Hello, all
  
I have a assembly program (as following).That use the "MAX" constant.
But,i does not define it in the program.
When i assemble this program, it can be assembled successfully.
That mean that it does not have any error message.
But, this program is wrong because the "MAX"  value is unkonw.
 
My question is how to modify the GNU assembler source code or maybe i just add 
some option before i assemble the program. Then, if the assember encounter 
this unknow value,it can stop assemble and show the
value unknow error message.
                                                                               
 thanks a lot
