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.

Basically, the paper says :

Sometimes people don't understand the details of the semantics of the 
language they are using.  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.

I could agree that folks, depending on their character, can react
differently on that paper. Unless paralyzed, threatened, or fleeing,
keeping a cool head and being cautionary is certainly advisable in
that territory.

Yes.  Also, in my case at least part of my calmness came from having
seen cases with surprising consequences before.

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).

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?

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.

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.

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.

If they compile with "gcc -fwrapv", then the result of overflow is 
wrapped behaviour.  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.

I can't figure out what you are trying to say here, sorry.

It is irrelevant for judging the general effect of -ftrapv, or 
optimisations based on signed overflow being UB.  At best, you have only 
got an idea for your example code.

You are not the first person to write code with the "correct by luck" 
and "it worked when I tested it on my machine" strategy.  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.

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!
