9 /// This file defines two macro asserts.
10 
11 #include <cassert>
12 
13 /// This macro asserts that 'a' evaluates to true. In debug mode, this macro
14 /// will crash the program if the assertion evaluates to false. It (typically)
15 /// has no effect in release mode.
16 #define PP_DCHECK(a) assert(a)
17 
18 /// This macro asserts false in debug builds. It's used in code paths that you
19 /// don't expect to execute.
20 ///
21 /// <strong>Example:</strong>
22 ///
23 /// @code
24 /// if (!pointer) {
25 /// // Pointer wasn't valid! This shouldn't happen.
26 /// PP_NOTREACHED();
27 /// return;
28 /// }
29 /// // Do stuff to the pointer, since you know it's valid.
30 /// pointer->DoSomething();
31 /// @endcode
32 #define PP_NOTREACHED() assert(false)
