## Summary - **Added** ARM64 NEON kernels for primitive comparisons. - **Covered** `int32`, `uint32`, `int64`, `uint64`, `float32`, and `float64`. - **Kept** narrow integer types and unsupported builds on the generic path. - **Handled** array/array, array/scalar, scalar/array, bitmap offsets, tails, NaNs, and unsigned boundary values. ## Benchmark Apple M1 Pro, 65,536 `int64` values, `nullprob=0.000000`, 3 runs with `-benchtime=1s`. The generic baseline uses `-tags noasm`. | Case | NEON | Generic | Speedup | | --- | ---: | ---: | ---: | | Array/scalar | 28.9-29.5 us/op | 78.5-79.2 us/op | ~2.7x | | Array/array | 30.3-30.9 us/op | 316.8-318.5 us/op | ~10.3x | Native uses 29 allocs/op versus 30 for the generic baseline in both cases. ## Tests - `go test ./arrow/compute/internal/kernels ./arrow/compute -count=1` - `go test -tags noasm ./arrow/compute/internal/kernels ./arrow/compute -count=1` - `go test -race ./arrow/compute/internal/kernels ./arrow/compute -count=1` - `go vet ./arrow/compute/internal/kernels` - Linux ARM64 and AMD64 cross-builds for the touched packages -- This is an automated message from the Apache Git Service.
