Hi Daniel,

I think it's a bug in the back end not mangling @, but having had a  
quick glance at the AsmPrinter I don't think it's fixable without  
invasive changes to CodeGen because the mangling happens on the symbol  
with @ and $ inserted in it to indicate the symbol type in a few  
places.  I plan on taking a closer look when I have some more time.

There is a related bug with the PowerPC AsmPrinter that I want to look  
at; it was not mangling dots in symbol names (which seem to not be  
allowed by gas on PowerPC).
