Hi Yuao,
thanks for your patch. I have two nits:
* There is no diagnostic for -std=f2018 (or lower);
can you add the 'gfc_notify_std (GFC_STD_F2023' ?
* I have a minor documentation nit; current wording is
at https://gcc.gnu.org/onlinedocs/gfortran/C_005fF_005fPOINTER.html
Namely, ...

I think some wording like the following is missing:
"For an array @var{FPTR}, the lower bounds are specified by @var{LOWER} if present
and otherwise equal to 1."

I think we should append ", with @var{LOWER} argument Fortran 2023 and

Otherwise, it looks good to me. Thanks for your GCC contributions!

PS: Eventually, we should update https://gcc.gnu.org/gcc-16/changes.html
for the accumulated Fortran changes … [That's the
