}示例2: checkDeadSymbols
/// Cleaning up the program state.

CheckerContext &C) const {
if (!SR.hasDeadSymbols())
return;

// When one of the nonnull arguments are constrained to be null, nullability
// preconditions are violated. It is not enough to check this only when we
// actually report an error, because at that time interesting symbols might be
// reaped.

return;
