However qemu sets it to `i686`. + +This was originally reported with docker-for-mac, but was reduced on `x86_64` which is why it is pointless +Steps to reproduce: +1. Compile the following for x86_64 (statically if you don't want have an x86_64 dynamic linker) (code originally from https://stackoverflow.com/questions/26520163/accessing-auxiliary-vectors-c) + +``` +#include <stdio.h> +#include <elf.h> + +int main(int argc, char** argv, char* envp[]) { + Elf64_auxv_t *auxv; + while(*envp++ != NULL); + + /*from stack diagram above: *envp = NULL marks end of envp*/ + int i = 0 ; + for (auxv = (Elf64_auxv_t *)envp; auxv->a_type != AT_NULL; auxv++) + /* auxv->a_type = AT_NULL marks the end of auxv */ + { + if( auxv->a_type == AT_PLATFORM) + printf("AT_PLATFORM is: %s\n", ((char*)auxv->a_un.a_val)); + } +} +``` +2.

Otherwise we just end up getting the 32-bit case. |
