//
// This built-in function implements an atomic compare and exchange operation.
// This compares the contents of *ptr with the contents of *expected. If equal,
// the operation is a read-modify-write operation that writes desired into
// *ptr. If they are not equal, the operation is a read and the current
// contents of *ptr are written into *expected. weak is true for weak
// compare_exchange, which may fail spuriously, and false for the strong
// variation, which never fails spuriously. Many targets only offer the strong
// variation and ignore the parameter. When in doubt, use the strong variation.
//
// If desired is written into *ptr then true is returned and memory is affected
// according to the memory order specified by success_memorder. There are no
// restrictions on what memory order can be used here.
//
// Otherwise, false is returned and memory is affected according to
// failure_memorder. This memory order cannot be __ATOMIC_RELEASE nor
// __ATOMIC_ACQ_REL. It also cannot be a stronger order than that specified by
// success_memorder.
