clang supports C11 atomic APIs just fine but Python's configure fails to detect it:
configure:16529: checking for stdatomic.h
configure:16545: clang -pthread -o conftest conftest.c -lpthread -ldl -lutil >&5
conftest.c:389:5: error: _Atomic cannot be applied to incomplete type 'void'
_Atomic void *py_atomic_address = (void*) &value;
^
1 error generated.
Indeed, the atomic uninhabited type is not very useful. If we wanted an atomic pointer, we should write _Atomic(void *). |
