Description

When using garrow_numeric_array_compare() to compare arrow array, I got 

 arrow::compute::aggregate::AddSumAvx512AggKernels()  called.

But my compute doesn't support avx512 instructions set, so it crashed and reported:

Program terminated with signal 4, Illegal instruction.

#0  0x00007efc082fe1d7 in arrow::compute::aggregate::AddSumAvx512AggKernels(arrow::compute::ScalarAggregateFunction*) () from /usr/local/lib64/libarrow.so.200

 

Is this a bug?

I found that  CXX_SUPPORTS_AVX512 flag is decided by whether compiler could compile with

-march=skylake-avx512 -mbmi2. In my opinion, these options is just tell the compiler try to compile with avx512, if not supported, it doesn't complain anything.
