Subject [Impala-CR](cdh5-trunk) Use AVX2 operations to speedup Bloom filter insert by 10-50%.
Date Wed, 08 Jun 2016 16:16:40 GMT
Jim Apple has uploaded a new patch set (#2).

Change subject: Use AVX2 operations to speedup Bloom filter insert by 10-50%.
......................................................................

Use AVX2 operations to speedup Bloom filter insert by 10-50%.

Impala supports machines that do not have AVX2 instructions, so the
fast insert path is only conditionally enabled. This condition check
does not hurt Insert()'s speed.

I also needed to make a minor change to the order of libraries in
LD_LIBRARY_PATH when using the toolchain.
