Show the type of not-allocated and/or not-associated types. For array
types and pointer to array types we are going to print the number of
ranks.
Consider this Fortran program:
program test
integer, allocatable :: vla (:)
logical l
allocate (vla(5:12))
l = allocated (vla)
end program test
And this GDB session with current HEAD:
(gdb) start
...
2 integer, allocatable :: vla (:)
(gdb) n
4 allocate (vla(5:12))
(gdb) ptype vla
type = <not allocated>
(gdb) p vla
$1 = <not allocated>
(gdb)
And the same session with this patch applied:
(gdb) start
...
2 integer, allocatable :: vla (:)
(gdb) n
4 allocate (vla(5:12))
(gdb) ptype vla
type = integer(kind=4), allocatable (:)
(gdb) p vla
$1 = <not allocated>
(gdb)
The type of 'vla' is now printed correctly, while the value itself
still shows as '<not allocated>'. How GDB prints the type of
associated pointers has changed in a similar way.
gdb/ChangeLog:
* f-typeprint.c (f_print_type): Don't return early for not
associated or not allocated types.
(f_type_print_varspec_suffix): Add print_rank parameter and print
ranks of array types in case they dangling.
(f_type_print_base): Add print_rank parameter.
gdb/testsuite/ChangeLog:
* gdb.fortran/pointers.f90: New file.
* gdb.fortran/print_type.exp: New file.
* gdb.fortran/vla-ptype.exp: Adapt expected results.
* gdb.fortran/vla-type.exp: Likewise.
* gdb.fortran/vla-value.exp: Likewise.
* gdb.mi/mi-vla-fortran.exp: Likewise.
