However, in the second example, we can make a more aggressive assumption: because the undef is allowed to be an arbitrary value, we are allowed to assume that it could be zero. Since a divide by zero -it has <em>undefined behavior</em>, we are allowed to assume that the operation +has <em>undefined behavior</em>, we are allowed to assume that the operation does not execute at all. This allows us to delete the divide and all code after it: since the undefined operation "can't happen", the optimizer can assume that it occurs in dead code. |
