Hi,everybody,

  I have one question about GNU ASM syntax. 
As I know:
__asm __volatile(
   "instructions"
   :output
   :input
   :exception);
In Linux, the restriction of output are "=m","=a", etc.
But I found in FreeBSD, there are "=m" and "+m".
I do not know the difference between "+" and "=". why?
Thank you!

Best Regards
  Ouyang Kai
