I am not certain, but I'd assume yes. I used AVX in a JIT many
years ago in an experimental project. I see no reason why AVX2
wouldn't be available in ORC.<br>
<br>
Did you check with the results of sys::getHostCPUFeatures()?
There's lots of AVX variants:<br>

<br>
And maybe have a look how it works in JITTargetMachineBuilder:<br>
