Subject: [dpdk-dev] [PATCH v3 1/3] net/thunderx: disable PMD for older compilers
Date: Thu, 6 Apr 2017 18:05:09 +0100 [thread overview]
Message-ID: <20170406170511.22289-1-ferruh.yigit@intel.com> (raw)
In-Reply-To: <20170406134637.4484-1-ferruh.yigit@intel.com>
Disable for gcc < 4.7 and icc <= 14.0
PMD uses some compiler builtins and new compiler options. Tested with
gcc 4.5.1 and following were not supported:
option:
-Ofast
macros:
_Static_assert
__ORDER_LITTLE_ENDIAN__
__ORDER_BIG_ENDIAN__
__BYTE_ORDER__
__atomic_fetch_add
__ATOMIC_ACQUIRE
__atomic_load_n
__ATOMIC_RELAXED
__atomic_store_n
__ATOMIC_RELEASE
It is not easy to fix all in PMD, disabling PMD for older compilers.
