Follow-up Comment #16, bug #27352 (project lwip): One possibility not mentioned is to pass ip_addr as a variable and not pointer to an ip_addr. When it's a u32_t the lack of concern for alignment is obvious. For IPv6 this means the typedef has to be a struct and it's passed by value by the compiler (with a copy). I don't think anyone requiring IPv6 can be worrying too much about performance - on some processors I don't even know if IPv6 makes sense. Do IPv6 and "light weight" fit in the same sentence? Option c) might be "Replace &(var_iphdr) with var_iphdr" _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?27352> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/
