  inline assembly:

  
  __asm__(
                  "movl $(%ebx+4), %eax;" /* getting the operand in %eax */
                  "movl $0, %ebx;" /* ebx is the counter iand initializing it */
          "_start:"
                  "cmpl $0, %eax;"
                  "jz _final ;" /* if the comparison is 0 then jump to _final label */
                  "movl %eax, %ecx;"
                  "andl $1, %ecx;"
                  "cmpl $0, %ecx;"
                  "jz _skipadd;"
                  "addl $1, %ebx;"   /* if the last bit is set increment the counter */

          "_skipadd:"
                  "shrl $1, %eax;" /* dividing the number by 2 */
                  "jmp _start;"

          "_final:"            /* final location */
                  /* now we have to restore the registers */
                  "movl %eax, %ebx;"   /* storing the result in %eax */
                  "ret;"
   );
