// systems that support death tests. This allows one to write such a macro
// on a system that does not support death tests and be sure that it will
// compile on a death-test supporting system.
//
// Parameters:
// statement - A statement that a macro such as EXPECT_DEATH would test
// for program termination. This macro has to make sure this
// statement is compiled but not executed, to ensure that
// EXPECT_DEATH_IF_SUPPORTED compiles with a certain
// parameter iff EXPECT_DEATH compiles with it.
// regex - A regex that a macro such as EXPECT_DEATH would use to test
// the output of statement. This parameter has to be
// compiled but not evaluated by this macro, to ensure that
// this macro only accepts expressions that a macro such as
// EXPECT_DEATH would accept.
// terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
// and a return statement for ASSERT_DEATH_IF_SUPPORTED.
// This ensures that ASSERT_DEATH_IF_SUPPORTED will not
// compile inside functions where ASSERT_DEATH doesn't
// compile.
//
// The branch that has an always false condition is used to ensure that

// never executed. The unreachable code macro protects the terminator
// statement from generating an 'unreachable code' warning in case

//
// A "smart" pointer type with reference tracking. Every pointer to a
// particular object is kept on a circular linked list. When the last pointer
// to an object is destroyed or reassigned, the object is deleted.
//
// Used properly, this deletes the object when the last reference goes away.
// There are several caveats:
// - Like all reference counting schemes, cycles lead to leaks.
// - Each smart pointer is actually two pointers (8 bytes instead of 4).
// - Every time a pointer is assigned, the entire list of pointers to that
// object is traversed. This class is therefore NOT SUITABLE when there
// will often be more than two or three pointers to a particular object.
// - References are only tracked as long as linked_ptr<> objects are copied.
// If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
// will happen (double deletion).
//
// A good use of this class is storing object references in STL containers.
// You can safely put linked_ptr<> in a vector<>.
// Other uses may not be as good.
//
// Note: If you use an incomplete type with linked_ptr<>, the class
// *containing* linked_ptr<> must have a constructor and destructor (even
// if they do nothing!).
//
// Bill Gibbons suggested we use something like this.
//
// Thread Safety:
// Unlike other linked_ptr implementations, in this implementation
// a linked_ptr object is thread-safe in the sense that:
// - it's safe to copy linked_ptr objects concurrently,
// - it's safe to copy *from* a linked_ptr and read its underlying
// raw pointer (e.g. via get()) concurrently, and
// - it's safe to write to two linked_ptrs that point to the same
// shared object concurrently.
// TODO(wan@google.com): rename this to safe_linked_ptr to avoid
// confusion with normal linked_ptr.
