"Memory model aware" sounds too generic. The same page [1] also makes it clear that the built-in functions match the requirements for the C11 memory model.
There are also several patches merged in the past which do not use the term "memory model aware". I would prefer to be consistent. [1] https://gcc.gnu.org/onlinedocs/gcc/_005f_005fatomic-Builtins.html
