How do you detect the CPU architecture type during run-time with GCC and inline asm?

Question

I need to find the architecture type of a CPU. I do not have access to /proc/cpuinfo, as the machine is running syslinux. I know there is a way to do it with inline ASM, how

How many bugs can you fit in so few lines ;)

Try

static int is64bit(void) {
        int iedx = 0;
        asm volatile ("movl $0x80000001, %%eax\n"
                "cpuid\n"
        : "=d"(iedx)
        : /* No Inputs */
        : "eax", "ebx", "ecx"
        );

        if(iedx & (1 << 29))
        {
                return 1;
        }
        return 0;
}
