Summary: [C++][Gandiva] Fix gandiva crash in certain VM/CPU
combinations
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
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.
