--- Comment #5 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
You cannot use this internal macro to deduce how your C testcase should behave.
The language standard says this conversion has implementation-defined behavior,
and GCC manual (the user manual, not the internals manual) has a chapter on
implementation-defined behavior, which explicitly says:
https://gcc.gnu.org/onlinedocs/gcc/Arrays-and-pointers-implementation.html
A cast from pointer to integer [...] sign-extends if the pointer representation
is smaller than the integer type [...].
So the behavior is the same for all targets.
