### Description opt-in jdk.incubator.vector specializations for negate and abs unary expressions. Benchmarks look pretty nice: ``` 64,65: unary negate on a double column (companion to 15 which does long negate) SELECT SUM(-double1) FROM expressions SELECT SUM(-double4) FROM expressions 66,67: unary abs on long and double columns SELECT SUM(ABS(long4)) FROM expressions SELECT SUM(ABS(double1)) FROM expressions 68: unary abs of a binary subtraction (composes SIMD sub with SIMD abs) SELECT SUM(ABS(long1 - long4)) FROM expressions ``` ``` Benchmark (complexCompression) (deferExpressionDimensions) (jsonObjectStorageEncoding) (query) (rowsPerSegment) (schemaType) (storageType) (stringEncoding) (useVectorApi) (vectorize) Mode Cnt Score Error Units SqlExpressionBenchmark.querySql NONE singleString SMILE 64 1500000 explicit MMAP UTF8 false force avgt 5 16.052 ± 0.910 ms/op SqlExpressionBenchmark.querySql NONE singleString SMILE 64 1500000 explicit MMAP UTF8 true force avgt 5 5.294 ± 0.283 ms/op SqlExpressionBenchmark.querySql NONE singleString SMILE 65 1500000 explicit MMAP UTF8 false force avgt 5 13.288 ± 0.605 ms/op SqlExpressionBenchmark.querySql NONE singleString SMILE 65 1500000 explicit MMAP UTF8 true force avgt 5 3.085 ± 0.312 ms/op SqlExpressionBenchmark.querySql NONE singleString SMILE 66 1500000 explicit MMAP UTF8 false force avgt 5 10.602 ± 0.592 ms/op SqlExpressionBenchmark.querySql NONE singleString SMILE 66 1500000 explicit MMAP UTF8 true force avgt 5 5.687 ± 0.427 ms/op SqlExpressionBenchmark.querySql NONE singleString SMILE 67 1500000 explicit MMAP UTF8 false force avgt 5 15.691 ± 2.852 ms/op SqlExpressionBenchmark.querySql NONE singleString SMILE 67 1500000 explicit MMAP UTF8 true force avgt 5 5.186 ± 0.267 ms/op SqlExpressionBenchmark.querySql NONE singleString SMILE 68 1500000 explicit MMAP UTF8 false force avgt 5 15.786 ± 0.647 ms/op SqlExpressionBenchmark.querySql NONE singleString SMILE 68 1500000 explicit MMAP UTF8 true force avgt 5 10.682 ± 0.454 ms/op ``` -- This is an automated message from the Apache Git Service.
