using __asm__

[paul rodriguez]

	Hi. You can use something as:

static __inline__ void your_function(long *ptr_flag,long *ptr_usp)
{

    __asm__ __volatile__(

 	"mov (%0),%%r0 \n\t" 
 	"mov (%1),%%r1 \n\t"

        :
        : "r" (ptr_flag), "r" (ptr_usp)
        : "memory");

   return;
}

	where ptr_flag = &flag, ptr_usp = &usp  

	You can look into the kernel for more examples
