[PATCH 10/23] vla: get Fortran dynamic strings working.

[PATCH 10/23] vla: get Fortran dynamic strings working.

[Keven Boell]

This patch enables the correct calculation of dynamic
string length.

Old:
(gdb) p my_dyn_string
$1 = (PTR TO -> ( character*23959136 )) 0x605fc0

(gdb) p *my_dyn_string
Cannot access memory at address 0x605fc0

New:
(gdb) p my_dyn_string
$1 = (PTR TO -> ( character*10 )) 0x605fc0

(gdb) p *my_dyn_string
$2 = 'foo'

2014-05-28  Keven Boell  <keven.boell@intel.com>
            Sanimir Agovic  <sanimir.agovic@intel.com>

	* gdbtypes.c (resolve_dynamic_type): Add
	conditions to support string types.
	(resolve_dynamic_array): Add conditions for dynamic
	strings and create a new string type.
	(is_dynamic_type): Follow pointer if a string type
	was detected, as Fortran strings are represented
	as pointers to strings internally.

[PATCH 05/23] vla: make field selection work with vla

[Keven Boell]

In Fortran vla are pointers to arrays. Thus a
type only contains a pointer to such array and
we need to re-read the field to retrieve the
correct vla.

old (wrong value):
(gdb) p type_var%vla(14)
$1 = 1

new (correct value):
(gdb) p type_var%vla(14)
$1 = 42

	* value.c (value_primitive_field): Re-evaluate

[PATCH 06/23] vla: reconstruct value to compute bounds of target type

[Keven Boell]

Printing a pointer to an array, gdb tries to print the
target type including its bounds. To follow this
semantic with vla, this patch re-constructs the value to
resolve the bounds of the target type.

2014-05-28  Sanimir Agovic  <sanimir.agovic@intel.com>
            Keven Boell  <keven.boell@intel.com>

	* typeprint.c (whatis_exp): Re-construct value to
	compute bounds of target type.
	* c-valprint.c (c_value_print): Re-construct value
	to compute bounds of target type.

[PATCH 08/23] vla: get dynamic array corner cases to work

[Keven Boell]

This patch does not overwrite the value type in
case it is a dynamic type. For dynamic types GDB
resolved its dynamic values in a copy of the type.
The call to deprecated_set_value_type overwrites the
resolved type with the original type, which breaks
e.g. pointer to a Fortran type, which contains a dynamic
array.

Old:
(gdb) print &vla1
(PTR TO -> ( real(kind=4) (23959136:23959184))) 0x7fffffffd490

New:
(gdb) print &vla1
(PTR TO -> ( real(kind=4) (5))) 0x7fffffffd490

[PATCH 00/23] Fortran dynamic array support

[Keven Boell]

This patch series add Fortran dynamic array support to gdb.

It allows the user to evaluate a dynamic array like an ordinary static array
e.g. print its elements instead of printing the pointer to the array.
In addition the size of a dynamic array can be retrieved with gdbs builtin
sizeof operator. Furthermore this series add support for Fortran stride support.

	1| integer, allocatable :: ary(:)
	2| allocate(ary(5))
	3| ary(:) = 42

	(gdb) print ary
	$1 = (42, 42, 42, 42, 42)

	(gdb) print sizeof (ary)
	$2 = 20

	(gdb) ptype ary
	type = integer(kind=4) (5)

This series is a follow up for the following C99 variable length array
support series:
	https://sourceware.org/ml/gdb-patches/2013-12/msg00625.html

[PATCH 07/23] vla: use value constructor instead of raw-buffer manipulation

[Keven Boell]

Instead of pre-computing indices into a fortran array re-use
the value_* interfaces to subscript a fortran array.

2014-05-28  Sanimir Agovic  <sanimir.agovic@intel.com>
            Keven Boell  <keven.boell@intel.com>

	* f-valprint.c (f77_create_arrayprint_offset_tbl): Remove
	function.
	(F77_DIM_SIZE, F77_DIM_OFFSET): Remove macro.
	(f77_print_array_1): Use value_subscript to subscript a
	value array.
	(f77_print_array): Remove call to f77_create_arrayprint_offset_tbl.
	(f_val_print): Use value_field to construct a field value.

[PATCH 03/23] vla: introduce allocated/associated flags

[Keven Boell]

Fortran 90 provide types whose values may be dynamically
allocated or associated with a variable under explicit
program control. The purpose of this commit is to read
allocated/associated DWARF tags and store them to the
main_type.

2014-05-28  Keven Boell  <keven.boell@intel.com>
            Sanimir Agovic  <sanimir.agovic@intel.com>

	* dwarf2read.c (set_die_type): Add reading of
	allocated/associated flags.
	* gdbtypes.h (struct main_type): Add allocated/
	associated dwarf2_prop attributes.
	(TYPE_ALLOCATED_PROP): New macro.
	(TYPE_ASSOCIATED_PROP): New macro.
	(TYPE_NOT_ALLOCATED): New macro.
	(TYPE_NOT_ASSOCIATED): New macro.

[PATCH 04/23] vla: make dynamic fortran arrays functional.

[Keven Boell]

This patch enables GDB to print the value of a dynamic
array (VLA) if allocated/associated in fortran. If not the
allocation status will be printed to the command line.

(gdb) p vla_not_allocated
$1 = <not allocated>

(gdb) p vla_allocated
$1 = (1, 2, 3)

(gdb) p vla_not_associated
$1 = <not associated>

(gdb) p vla_associated
$1 = (3, 2, 1)

The patch covers various locations where the allocation/
association status makes sense to print.

2014-05-28  Keven Boell  <keven.boell@intel.com>
            Sanimir Agovic  <sanimir.agovic@intel.com>

	* dwarf2loc.c (dwarf2_address_data_valid): New
	function.
	* dwarf2loc.h (dwarf2_address_data_valid): New
	function.
	* f-typeprint.c (f_print_type): Print allocation/
	association status.
	(f_type_print_varspec_suffix): Print allocation/
	association status for &-operator usages.
	* gdbtypes.c (create_array_type_with_stride): Add
	query for valid data location.
	(is_dynamic_type): Extend dynamic type detection
	with allocated/associated. Add type detection for
	fields.
	(resolve_dynamic_range): Copy type before resolving
	it as dynamic attributes need to be preserved.
	(resolve_dynamic_array): Copy type before resolving
	it as dynamic attributes need to be preserved. Add
	resolving of allocated/associated attributes.
	(resolve_dynamic_type): Add call to nested
	type resolving.
	(copy_type_recursive): Add allocated/associated
	attributes to be copied.
	(copy_type): Copy allocated/associated/data_location
	as well as the fields structure if available.
	(resolve_dynamic_compound): New function.
	* valarith.c (value_subscripted_rvalue): Print allocated/
	associated status when indexing a VLA.
	* valprint.c (valprint_check_validity): Print allocated/
	associated status.
	(val_print_not_allocated): New function.
	(val_print_not_associated): New function.
	* valprint.h (val_print_not_allocated): New function.
	(val_print_not_associated): New function.
	* value.c (set_value_component_location): Adjust the value
	address for single value prints.

[PATCH 02/23] dwarf: add DW_AT_data_location support

[Keven Boell]

An object might have a descriptor proceeding the actual value.
To point the debugger to the actually value of an object
DW_AT_data_location is used for. For example the compile may
emit for this entity:

  1| int foo[N];

the following descriptor:

struct array {
  size_t size;
  void*  data; // DW_AT_data_location describes this location
}

This allows GDB to print the actual data of an type.

2014-05-28  Sanimir Agovic  <sanimir.agovic@intel.com>
            Keven Boell  <keven.boell@intel.com>

	* dwarf2read.c (set_die_type): Parse and save DW_AT_data_location
	attribute.
	* gdbtypes.c (is_dynamic_type): Consider a type being dynamic if
	the data location has not yet been resolved.
	(resolve_dynamic_type): Evaluate data location baton
	if present and save its value.
	* gdbtypes.h <main_type>: Add data_location.
	(TYPE_DATA_LOCATION): New macro.
	(TYPE_DATA_LOCATION_ADDR): New macro.
	(TYPE_DATA_LOCATION_IS_ADDRESS): New macro.
	* value.c: Include dwarf2loc.h.
	(value_fetch_lazy): Use data location addres to read value from
	memory.
	(coerce_ref): Construct new value from data location.

[PATCH 09/23] vla: changed string length semantic.

[Keven Boell]

This patch changes the semantic of the Dwarf string length
attribute to reflect the standard. This serves as pre-work
to get variable strings in Fortran to work.

2014-05-28  Keven Boell  <keven.boell@intel.com>
            Sanimir Agovic  <sanimir.agovic@intel.com>

	* dwarf2read.c (read_tag_string_type): changed
	semantic of DW_AT_string_length to be able to
	handle Dwarf blocks as well. Support for
	DW_AT_byte_length added to get correct length
	if specified in combination with
	DW_AT_string_length.
	(attr_to_dynamic_prop): added
	functionality to add Dwarf operators to baton
	data attribute. Added post values to baton
	as required by the string evaluation case.
	(read_subrange_type): Adapt caller.
	(set_die_type): Adapt caller.
	(add_post_values_to_baton): New function.
	* dwarf2loc.c (dwarf2_evaluate_property): Evaluate
	post processing dwarf.
	* dwarf2loc.h (struct dwarf2_property_baton): Add
	post dwarf values attribute.

This looks good.

However, normally if one updates the DWARF expression evaluator, one
should either try to update the DWARF->AX translator in dwarf2loc.c, or
provide some rationale explaining why it either can't be done or is
otherwise undesirable.  In this case I think the translation seems
doable.  See dwarf2_compile_expr_to_ax.  There's also
dwarf2read.c:decode_locdesc, but it is hackier and more likely to be
ignorable.

Some comments and questions below...

My main question is relative to the new "addr" field. In many cases,
inferior data is not referenced by address, but via  "struct value"
objects. And such objects are not necessarily addressable (Eg: they
live inside a register, or are broken down into pieces, etc).
I am wondering how things are going to be working in this case,
and in particular, for a code that have a struct value object,
and tries to resolve its type into a static type, how does it
provide an address, knowning that it does not always exist? Perhaps
we can make the assumption for such complex objects that when
a DW_OP_push_object_address is used, the object is always assumed
to be addressable? Whatever the answer is, I think it's worth
documentation clearly what the expectations are.  Also, it's interesting
to note that several callers currently pass 0 as the (unused) address,
but will eventually need to be update to pass the correct info.

> +/* DW_OP_push_object_address has a frame already passed thru.  */
                                                           ^^^^
Sorry to nit-pick on this one, but I'd rather we spelled words
correctly.

I just noticed that this function was missing a short description
(my bad), so I added it. Would you mind amending this patch to
update the description and add the meaning of ADDR?

Here are some comments and questions, but it would be nice,  IMO, if
the patch was also reviewed by Tom, particularly since it introduces
a new field in struct main_type, which is a size-sensitive, I think.

Also, it would be nice if you could include a copy of the actual
DWARF output in the revision log of your patch, for easy reference
of what you're trying to support.

Here (in set_die_type), why do you limit the processing the block-form
data_location attributes? Why not just call attr_to_dynamic_prop
regardless of the form, and let that function deal with whatever
the form is? In other words, trop the form check and just keep
the following bit:

The comment needs to be updated. Your change is also splitting
the "if bounds or contents is dynamic" logic. Perhaps you could
simply add the data-location check at the start of the function
with a command that says: A type which has a data_location which
[bla bla] is a dynamic type

Here, I do not understand why you override TYPE, instead of just
using RESOLVED_TYPE directly.

I'd like to have a comment which is a little more descriptive of
what this field contains. Someone who reads this comment should be
able to understand it without having to grep for this field to
get an idea of how this field is used.

I think this comment is too specific. Although this field is
instroduced to support VLAs, descriptors can probably be used
in other contexts. I don't think you really need a comment,
in this case, though.

I am wondering if this part shouldn't be in value_address itself.

Re: [PATCH 01/23] dwarf: add dwarf3 DW_OP_push_object_address opcode

[Keven Boell]

Hi Joel,

The address fields were introduced as DW_OP_push_object_address
needs an object address to be pushed and this address needs to be stored
somewhere. However, I will extend the log message why this address fields
were introduced.

I've addressed all your other comments and will send out 
a version 2 of the patch series soon, because some rebasing 
had to be done anyway.

Re: [PATCH 01/23] dwarf: add dwarf3 DW_OP_push_object_address opcode

[Keven Boell]

Hi Tom,

I will set it to unimplemented for now like DW_OP_GNU_push_tls_address in the AX 
part as I think this is a project by its own to implement such support here.
One needs to have more information for resolving a VLA's
address using DW_OP_push_object_address as the dwarf2_compile_expr_to_ax
and the callers of it seems to only have the variable location, which
isn't enough as one needs the data location, the bounds and the stride
to correctly resolve the address.

I understand this part, but the main part of my question is about
the fact that, most of the time, we manipulate "struct value" objects,
which may not represent addressable entities. For instance, let's say
I have a struct value whose type is a TYPE_CODE_ARRAY. If I need to
resolve the value's type, how should I be doing it? Perhaps, the
question in itself suggest the introduction of a function that would
take a value, and returned a value whose time is resolved?

But this would still require the address to be communicated to the
property evaluation functions as the type still needs to be resolved
using resolve_dynamic_type. Usually resolve_dynamic_type will be called
through value_from_contents_and_address, which generates you a resolve
type in a value object. Do you have a concrete Fortran code example,
where you think the current implementation might go wrong?

I think we're talking past each other :-(, so I'll try to explain
in more details what I have in mind.

I do not have any concrete Fortran example for you, and I am not
saying that the implementation is wrong. I am asking a question
of how things should work if the object you are trying to evaluate
and resolve actually does not live in memory. If the object does
not live in memory (eg: lives in register), are we stuck? The answer
might be yes, or maybe that's something that can't happen, but I would
like to explore that question to have a better understanding of what
we can expect to achieve.

Ideally, I have a feeling that what we should be taking isn't
an address, but a struct value.  The struct value object carries
much more information, and might allow us to deal with the case
above. Another interesting, and perhaps more likely scenario, is
the case where part of the object is optimized out. You can't
expect a "contents and address" to represent accurately your object,
so chances are GDB would get it wrong.

And the concrete situation that triggered all these questions
is code in ada-lang.c. Take for instance ada_array_bound, which
takes an unresolved array as a struct value (ARR), and returns
the lower/higher bound for the nth dimension:

    ada_array_bound (struct value *arr, int n, int which)

The function essentially finds ARR's N'th index type and calls
resolve_dynamic_type on that type. If you actually look at
the code, it's slightly indirect, but it's the idea.

    ada_array_bound
      -> ada_array_bound_from_type
           -> ada_discrete_type_high_bound
                -> resolve_dynamic_type

Now, what address am I supposed to pass to resolve_dynamic_type?
The simple answer would be "the address of the array", but then,
we get back to the question I have been trying to ask: ARR may
not be an lval_memory, in which case "the address of the array"
is meaningless. And reducing a struct value back to an address
feels like information degradation. To give even more context,
I know there are bugs in GDB I can't fix until I convert it from
contents-and-address to values, except the conversion appears
hard to do on its own. So, I think it's worth pausing on this
a little, and try to think things through before we decide that,
indeed, an address is sufficient for our expected needs.

Re: [PATCH 00/23] Fortran dynamic array support

[Jan Kratochvil]

[-- Attachment #1: Type: text/plain, Size: 2236 bytes --]

Hi,

sorry if it was discussed before but I have tried to rebase testcases from my
former/broken VLA implementation archer/jankratochvil/vla to this patchset of
yours and I have found some regressions.

I have updated the testcases which just now expect slightly different
equivalent output.

For some testcases which behaved IMO better with archer/jankratochvil/vla
but which work well enough with this patchset I have made there KFAILs (38).
	(gdb) p varx(1,5,17)
	Value out of range.
	But it would be more correct to say:
	$1 = <not allocated>

gdb.fortran/subrange.exp has been KFAILed as this patchset does not support
the user input syntax like: print alloc (2, 2:3)

Then remain some IMO real regressions:

FAIL: gdb.fortran/dynamic.exp: p varw filled
FAIL: gdb.arch/x86_64-vla-typedef.exp: p array[1]
FAIL: gdb.arch/x86_64-vla-typedef.exp: p array[2]
FAIL: gdb.arch/x86_64-vla-typedef.exp: p array[3]
FAIL: gdb.arch/x86_64-vla-typedef.exp: p array[4]
FAIL: gdb.fortran/string.exp: ptype f
FAIL: gdb.fortran/string.exp: ptype *f
FAIL: gdb.fortran/string.exp: p f
FAIL: gdb.fortran/string.exp: p *f re-set
FAIL: gdb.pascal/arrays.exp: Print dynamic array of string (GDB internal error)
FAIL: gdb.pascal/arrays.exp: Print static array of string (GDB internal error)

I guess you ignored Pascal so that is OK.

For the remaining FAIL cases maybe the DWARF or inferior data are wrong but
I cannot say so myself, have you investigated those?

For example the first one:
	p varw
	$23 = (( ( 6, 5, 1, 5, 5) ( 3, 3, 3, 5, 5) ( 5, 5, 5, 3, 3) ( 3, 5, 5, 5, 5) ) ( ( 3, 3, 3, 3, 3) ( 3, 3, 3, 3, 3) ( 3, 3, 3, 3, 3) ( 3, 3, 3, 3, 3) ) ( ( 5, 5, 5, 5, 5) ( 3, 3, 3, 5, 5) ( 5, 5, 5, 3, 3) ( 3, 5, 5, 5, 5) ) )
	(gdb) FAIL: gdb.fortran/dynamic.exp: p varw filled

seems to me obviously as a bug in GDB as the inferior does there
  varw(:, :, :) = 5                             ! vary-filled
  varw(1, 1, 1) = 6
plus GDB sets that '1' there but all the values '3' come from some
incompatible address calculation between GDB and gfortran-built inferior.

All has been tested on Fedora 20 x86_64 (gcc-4.8.2-7.fc20.x86_64).
Patchset has been applied to: gdb-7.7.90.20140613.tar.bz2
Maybe you have tested it with icc/ifort instead?


Thanks,
Jan

just a little update, I omitted some of the testcases.

Remain some IMO real regressions:

I find here the patch is incomplete.  Earlier this function has:
  unsigned int elt_offs = elt_size * longest_to_int (index - lowerbound);

and in some cases - specifically with the 64-bit inferior objects patch, the
*bitpos* patches from:
	http://pkgs.fedoraproject.org/cgit/gdb.git/tree/
one occasionally gets for TYPE_NOT_ALLOCATED inferior variables:
	Value out of range.
instead of the more correct:
	no such vector element because not allocated

Because for TYPE_NOT_ALLOCATED inferior variable the LOWERBOUND value read
from the inferior is bogus and 'index - lowerbound' will not fit in 'int'.

Thanks for trying out the tests on your system. The test source was
incorrect. I tried to allocate a string, which wasn't deallocated before.
GFORTRAN 4.8.2, which I have on my system, doesn't complain about this mistake,
whereas GFORTRAN 4.9.0 does.
I fixed it and it resolves all of the FAIL's reported above.

We tried to follow the DWARF standard to get this implemented. The DWARF
standard says that this scenario cannot happen in combination with the
DW_OP_push_object_address operation:

"The DW_OP_push_object_address operation pushes the _address_ of the 
object currently being evaluated as part of evaluation of a user presented
expression [...] This operator provides explicit functionality (especially 
for arrays involving descriptors) that is analogous to the implicit push 
of the base address of a structure prior to evaluation of a 
DW_AT_data_member_location to access a data member of a structure."
DWARF Debugging Information Format, Version 4.

So I think having only the address here seems to be ok.

I agree with you that having a struct value instead of an address gives 
more flexibility, but for now I think this is not required according to 
the DWARF standard. If there is a real-world use-case where a full struct 
value object is required instead of having only the address, then this
functionality can be added after this patch series.

The patch series has been outdated, due to the introduction of two 
new functions by Tom (resolve_dynamic_struct and resolve_dynamic_union). 
Shall I therefore submit version 2?

This change just adds some more information for the already existing
"no such vector element" message. To me the change you are describing
sounds more like a generic fix for this function or am I wrong?

Thanks for doing this. I'll try to reproduce these issues on
my system and investigate.
However, the V1 patch series has been outdated as some of the functionality
Tom introduced (resolve_dynamic_struct and resolve_dynamic_union)
replaces some of my functionality for resolving types.

Please provide also some public GIT repository with the patchset or at least
FSF GDB GIT commit this mail patchset is against.  It is otherwise difficult
to guess which GDB to apply it to and I could also mistake some of minor
porting I had to do.

I am not sure if the fix I suggest belongs to this patch series part but it
definitely belongs to this patch series.  Beforehand if this function
value_subscripted_rvalue was called the parameter 'lowerbound' had to be
always valid.  But by introducting the TYPE_NOT_ALLOCATED functionality
'lowerbound' can be passed invalid and so GDB should not touch it if the
array/type is TYPE_NOT_ALLOCATED.

Otherwise this patchset has a regression against my former VLA patchset on
unallocated Fortran arrays where instead of expected
	no such vector element because not allocated
it sometimes - depending on what is read from uninitialized inferior memory,
therefore not always - prints instead:
	Value out of range.

I had to apply the attached fix.

I am not completely sure this is the right fix - IMO when the array is not
allocated GDB should not try to read the array bound(s) from inferior memory
as there is an undefined value that time.

Thanks for taking the time to try to answer my questions. It all
seems reasonable to you, so I agree with your suggestion. I'd like
to add a function that resolves a value - that way, the work is
going to be centralized at one place. But I would think that
I can take care of this independently of your patch series, so
you do not need to worry about that for this series.

FTR, I gave it a try a few weeks ago being going away for a while,
and found that it was probably not as straightforward as one thought.
Extracting the original value's type and address to create resolved
type is pretty straightforward if you assume that the value address
is always going to be valid if the type uses dynamic properties. But
reconstructing a value from that original value and the new type
seems a lot trickier. If the value has a location, is the location
to be preserved, for instance? I don't want to create a non-lval
value if the original value was an lval.  That way, expressions
involving operators such as the address operator  still work.

Thoughts?
