Re: Decision on Tumbleweed x86_64 Architecture level

You're confusing things. I know what x32 is and nobody cares about supporting it. (There was an aborted effort at porting Tumbleweed to the ARM equivalent of x32, fwiw) `file` is not going to tell you what instructions an executable contains, it only looks at the elf header. Try to compile an executable which runs a more complicated algorithm (copying an array of a dozen elements should suffice) with -march=i586 and x86-64. if you examine them in objdump, the second should contain SSE instructions.
