Umm ... what does this have to do with the discussion, which was about C++ vs. Ada, or perhaps C vs. Ada? Of course you can write lock-free algorithms equally well in all the languages in question. Of course all these languages allow machine-code inserts, and of course you can't know from the language standard what the compiler does with them. If you have evidence to the contrary, let's hear it. - Bob
