program struct
REAL , POINTER :: RD(:,:) =>NULL()
ALLOCATE(RD(10,10))
Compile with gfortran -g struct.f90
The Dwarf output for RD leads to:
<1><10d>: Abbrev Number: 5 (DW_TAG_pointer_type)
DW_AT_byte_size : 4
-- there should be a type in there (there is with most other compilers..) --
otherwise we have to interpret RD as Void* instead of double*.

Works for me. Can you check with a recent 4.4 compiler? There I get:
(idb) pt RD
type = REAL(4)(10)(10)
which looks OK.

With gdb on i686-apple-darwin9, I get either
(gdb) pt rd
type = real*4 (0:-1,0:-1)
or
(gdb) pt rd
No symbol "rd" in current context.

------- Comment #4 from burnus at gcc dot gnu dot org 2008-10-11 16:32 -------
Jakub, I think GCC sets the wrong type for "rd". It has:
<1><1bb>: Abbrev Number: 7 (DW_TAG_array_type)
<1bc> DW_AT_name : (indirect string, offset: 0xf9): array2_real(kind=4)
whereas for ifort I get:
<1><1fc>: Abbrev Number: 5 (DW_TAG_pointer_type)
<1fd> DW_AT_type : <0x207>
<201> DW_AT_associated : 5 byte block: 97 6 10 0 2e
(DW_OP_push_object_address; DW_OP_deref; DW_OP_constu: 0; DW_OP_ne)
<1><207>: Abbrev Number: 6 (DW_TAG_array_type)
The DW_TAG_pointer_type and the DW_AT_associated should be there; gfortran has
DW_AT_allocated which should not be there as there is no allocatable variable.
Or do I miss something? My DWARF knowledge is limited.
(In reply to comment #3)
> With gdb on i686-apple-darwin9, I get either
You know that gdb does not yet support variable-length arrays such as Fortran's
assumed-shape arrays and C's (or was it C++'s?) VLA? This is work in progress
(thanks, Jan!), see:
http://sourceware.org/ml/gdb-patches/2008-10/msg00248.html
http://people.redhat.com/jkratoch/vla/
Thus I was testing with the Intel Debugger (idb).

Has this been WAITING for 18 months now?
Any news? :)

------- Comment #6 from jakub at gcc dot gnu dot org 2010-04-30 21:34 -------
It IMHO shouldn't be DW_TAG_pointer_type, it is not a C style pointer.
DW_TAG_array_type is what is emitted and what is listed in DWARF3/4 examples
for Fortran code with POINTER variables. And current GCC certainly emits
DW_AT_associated rather than DW_AT_allocated for POINTER vars.
So I don't see any problem on the gfortran producer side.

I take this as a suggestion to close this PR.
Please reopen if misinterpreted.
