Well, there's also disallowing an implementation from using the "noinline" attribute-token to mean something different. I doubt the total isolation rule would be popular, though, or particularly meaningful. It would seem to disallow PGO, for one thing. [[noinline]] looks like a directive to disable the function inliner, which is useful in practical code is to reduce bloat. (I.e., an application with megabytes of laundry list code should be compiled to "threaded bytecode.") If indeed the proposal specifies it to disallow all interprocedural optimizations and not just some, it would reduce the practical value. (I rather doubt such can be stated in standard semantic terms.) -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
