I personally would rather not have to worry about machine instructions. I
would like to be able to assume that the compiler will produce machine
instructions that do what my C language source text says. To my mind, the
discussion is about what exactly I am saying, according to the language
definition, when I declare an lvalue volatile.

Not for portable code. Also, it's not obvious you need to do anything
special unless you understand where the language definition does not support
the end result you're trying to get.
