how about a test for the test suite ?  ".set" and "=" keep slipping in and 
causing us non-common peeps annoyances.  if a simple test grepped all of the 
test suite for those known patterns and barfed when found ...

the reason we havent been able to support "=" so far in the Blackfin assembler 
is due to the algebraic assembler syntax.  maybe Jie will be able to wrap his 
head around it though and rewrite the parser ... or at least get us "==" 
support since that will only occur in very few expressions ...
