So the result was that barrier()s actually worked? Great.
BTW if you did this work it might be worthwhile to go one further step: gcc has a test suite where they run small programs and have a simple facility to scan the resulting assembler code for specific patterns. If you could bring your examples into that format (as in being stand alone compiled and have a simple "yes/no" pattern to check) and let it be included there that might make sure this always keeps working in the future.
