Apparently the GNU assembler has a HUGE hack to be compatible with really old and broken AT&T syntax assemblers.  The problem with this hack is that *SOME* forms of the fdiv and fsub instructions have the 'r' bit inverted. This was a real pain to figure out, but is trivially easy to support: thus we are now bug compatible with gas and gcc.
