Subject: [dpdk-dev] [PATCH 1/3 v2] librte_hash: Fix unsupported instruction `crc32' in i686 platform
Date: Fri,  6 Mar 2015 00:55:30 +0800
Message-ID: <1425574530-16019-1-git-send-email-michael.qiu@intel.com> (raw)
In-Reply-To: <1425561339-13300-2-git-send-email-michael.qiu@intel.com>

CC rte_hash.o
Error: unsupported instruction `crc32'

The root cause is that i686 platform does not support 'crc32q'
Need make it only available in x86_64 platform

Signed-off-by: Michael Qiu <michael.qiu@intel.com>

v2 --> v1:
         Make crc32 instruction only works in X86 platform
