Fortran: improve compile-time checking of character dummy arguments [PR93330]
PR fortran/93330
gcc/fortran/ChangeLog:
* interface.cc (get_sym_storage_size): Add argument size_known to
indicate that the storage size could be successfully determined.
(get_expr_storage_size): Likewise.
(gfc_compare_actual_formal): Use them to handle zero-sized dummy
and actual arguments.
If a character formal argument has the pointer or allocatable
attribute, or is an array that is not assumed or explicit size,
we generate an error by default unless -std=legacy is specified,
which falls back to just giving a warning.
If -Wcharacter-truncation is given, warn on a character actual
argument longer than the dummy. Generate an error for too short
scalar character arguments if -std=f* is given instead of just a
warning.
gcc/testsuite/ChangeLog:
* gfortran.dg/argument_checking_15.f90: Adjust dg-pattern.
* gfortran.dg/bounds_check_strlen_7.f90: Add dg-pattern.
* gfortran.dg/char_length_3.f90: Adjust options.
* gfortran.dg/whole_file_24.f90: Add dg-pattern.
* gfortran.dg/whole_file_29.f90: Likewise.
* gfortran.dg/argument_checking_27.f90: New test.
