            Bug ID: 112609
           Summary: [F2023] Restrictions on integer arguments to
                    SYSTEM_CLOCK
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: anlauf at gcc dot gnu.org
  Target Milestone: ---

F2023 has changed the requirements for the arguments to SYSTEM_CLOCK:

"Fortran 2018 allowed integer arguments to the intrinsic subroutine
SYSTEM_CLOCK to be of any kind. This document requires integer arguments to
SYSTEM_CLOCK to have a decimal exponent range at least as large as a default
integer, and requires that all integer arguments in a reference to
SYSTEM_CLOCK have the same kind type parameter."

    Fortran: restrictions on integer arguments to SYSTEM_CLOCK [PR112609]

    Fortran 2023 added restrictions on integer arguments to SYSTEM_CLOCK to
    have a decimal exponent range at least as large as a default integer,
    and that all integer arguments have the same kind type parameter.

    gcc/fortran/ChangeLog:

            PR fortran/112609
            * check.cc (gfc_check_system_clock): Add checks on integer
arguments
            to SYSTEM_CLOCK specific to F2023.
            * error.cc (notify_std_msg): Adjust to handle new features added
            in F2023.
            * gfortran.texi (_gfortran_set_options): Document
GFC_STD_F2023_DEL,
            remove obsolete option GFC_STD_F2008_TS and fix enumeration values.
            * libgfortran.h (GFC_STD_F2023_DEL): Add and use in
GFC_STD_OPT_F23.
            * options.cc (set_default_std_flags): Add GFC_STD_F2023_DEL.

    gcc/testsuite/ChangeLog:

            PR fortran/112609
            * gfortran.dg/system_clock_1.f90: Add option -std=f2003.
            * gfortran.dg/system_clock_3.f08: Add option -std=f2008.
            * gfortran.dg/system_clock_4.f90: New test.
