Actually it does full Ada lexical and syntax analysis. I wrote the lexer and helped build the parser :). The parser is implemented using ayacc from UCI and the Ada grammer written by Herm Fischer. It is true that it only does semantic analysis on the extensions. One of the more interesting new features is persistent objects. Also SPS has made significant improvements in the run-time performance. Off the top of my head, message sends were down to 2.5 times the performance of a procedure call last time I worked with it. As for related products, there is a European product called Dragoon and I believe a proprietary tool that Harris Corp. has implemented.
