Somewhere I have read that modern Intel processors have low-level hardware for implementing exceptions and most compilers take advantage of it, to the effect that exceptions become faster than returning results state using variables.
Is it true? are exceptions faster than variables as far as returning state/responding to state? reading stack overflow on the topic seems to contradict that.
Thank you
I don’t know where you read this, but it is surely incorrect. No hardware designer would make exceptional circumstances, which are by definition uncommon, work FASTER than normal ones. Also keep in mind that C, which according to TIOBE is the most popular systems language, does not even support exceptions. It seems EXTREMELY unlikely that processors are optimized for ONE language’s exception handling, whose implementation is not even standardized among compilers.
Even if, somehow, exceptions were faster, you still should not use them outside their intended purpose, lest you confuse every other programmer in the world.
