With the patch, while dpdk itself is compiled, applications failed with= below error: ------------------------------- include/rte_memcpy.h:629:2: error: implicit declaration of function '_mm_al= ignr_epi8' [-Werror=3Dimplicit-function-declaration] /home/vithals/adu_src/build/x-men_dev/Default/shumway/infra/dpdk/shumway_ob= j/lib/../include/rte_memcpy.h:629:2: error: incompatible type for argument = 2 of '_mm_storeu_si128' ------------------------------- After including -mssse3 flags, compilation (cross compiled for a x86 linux = based platform) went through. Now the question is, when this binary is loa= ded on system that doesn't support SSSE3 instruction set (but just sse2 etc= ), what would be the behavior? Thanks, -Vithal
