[Bug target/84522] GCC does not generate cmpxchg16b when mcx16 is used

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84522 --- Comment #4 from Ruslan Nikolaev --- I guess, in this case you would have to fall-back to lock-based implementation for everything. But does C11 even require that atomic_load work on read-only memory?
