruction sequence

 ldp x1, x3, [x0]
stp x1, x3, [x2,#16]
- ldr w1, [x0,#16]- str w1, [x2,#32]- ldrh w1, [x0,#20]- strh w1, [x2,#36]+ ldr x1, [x0,#14]+ str x1, [x2,#30]

I am also adding micro benchmarks to test performance impact of changes surrounding GT_STOREBLK (InitBlock/CopyBlock) in dotnet/performance#2154

FWIW, the current change is mostly CQ improvements with little effect on the performance. As you can notice, I am not changing INITBLK_UNROLL_LIMIT/CPBLK_UNROLL_LIMIT, but I am planning to do this as a follow up.

The following are the results of running the new micro benchmarks with the proposed increased INITBLK_UNROLL_LIMIT/CPBLK_UNROLL_LIMIT (to 128 bytes). There is 4% improvement for CopyBlock64 due to using SIMD instructions but the main performance gain would come from large block sizes due to eliminating a helper call.

nice solution, it looks like it was a lot of fun.

would not be assert(byteCount <= 16); less confusing?

does base mean no-simd?

should all reg be not REG_NA or does it allow some to be REG_NA?
