avf: fix gcc compiling warning on Arm
Initializing struct avf_ip6_psh by {0} using gcc with O2 optimize option will trigger the -Werror=maybe-uninitialized compiling warning on Arm because gcc compiler will think some members of the struct avf_ip6_psh may not be initialized, which probably is a false positive in this case. The compiling error log is shown as below. Avoid this compiling warning by explicitly declaring the IPv6 src and dst ip in avf_ip6_psh as ip6_address_t. ccache /usr/lib/ccache/gcc-10 -DHAVE_FCNTL64 -DHAVE_GETCPU -DHAVE_MEMFD_CREATE -I/home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src -I. -Iinclude -I/home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/plugins -Iplugins -Iplugins/avf -Wno-address-of-packed-member -g -fPIC -Werror -Wall -march=armv8-a+crc -O2 -fstack-protector -DFORTIFY_SOURCE=2 -fno-common -fPIC -DCLIB_MARCH_VARIANT=cortexa72 -march=armv8-a+crc+crypto -mtune=cortex-a72 -DCLIB_N_PREFETCHES=6 -MD -MT plugins/avf/CMakeFiles/avf_plugin_cortexa72.dir/output.c.o -MF plugins/avf/CMakeFiles/avf_plugin_cortexa72.dir/output.c.o.d -o plugins/avf/CMakeFiles/avf_plugin_cortexa72.dir/output.c.o -c /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/plugins/avf/output.c In file included from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/vector_funcs.h:41, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/vector.h:196, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/string.h:48, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/mem.h:49, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/vec.h:42, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/format.h:44, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/elf.h:41, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/elf_clib.h:41, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vlib/vlib.h:44, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/plugins/avf/output.c:18: /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/plugins/avf/output.c: In function ‘avf_device_class_tx_fn_cortexa72’: /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/byte_order.h:59:10: error: ‘*((void *)&psh+32)’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 59 | return __builtin_bswap16 (x); | ^~~~~~~~~~~~~~~~~~~~~ /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/plugins/avf/output.c:115:23: note: ‘*((void *)&psh+32)’ was declared here 115 | struct avf_ip6_psh psh = { 0 }; | ^~~ Type: fix Change-Id: I2684b101b07823dfacc4a56cc29d152828d0cf37 Signed-off-by: Jieqiang Wang <jieqiang.wang@arm.com> (cherry picked from commit 3daf1f5d3a5918564ae2acdd748b24acaef5bce0)
