Subject: [dpdk-dev] [PATCH] lib/librte_table: fix arm64 hash function selection
Date: Sat, 6 Apr 2019 13:29:41 +0000 [thread overview]
Message-ID: <20190406132852.14862-1-jerinj@marvell.com> (raw)
Message-ID: <20190406132941.nSNKKe12BaxKh6He6V9XLXY5UpA1-xExco4wmeFJGzY@z> (raw)
From: Jerin Jacob <jerinj@marvell.com>
Use CRC32 instruction only when it is available to avoid
the build issue like below.
{standard input}:16: Error:
selected processor does not support `crc32cx w3,w3,x0'
Fixes: ea7be0a0386e ("lib/librte_table: add hash function headers")
