Please submit a bug report to your assembler provider, it is  
broken.  :-)

Beyond that, you can use:

@samp{%=} outputs a number which is unique to each instruction in the
entire compilation.  This is useful for making local labels to be
referred to more than once in a single template that generates multiple
assembler instructions.

If you looked in the manual and didn't find this the first time,  
please submit a patch that would have enabled you to find it,  
thanks.  You're not the only one to not be able to find it, thanks.
