This comes down to whether a compiler can reduce this:
a * n / n
to just 'a'. gcc can do that even at -O0. But it can give different
results to implementations that do the discrete steps, when a*n overflows.
It would also give different results to 'a * m / n', when m and n happen
to have the same value.
For such reasons, I prefer to have the discrete steps, even if I don't
expect an overflow.

So this is a valid optimisation in C, since integer overflow is UB. The
compiler can assume that "a * n" does not overflow - or if it does, you
don't care what happens or what results you get. And when there is no
overflow, "a * n / n" is the same as "a". Thus a good compiler will
make this optimisation (unless it has some specific definition of
overflow behaviour).

By the same logic as above, if m and n are equal then the compiler can
reduce the expression to just "a". (It can even do that if they are
both equal to 0.) However, a compiler would need to know that they are
equal to take advantage of that situation. It is quite unlikely that
you'd see that in practice.

You prefer such code to be larger and slower than necessary? There's no
accounting for taste.

Can you please elaborate on the case when 'm' and 'n' are known to the
compiler to be both '0', how that, the 'm/n', can be "optimized away".
The evaluation of a plain 'a' is certainly different from an illegal
division by zero in 'a*0/0'.
My understanding is that such sub-expressions should not be allowed to
be transformed ("optimized") that way in any case. Optimization needs
also constraints, IMO.

Overflow is not the only issue, either overflow or division by 0
results in undefined behavior. A compiler may replace `a * n / n`
with just `a`, because either all the operations have well defined
results (and the final result is `a`) or the behavior is undefined
(and `a` is just as valid a result as anything else).
(INT_MIN / -1 overflows, but I don't think that can happen in this
particular case unless there's already UB for another reason.)

If the compiler knows m and n to be zero, then the behavior of m/n
is undefined, and a compiler can generate code that yields 0.

Division by zero is not "illegal"; the C standard doesn't generally use
that term. It has undefined behavior. A compiler is not required to
detect it, and no diagnostic is required.

Should they be allowed? Maybe. Are they allowed by the standard? Yes.

Sometimes the language details don't match intuition a programmer might have from other experiences or languages. Sometimes programmers make mistakes, despite all their knowledge, experience and care. And compilers can only read the source code given - they are unable to read the minds of programmers, or even their comments in the code. There is always scope for improvement. C courses, tutorials and books could do a better job at pointing out details of C semantics. The C standards could be clearer, with more examples. Compilers could be better, with more warnings when they detect mistakes (though it is extremely difficult to warn on "code removed due to UB assumptions" without a lot of false positives). Compilers could have better defaults - perhaps if gcc is invoked without "-Wall", it should print a large banner message suggesting that the user RTFM and enable warnings. Tool vendors could make better static error checking, and more runtime check options (like sanitizers). Developers could get a /lot/ better at using the tools that already exist. Developers could think more about the code they are writing. Developers could do better at making sure their code is /really/ correct - not just adding comments so that it appears to be correct. Developers could be better at using other languages when other languages are more suitable for the task in hand. Developers could do better at making use of newer C standards, and if appropriate, compiler extensions. And people commenting on how terrible C and C compilers are could think a little about the vast amount of C code that is written that does not contain such bugs, and the vast amount of bugs in code written in different languages. Buggy code is not a C issue.

I don't see it as a horror story. Maybe a cautionary tale. None of the examples are what I would call hard to understand, or difficult to remedy.

Division by 0 is UB, so compilers can happily reduce "a * n / n" to "a"
even if "n" might be 0.
If a particular platform guarantees some kind of signal or hardware
exception on division by 0, then it's a different matter. But that's
because the implementation has given semantics to that particular UB,
not because it is required by the language.
(Similarly, an implementation could specify that dereferencing a null
pointer is fine because 0 is a normal memory address, or that it is
guaranteed to trigger an OS-determined signal or fault - then despite
being UB in the C standards, dereferencing a null pointer would be
defined on that implementation.)

Not in C. Evaluation of "a * 0 / 0" is UB, so reading "a" meets the

I am not sure what "such reasons" really are. I would say that if
results of wrong program change under small variations (say using
different compiler options), then this is good things, as this
makes finding bugs easier.

I think that arithmetic should generally stay within its environmental bounds, or else, ideally, an error/signal/etc. should be triggered. And I think that it's the programmers' task to guarantee that (and not rely on any assumptions). - Needless to say, it had never been a problem to guarantee that, either inherently or by taking appropriate precautions where necessary. (Including programming in "C".) For modular arithmetic within the arithmetic limits an explicit modulus should be written; that can and will be optimized away by the compiler if necessary; especially for the few trivial types-lengths constants). > [...] > > And fortunately I mostly use alternative languages where that UB does > not exist; I don't need to worry about it, and I can have 100% > confidence in the behaviour. I think this is a problematic view; since you cannot guarantee that a language will (or can) define "everything" you like (see below). I've looked over a couple languages that I used over the past decades. Most were having no special technical term of "UB", but they often just didn't define what will happen in such cases, or they *informally* say that "it's undefined". Some do explicitly note that you have to _stay_ _within_ the arithmetic bounds, some support means to interrogate the environmental limits even dynamically. Some say that "usually" an error will be triggered. And so on. For good measure I suggest to just stay within the environmental bounds or choose appropriate types if you want to model modulus types (residue class rings). For the "C" case and contemporary system platforms I cannot tell; but I faintly recall systems that support _hardware exception triggers_ on overflows. But I'm unsure about whether you could somehow disable that behavior from the "software-level". Other systems don't support these triggers. So what shall a language (as opposed to a concrete platform) [for the general case] define here? Janis

The Burroughs medium systems languages supported a mechanism for the application programmer to interrogate the overflow condition after any arithmetic operation. In COBOL, an ON OVERFLOW condition (or IF OVERFLOW statement) would follow the COMPUTE (or other arithmetic expression) verb. Other languages (BPL, SPRITE) supported similar syntax. Most modern CPUs will set an overflow flag when the result of a calculation cannot be represented within the bounds of the result datum. C could, I suppose, have an extension to expose the 'overflow' flag to the programmer.

A C implementation certainly could, though you'd want to define
(or leave undefined) the decision of which operation you're checking.
But not all CPUs indicate overflow by setting a flag. Probably most
or all CPUs can detect overflow, but exposing that in C is tricky.

I have seen embedded compilers that expose compiler flags via intrinsics.
But accessing flags from C would have all kinds of complications at the
hardware level :
First, some processors do not have flags or flag registers.
Some have multiple flag registers.
Different processors have different choices of flags.
Many processors have alternative instruction forms that distinguish
between setting flags or ignoring them. (Setting flags can often
significantly hinder superscaling and cause pipeline stalls.)
From a higher level, it could also greatly complicate the semantics of
the language and hinder optimisation. If an overflow or carry flag were
visible from C, an operator like "+" would no longer be defined to give
the sum of its operands. It would have to be defined to affect a hidden
thread-local boolean variable "overflow" as well. And now evaluating "x
+ y + z" is writing to this flag twice without defined sequencing - it's
UB. So now "+" would have to introduce a sequence point, and force the
order of evaluation. All sorts of optimisations from re-arrangements of
expressions would be crippled.
A far better solution, IMHO, would be to have a header with a types like
"struct flagged_uint32_t { bool overflow; uint32_t value; }" and with
operation macros/functions on these. Then you have something clear and
specific, that fits with existing C, without messing up the language
completely. Compilers could implement these types and operations
efficiently using the processor's flags (for local variables at least).
Or we could just use chk_add() and friends :-)

In practice, things work as expected if you write correct code that does not hit UB. If you /do/ hit UB, all bets are off. In meaningless little test cases, you can often get the results that /you/ expect. But unless you only ever intend to write meaningless little test cases, that is not helpful knowledge. You are extrapolating from almost no evidence for your claims. > > So, doing a * b is UB when it overflows, and that is very important > because bad things can happen. But nobody can tell me what. Or good things can happen - you get better code when there is not an overflow. Nobody can tell you what happens in UB, because there are no limits to what can happen with UB. Usually compilers generate code that is either more efficient (by ignoring the overflow, or eliminating other code because they assume UB does not happen), or they generate code that is the same as wrapping behaviour because that's the most efficient on most processors. But it is all totally dependent on the rest of the code, and the compiler. Your fundamental problem here seems to be that you think there should be an answer to "what happens when there is UB?", when the whole meaning of UB is that there is /no/ answer. > > But then an implementation can decide to make well-defined.

How do I find out if that's the case? > You find out by reading the compiler's documentation. gcc, for example, documents that with the "-fwrapv" flag, signed overflow has wrapping semantics. So if you want to get these semantics, you can do so with "gcc -fwrapv". If you are happy with that, and stick to that compiler and flag, then UB on signed overflow no longer matters to /you/. It is still relevant to everyone else programming in C. I have read countless C compiler manuals over the decades, and I have not seen any other that specifically says they give signed arithmetic wrapping semantics (or any other defined semantics). (I've seen a few that specifically note it as UB.) So I think it is rare for compilers to guarantee this kind of behaviour. And since the C standards are clear that it is UB, I would not assume any compiler would define the semantics unless the compiler's documentation said so explicitly. A couple of little tests is in no way sufficient. > Or I can use -fwrapv, and... that makes the UB go away?

What else would you expect for /documented/ behaviour? If they compile it without that option, and the calculation overflows, you should not have any expectations. > Then, UB is actually a good thing, because it enables all these > optimisations, but when I try them with gcc-O3, they don't work because > some made them up!

But given that it is almost always very simple to write code where your integer arithmetic does not overflow, and wrapped answers are almost always wrong, it seems rather ridiculous to stick your fingers in your ears and pretend that it's fine to overflow your arithmetic. > > And fortunately I mostly use alternative languages where that UB does > not exist; I don't need to worry about it, and I can have 100% > confidence in the behaviour. > If you like.

That's because it's undefined behavior. If someone could tell you what would happen, it would be defined behavior. For instance, the C standard could impose defined behavior for integer division by 0. It could mandate that such a division must result in the computer halting and catching fire. That would not be undefined behavior. This could even be useful, if for any reason you actually want to set fire to the computer. Unfortunately, that would make the C standard unimplementable on most platforms. When the behavior is undefined, the C standard imposes no restrictions on what behavior is permitted. Therefore, if there is anything, absolutely anything, that your computer could be instructed to do, and that you don't want it to do - the standard permits a conforming implementation to generate code that would make it do that. It could also generate code to do something else entirely. If you are quite certain that the implementation won't take advantage of that fact, you're fine. However, I'm not sure how you could justify such certainty. If that uncertainty doesn't bother you, go ahead!
