This patch reduces number of warnings from 53 to 40. It removes the usual false positives utilizing unaligned_uint*_t data types.
Signed-off-by: Jan Viktorin <viktorin at rehivetech.com> --- As far as I know, only a 64-bit unaligned access can be a problem for ARMv7. I found only one such occurence: 118 struct rte_mbuf * 119 rte_ipv4_frag_reassemble_packet(struct rte_ip_frag_tbl *tbl, 120 struct rte_ip_frag_death_row *dr, struct rte_mbuf *mb, uint64_t tms, 121 struct ipv4_hdr *ip_hdr) ... 133 psd = (unaligned_uint64_t *)&ip_hdr->src_addr; 134 /* use first 8 bytes only */ 135 key.src_dst[0] = psd[0]; 136 key.id = ip_hdr->packet_id; 137 key.key_len = IPV4_KEYLEN Is this a real issue? --- config/defconfig_arm-armv7a-linuxapp-gcc | 1 + 1 file changed, 1 insertion(+) diff --git a/config/defconfig_arm-armv7a-linuxapp-gcc b/config/defconfig_arm-armv7a-linuxapp-gcc index cbebd64..2482d91 100644 --- a/config/defconfig_arm-armv7a-linuxapp-gcc +++ b/config/defconfig_arm-armv7a-linuxapp-gcc @@ -39,6 +39,7 @@ CONFIG_RTE_ARCH_ARM_TUNE="cortex-a9" CONFIG_RTE_ARCH_ARM_NEON=y CONFIG_RTE_FORCE_INTRINSICS=y +CONFIG_RTE_ARCH_STRICT_ALIGN=y CONFIG_RTE_TOOLCHAIN="gcc" CONFIG_RTE_TOOLCHAIN_GCC=y -- 2.6.3
