gdb/Testsuite/Changelog:
* gdb.fortran/vla-value.exp: Use type names defined in libfortran.
* gdb.mi/mi-var-child-f.exp: Likewise.
* gdb.mi/mi-vla-fortran.exp: Likewise.

Before continuing with language specific type printing
we have to resolve the target type of a pointer
as we might wanna print more details of the target
like the dimension of an array. We have to resolve it here
as we don't have any address information later on.
2016-07-08 Bernhard Heckel <bernhard.heckel@intel.com>
gdb/Changelog:
* typeprint.c (whatis_exp): Resolve dynamic target type
of pointers.
gdb/Testsuite/Changelog:
* gdb.cp/vla-cxx.cc: Added pointer to dynamic type.
* gdb.cp/vla-cxx.exp: Test pointer to dynamic type.

Show the type of not-allocated and/or not-associated types
as this is known. For array types and pointer to array types
we are going to print the number of ranks.
2016-06-30 Bernhard Heckel <bernhard.heckel@intel.com>
gdb/ChangeLog:
* f-typeprint.c (f_print_type): Don't bypass dangling types.
(f_type_print_varspec_suffix): Add print_rank parameter.
(f_type_print_varspec_suffix): 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.
* gdb.fortran/print_type.exp: New.
* 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.

Addressed in V4:
- Fix indentation in f-typeprint.
Addressed in V3:
- Don't resolve target types of pointers when resolving pointer types.
- Address pointers to dynamic types in C99 as well.
- Resolve dynamic target types of pointers when actual needed.
- Fix some type naming in Fortran testcases.
Addressed in V2:
- The type of the pointer should be known regardless it is
associated with target or not, [PATCH V2 1/5].
- Removed [PATCH V1 1/3], moved tests to [PATCH V2 2/5].
- Added tests to print derefenced pointers, [PATCH V2 2/5].
- Fix address print of not allocated arrays/pointer to
not allocated types, [PATCH V2 4/5]
Bernhard Heckel (6):
Fortran: Testsuite, fix differences in type naming.
Fortran: Resolve dynamic properties of pointer types.
Typeprint: Resolve any dynamic target type of a pointer.
Fortran: Typeprint, fix dangling types.
Resolve dynamic target types of pointers.
Fortran: Testsuite, add cyclic pointers.

Do we already have a test case which has a Fortran pointer which has
a dynamic associated property? If no, we need to add one.
Patch 3/6 resolves dynamic target type of a pointer, a pointer points
to a dynamic type, but what does this patch do?

Yes, we have a testcase already.
vla-ptype.exp + vla.f90
This testcase was already passing as gfortran describes a pointer to an
array as an array + associated property.
For Ifort, a pointer in the program is still a pointer type in the debug
info.

The patch only resolves the "associated property" of a pointer.
According to Joel review (some time ago), I only resolve target types of
pointer when we actually have to (see following patches in this series).
I wanted to keep this patch separate from resolving dynamic target
types, as this patch is independent from those but not vice verse.

is_dynamic_type returns bool-like value, so don't check it with 1.
Looks we need to check is_dynamic_type (TYPE_TARGET_TYPE (type)), no?

is_dynamic_type takes care of target types for pointer and reference types.
So, we can keep it.

Why do we need to different regex here? Need to handle the differences
of different compilers? IMO, the former looks reasonable to me.

Again, different outputs due to different compilers? The latter looks
reasonable to me.

A pointer to an array (especially to Variable Length Array, VLA) is
described in Gfortran's compiled debug info
like normal array types + associated property of an pointer.
Not sure if this is a bug in Gfortran or not? I was also thinking to
make the
output equal, and check if an array has pointer attributes but ..... I
don't really like this approach. This would
cause a lot of "if .. else" construct in the code for example:
De-reference this pointer, Address operator, ...

I we keep this, we shortcut any additional printing of the target type
of a pointer in case it is not associated.

Could you show the debug information gfortran and ifort generates
respectively?

If gfortran people confirm it is a bug, we can xfail the test.

I just looked again in the specification. It is not a bug.
FORTRAN specification (http://www.j3-fortran.org/doc/year/04/04-007.pdf)

In "Glossary of technical terms", array pointer (5.1.2.5.3) : A pointer to an
array, so it is a pointer, not an array.
In your example,
integer, pointer, dimension (:) :: intvlap

I fear it take some time.
There is one more patch series which handles "variable length strings"
and the series depends on the pointer feature.
It would be nice to move on, as the "variable length string"
implementation is the last
piece which is missing to complete the VLA feature set.

DWARF4 gives an implementation proposal of array pointers and it is like
Gfortran is
implementing it.
-> See D.2 Aggregate Examples

So, Gfortran is ok here.
