> Key: ARROW-12154
> URL: https://issues.apache.org/jira/browse/ARROW-12154
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++ - Gandiva
> Reporter: Projjal Chanda
> Assignee: Projjal Chanda
> Priority: Major
>
> When running gandiva in a VM where the VM doesn't provide all the features of
> the host cpu, specifically vector instructions like avx512 which needs vm
> support (because VM is older version and doesn't support them, or passthrough
> is disabled for these features), llvm::sys::getHostCPUName detects the
> processor with these features and so gandiva generates jit compiled code with
> these vector instructions, which the guest OS is unable to execute and hence
> faults.
