Implementing C11 atomics without it would be a > real challenge. what is the issue there? i still don't get what the standard mean by "generic function" in the c11 atomics specs i thought the compiler will do the hard work (providing __builtin_foo for every atomic foo) and libc just macro wraps those it is not clear if the atomic functions are reserved for external linkage (currently the text seems to require external linkage for them but i don't know how could that work) or if you can take the address of them and the standard does not seem to permit the use of atomic functions in signal handlers which would be useful
