zhaorenhai created IMPALA-9645:
----------------------------------

             Summary: Port LLVM codegen to adapt aarch64
                 Key: IMPALA-9645
                 URL: https://issues.apache.org/jira/browse/IMPALA-9645
             Project: IMPALA
          Issue Type: Sub-task
            Reporter: zhaorenhai


 On aarch64, the Lowered type  of  struct \{bool, int128} is form \{ {i8}, \{i128} }. No padding add. This is different with x86-64, which is \{ {i8}, \{15*i8}, \{i128} } with padding add automatically.

And here also add some type conversion between x86 and aarch64 data types.

And also add some aarch64 cpu's feature.
