[jira] [Created] (IMPALA-6304) Consider re-enabling AVX512 codegen

Tim Armstrong created IMPALA-6304:
-------------------------------------

             Summary: Consider re-enabling AVX512 codegen
                 Key: IMPALA-6304
                 URL: https://issues.apache.org/jira/browse/IMPALA-6304
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 2.11.0
            Reporter: Tim Armstrong
            Priority: Minor


LLVM 5.0 appears to fix the bugs that we were hitting with IMPALA-6291 (I successfully ran exhaustive release and exhaustive debug).

This is not particularly important at the moment, but blocks AVX512 instructions being emitted by codegen.
