[PATCH 1/4] app: add LDFLAGS -latomic to link atomic lib

[Gavin Hu]

For ARM64 platform, libdpdk.a includes the librte_pmd_octeontx_ssovf.a,
which requires the libatomic.a support.The atomic lib is built-in in the
gcc toolchain, but for clang it has to be explicitly linked.
For more details, please refer to https://clang.llvm.org/docs/Toolchain.html

    event/octeontx: fix build with clang 6
    
    Clang 6 & 7 fail to naturally align packed structs due to this clang
    can't use 8byte atomic primitives and splits them into lesser atomic
    primitives. To use lesser atomic primitives we need to link
libatomic
    (-latomic), instead supply alignment attribute to the compiler.

Re: [PATCH 1/4] app: add LDFLAGS -latomic to link atomic lib

[Gavin Hu]

Hi Bruce,

CC=clang Meson build did not hit this issue.

The GNU Makefile using clang hit this issue:
make config T=arm64-armv8a-linuxapp-clang

Best Regards,
Gavin

Is an equivalent change also needed for the meson build too?

Following could be a shorter replacement.

rte_memcpy(ev, &m_data->response_info, sizeof(*ev));

Hi Yongseok,

We will make the commit message more verbose.
As for the error: This is a clang compiler issue:
drivers/net/mlx5/mlx5_rxtx_vec.c:37:
/home/sirdas/code/commitc/dpdk-stable-18.02.1/drivers/net/mlx5/mlx5_rxtx_vec_neon.h:170:24: error: too many arguments provided to function-like macro invocation
                          (uint16x8_t) { 0, 0, cs_flags,
                          rte_cpu_to_be_16(len),

Thank you
Sirshak Das.

Perhaps this fixes compilation issues clang6 + x86 too.

Please change the  subject line to start with raw/ifpga:....

Newly introduced #pragma pack(1) in the header file caused comipiling
