 // AtomicWord is a synonym for intptr_t, and Atomic32 is a synonym for int32,
 // which in turn means int. On some LP32 platforms, intptr_t is an int, but
 // on others, it's a long. When AtomicWord and Atomic32 are based on different
 // fundamental types, their pointers are incompatible.
 //
 // This file defines function overloads to allow both AtomicWord and Atomic32
 // data to be used with this interface.
 //
 // On LP64 platforms, AtomicWord and Atomic64 are both always long,
 // so this problem doesn't occur.
