For one thing, with Ravenscar restrictions the compiler need not generate abort deferral related code, because without ATC it would be a dead code anyway. This might reduce the size of generated code and consequently make it faster. I have no hard data on what are the actual gains, however. There are certainly other opportunities as well. -- Maciej Sobczak * http://www.msobczak.com * http://www.inspirel.com
