Good question.


There is a sort of partial ordering (or lattice order) of behaviour 
specifications.  "undefined behaviour" is at the bottom - it implements 
nothing, and anything else can implement it.  "implementation-defined" 
is stronger.  If the standards say "UB", then an implementation can 
define behaviour more concretely.  If the standards say "IB", then the 
implementation cannot turn it into "UB".  So "UB" in the standards 
clearly gives the most flexibility to the implementation.

The big disadvantage of making something like this "IB" is not that the 
compiler implementers need to document their handling, but that they 
need to have a specification for it and stick to that - users must be 
able to rely on IB being consistent.  Different types of handling for 
hitting "unreachable()" can include compiler optimisation on the 
assumption that it is never reached, generating a target "trap" 
instruction, generating a "breakpoint" when debugging, printing out an 
error message and terminating, calling a user-defined function that 
sends an angry email to the developer, and tracking all possible code 
flows at build time and giving a compiler warning if it can, in fact, be 
reached.  Some users will prefer one method, others will prefer a 
different one, and many will change depending on what they are doing. 
Crucially, compilers may change what they support over time.  A compiler 
cannot document "IB" as "depending on flags, this might be treated as 
UB, or give a trap, or perhaps do something else in the future".  But it 
/can/ do exactly that if the standards say it is "UB".

It is also important to note that gcc, clang, icc, and many other 
compilers have had something like this for decades - like 
__builtin_unreachable() - which are implemented exactly as "undefined 
behaviour" in these tools.


This is, as far as I can tell, the proposal paper that led to 
"unreachable()" being added to the C standards:

<https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2826.pdf>

"""
We propose the feature unreachable to specify branches in the control 
flow of a program that will never be reached. The aim is to provide means 
for the user to express guarantees about the effective control flow that
will be executed by a program. Compilers may then apply aggressive 
optimizations that otherwise would not be possibly or that would rely on 
the detection of undefined behavior for certain input combinations.
"""

The C++ version is :

<https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p0627r6.pdf>

The discussion about the definition is :

"""
What is the best way to define the attribute's effect? The author feels 
that the best way is to make the behavior of std::unreachable() be 
undefined. There are several reasons:

* std::unreachable() causing undefined behavior means that the Standard 
would not prescribe any particular action, leaving open many possible 
implementation actions.

* Some compilers already associate being unreachable to undefined 
behavior. Clang’s documentation states that __builtin_unreachable() “has 
completely undefined behavior”.

* Optimizing under the assumption that a statement is unreachable, and 
thus having unpredictable behavior if the statement is in fact 
reachable, falls naturally under "undefined behavior".

* An alternative would be to issue a trap if std::unreachable() is 
executed. This could be used in "debug builds", for example. Such a trap 
falls under "undefined behavior".

* Being undefined behavior implies what happens if a constexpr function 
calls std::unreachable(): it's not a constant-expression, by (N4713) 
[expr.const]/2.6

In the author’s opinion, it is not undefined behavior itself that is the 
problem, but rather unexpected undefined behavior. C++ will always have 
undefined behavior; this is unavoidable. Situations in which undefined 
behavior occurs unexpectedly are problematic for programmers, because 
they often lead to subtle bugs, or unexpected compiler optimizations. 
However, std::unreachable() is expected undefined behavior: a programmer 
using it knows that undefined behavior will occur there and is making
a calculated risk in using it.
