> Loop optimization for SIMD in logical operators
> -----------------------------------------------
>
> Key: HIVE-11521
> URL: https://issues.apache.org/jira/browse/HIVE-11521
> Project: Hive
> Issue Type: Sub-task
> Reporter: Teddy Choi

> Priority: Minor
> Attachments: HIVE-11521.patch
>
>
> JVM is quite strict on the code schema which may executed with SIMD
> instructions, take a loop in ColOrCol.java for example,
> {code}
> for (int i = 0; i != n; i++) {
> outputVector[i] = vector1[0] | vector2[i];
> }
> {code}
> The "vector1\[0\]" reference would prevent JVM to execute this part of code
> with vectorized instructions, we need to assign the "vector1\[0\]" to a
> variable outside of loop, and use that variable in loop.
> This issues covers AND, OR, NOT logical operators.
