/* Evaluate an assertion E that is guaranteed to be true. | |
If NDEBUG is not defined, abort the program if E is false. | |
If NDEBUG is defined, the compiler can assume E and behavior is | |
undefined if E is false, fails to evaluate, or has side effects. | |
Unlike standard 'assert', this macro evaluates E even when NDEBUG | |
is defined, so as to catch typos, avoid some GCC warnings, and | |
improve performance when E is simple enough. | |
Also see the documentation for 'assume' in verify.h. */ | |
/* Check E's value at runtime, and report an error and abort if not. | |
However, do nothing if NDEBUG is defined. | |
Unlike standard 'assert', this macro compiles E even when NDEBUG | |
is defined, so as to catch typos and avoid some GCC warnings. | |
Unlike 'affirm', it is OK for E to use hard-to-optimize features, | |
since E is not executed if NDEBUG is defined. */ | |
