I looked at all the spots using value_mark, and converted all the
straightforward ones to use scoped_value_mark instead.

print_spaces_filtered is now misnamed, because whether filtering
happens is up to the stream. So, rename it.
|
|
Now that filtered and unfiltered output can be treated identically, we
can unify the printf family of functions. This is done under the name
"gdb_printf". Most of this patch was written by script.

ada_print_floating rewrites a floating-point string representation to
conform to Ada syntax. However, if you managed to get a floating
point error, you might see:
(gdb) print whatever
$2 = <invalid float valu.0e>
What's happening here is that ada_print_floating doesn't recognize
this error case, and proceeds to modify the error text.
This patch fixes this problem.
|
|
As noted in an earlier patch, the Ada lexer does not handle multi-byte
bracket sequences. This patch adds support for these for character
literals. gdb does not generally seem to handle the Ada wide string
types, so for the time being these continue to be excluded -- but an
explicit error is added to make this more clear.

|
This removes the LA_PRINT_CHAR macro, in favor of using ordinary
method calls.
|
|
This changes all existing calls to wrap_here to call the method on the
appropriate ui_file instead. The choice of ui_file is determined by
context.
|
|
I think it only really makes sense to call wrap_here with an argument
consisting solely of spaces. Given this, it seemed better to me that
the argument be an int, rather than a string. This patch is the
result. Much of it was written by a script.
|
|
A common pattern for string_file is to want to move out the internal
string buffer, because it is the result of the computation that we want
to return. It is the reason why string_file::string returns a non-const
reference, as explained in the comment. I think it would make sense to
have a dedicated method for that instead and make string_file::string
return a const reference.
This allows removing the explicit std::move in the typical case. Note
that compile_program::compute was missing a move, meaning that the
resulting string was copied. With the new version, it's not possible to
forget to move.

I noticed that the only caller of ada_value_print_inner is
valprint.c:do_val_print (via ada_language::value_print_inner), meaning
that the try/catch logic in this function is redundant. This patch
removes the wrapper function.
Regression tested on x86-64 Fedora 34.

The bug fixed by this [1] patch was caused by an out-of-bounds access to
a value's content. The code gets the value's content (just a pointer)
and then indexes it with a non-sensical index.
This made me think of changing functions that return value contents to
return array_views instead of a plain pointer. This has the advantage
that when GDB is built with _GLIBCXX_DEBUG, accesses to the array_view
are checked, making bugs more apparent / easier to find.
This patch changes the return types of these functions, and updates
callers to call .data() on the result, meaning it's not changing
anything in practice. Additional work will be needed (which can be done
little by little) to make callers propagate the use of array_view and
reap the benefits.

This makes the Ada-specific "varsize-limit" a synonym for
"max-value-size", and removes the Ada-specific checks of the limit.
I am not certain of the history here, but it seems to me that this
code is fully obsolete now. And, removing this makes it possible to
index large Ada arrays without triggering an error. A new test case
is included to demonstrate this.

Remove the `TYPE_FIELD_NAME` and `FIELD_NAME` macros, changing all the
call sites to use field::name directly.

Currently, the Ada expression parser treats 'null' as an integer 0.
However, this causes overloading to fail in certain cases.
This patch changes the Ada expression parser to use a special type for
'null'. I chose pointer-to-int0, because I think that's not likely to
be needed for any other Ada expression. Note this works because a
"mod 1" type has an underlying non-zero byte size; the test includes a
check for this.
The output is changed so that "print null", by default, shows "null".
And, ada_type_match is changed both to recognize the special null type
and to remove a bit of weird code related to how pointers are treated
for overload type matching.
Tested on x86-64 Fedora 32. Because this only touches Ada, and Joel
already approved it internally at AdaCore, I am checking it in.

The Ada value-printing code could crash when printing an array which
had been optimized out.
The crash is difficult to reproduce, but I did manage to write a test
that at least shows that the previous behavior was incorrect -- before
the patch, the array is printed as if it is valid and every value is 0.

gdb currently supports two different styles of fixed-point. The
original style, where fixed point types are "GNAT encoded", is handled
primarily in the Ada code. The newer style, encoded using DWARF, is
handled by the core of gdb.
This patch changes gdb to read the GNAT encodings in the DWARF reader
as well. This removes some code and unifies the two paths. As a
result, GNAT-encoded fixed-point now works a bit better.
One possible drawback of this change is that, if someone uses stabs,
then fixed-point might now stop working. I consider stabs to be fully
obsolete, though, so I don't intend to address this.

get_discrete_bounds currently has three possible return values (see its

callers. Doing so simplifies the following patch.

As suggested by Simon, to logically connect this function to
the object it inspects.
Note that, logically, this method should be "const". Unfortunately,
the implementation iterates on struct type objects starting with "this",
and thus trying to declare the method "const" triggers a compilation
error.

* gdbtypes.h (struct type) <fixed_point_type_base_type> New method,
replacing the fixed_point_type_base_type function. All callers
updated throughout this project.

This commit introduces a new kind of type, meant to describe
fixed-point types, using a new code added specifically for
this purpose (TYPE_CODE_FIXED_POINT).
It then adds handling of fixed-point base types in the DWARF reader.
And finally, as a first step, this commit adds support for printing
the value of fixed-point type objects.
Note that this commit has a known issue: Trying to print the value
of a fixed-point object with a format letter (e.g. "print /x NAME")
causes the wrong value to be printed because the scaling factor
is not applied. Since the fix for this issue is isolated, and
this is not a regression, the fix will be made in a pach of its own.
This is meant to simplify review and archeology.
Also, other functionalities related to fixed-point type handling
(ptype, arithmetics, etc), will be added piecemeal as well, for
the same reasons (faciliate reviews and archeology). Related to this,
the testcase gdb.ada/fixed_cmp.exp is adjusted to compile the test
program with -fgnat-encodings=all, so as to force the use of GNAT
encodings, rather than rely on the compiler's default to use them.
The intent is to enhance this testcase to also test the pure DWARF
approach using -fgnat-encodings=minimal as soon as the corresponding
suport gets added in. Thus, the modification to the testcase is made
in a way that it prepares this testcase to be tested in both modes.

When -fgnat-encodings=minimal, the compiler will avoid the special
GNAT-specific "encodings" format, and instead emit ordinary DWARF as
much as possible.
When emitting DWARF for thick pointers to arrays, the compiler emits
something like:
<1><11db>: Abbrev Number: 7 (DW_TAG_array_type)
<11dc> DW_AT_name : (indirect string, offset: 0x1bb8): string
<11e0> DW_AT_data_location: 2 byte block: 97 6
(DW_OP_push_object_address; DW_OP_deref)
<11e3> DW_AT_type : <0x1173>
<11e7> DW_AT_sibling : <0x1201>
<2><11eb>: Abbrev Number: 8 (DW_TAG_subrange_type)
<11ec> DW_AT_type : <0x1206>
<11f0> DW_AT_lower_bound : 6 byte block: 97 23 8 6 94 4
(DW_OP_push_object_address; DW_OP_plus_uconst: 8; DW_OP_deref;
DW_OP_deref_size: 4)
<11f7> DW_AT_upper_bound : 8 byte block: 97 23 8 6 23 4 94 4
(DW_OP_push_object_address; DW_OP_plus_uconst: 8; DW_OP_deref;
DW_OP_plus_uconst: 4; DW_OP_deref_size: 4)
If you read between the lines, the "array" is actually a structure
with two elements. One element is a pointer to the array data, and
the other structure describes the bounds of the array. However, the
compiler doesn't emit this explicitly, but instead hides it behind
these location expressions.
gdb can print such objects, but currently there is no way to construct
one. So, this patch adds some code to the DWARF reader to recognize
this construct, and then synthesize an array descriptor. This
descriptor is then handled by the existing Ada code.
Internally, we've modified GCC to emit the structure type explicitly
(we will of course be sending this upstream). In this case, the array
still has the DW_AT_data_location, though. This patch also modifies
gdb to ignore the data location in this case -- this is preferred
because the location only serves to confuse the Ada code that already
knows where to find the data. In the future I hope to move some of
this handling to the gdb core, so that Ada-specific hacks are not
needed; however I have not yet done this.
Because parallel types are not emitted with -fgnat-encodings=minimal,
some changes to the Ada code were also required.
The change ina ada-valprint.c was needed to avoid infinite recursion
when trying to print a constrained packed array. And, there didn't
seem to be any need for a recursive call here -- the value could
simply be returned instead.
Finally, gdb.ada/frame_arg_lang.exp no longer works in C mode, because
we drop back to the structure approach now. As mentioned earlier,
future work should probably fix this again; meanwhile, this doesn't
seem to be a big problem, because it is what is currently done (users
as a rule don't use -fgnat-encodings=minimal -- which is what I am
ultimately trying to fix).
Note that a couple of tests have an added KFAIL. Some
-fgnat-encodings=minimal changes have landed in GNAT, and you need
something very recent to pass all the tests. I'm using git gcc to
accomplish this.

Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c). I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it? What if the lines around it are also
wrong, do I fix them too? I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.
So I propose to fix as much as possible once and for all (hopefully).
One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines. My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for. So you
already need a somewhat efficient way to do this.
Using some interactive tool, rather than plain git-blame, makes this
trivial. For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too. My point is that it won't
really make archeology more difficult.
The other typical counter argument is that it will cause conflicts with
existing patches. That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve. I have also tried "git
rebase --ignore-whitespace", it seems to work well. Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

This patch renames some of the fixed-point-related subprograms in ada-lang.c
so as to make it obvious that those routines only handle the case where
the types are encoded using the GNAT encoding.

for fixed-point types purely based on standard DWARF debug info.

Add the `is_unsigned` and `set_is_unsigned` methods on `struct type`, in
order to remove the `TYPE_UNSIGNED` macro. In this patch, the
`TYPE_UNSIGNED` macro is changed to use `type::is_unsigned`, so all the
call sites that are used to set this property on a type are changed to
use the new method. The next patch will remove the macro completely.
gdb/ChangeLog:
* gdbtypes.h (struct type) <is_unsigned, set_is_unsigned>: New

In Ada, like C, an enum can assign values to the constants. However,
unlike C (or any other language supported by gdb), the enum type can
also be used as the range of an array.
In this case, the user's code references the enum constants, but the
compiler translates these to the position of the constant in the enum.
So for example one might write:
type Enum_With_Gaps is
(
LIT0,
LIT1,
LIT2,
LIT3,
LIT4
);
for Enum_With_Gaps use
(
LIT0 => 3,
LIT1 => 5,
LIT2 => 8,
LIT3 => 13,
LIT4 => 21
);
Then index an array like "array(LIT3)" -- but this will be the 4th
element in an array of 5 elements, not the 13th element in an array of
19 (assuming I did the math right) elements.
gdb supports this to some degree, with the only missing piece being
indexing into such an array. This patch implements this missing
feature, and also fixes an existing bug, which is that in some
situations I believe gdb would mis-compute the resulting array's
length.
The approach taken here is to try to integrate this feature into the
core of gdb. My view is that much of the Ada support should be better
integrated with gdb, rather than being "on the side". This, I think,
would help avoid code duplication at least. So, I try to take steps
toward this goal when possible.
Because other languages generally don't allow the user to specify the
index type of an array, I simply made the core of gdb unconditionally
apply discrete_position when computing the range of such an array.
This is a no-op for ordinary types, but applies the enum
value-to-position transformation for TYPE_CODE_ENUM.

The purpose of this patch is to prepare for the future where
fixed point types become described using standard DWARF info,
rather than GNAT encodings. For that, we rename a number of
routines manipulating Ada fixed point types to make it explicit
from their new names that they rely on the GNAT encodings to work.
This will allow us, when we introduce support for fixed point types
from standard DWARF to use names that are not ambiguous with
the functions that do similar work, but only for GNAT encodings.

The val_print removal patches introduced an Ada regression on PPC64
(probably any big-endian system).
The issue comes because value_field does not understand that Ada
wrapper fields can be bitfields that wrap a non-scalar type. In this
case the value is already left-justified, so the justification done
there does the wrong thing.
Perhaps it would be good, eventually, to change value_field to
understand this case. In the meantime this implements an Ada-specific
solution.

Currently, printing with array pretty formatting makes the output actually
less readable than without:
(gdb) p -array on -- {{1,2,3},{4,5,6}}
$1 = { {1,
2,
3},
{4,
5,
6}}
(gdb) p -array on -array-indexes on -- {{1,2,3},{4,5,6}}
$2 = {[0] = {[0] = 1,
[1] = 2,
[2] = 3},
[1] = {[0] = 4,
[1] = 5,
[2] = 6}}
These changes now also put the first element and the array end bracket on a new
line, similar to the structure pretty formatter:
(gdb) p -array on -- {{1,2,3},{4,5,6}}
$1 = {
{
1,
2,
3
},
{
4,
5,
6
}
}
(gdb) p -array on -array-indexes on -- {{1,2,3},{4,5,6}}
$2 = {
[0] = {
[0] = 1,
[1] = 2,
[2] = 3
},
[1] = {
[0] = 4,
[1] = 5,
[2] = 6
}

When evaluating a DWARF expression, the dynamic type resolution code
will pass in a buffer of bytes via the property_addr_info. However,
the DWARF expression evaluator will then proceed to read memory from
the inferior, even when the request could be filled from this buffer.
This, in turn, is a problem in some cases; and specifically when
trying to handle the Ada scenario of extracting a variable-length
value from a packed array. Here, the ordinary DWARF expression cannot
be directly evaluated, because the data may appear at some arbitrary
bit offset. So, it is unpacked into a staging area and then the
expression is evaluated -- using an address of 0.
This patch fixes the problem by arranging for the DWARF evaluator, in
this case, to prefer passed-in memory when possible. The type of the
buffer in the property_addr_info is changed to an array_view so that
bounds checking can be done.

When I updated the Ada variant-printing code to be value-based, I
neglected a couple of issues. First, print_variant_part must first
extract the variant field before finding the active component; second,
print_field_values should pass in the field value as the outer value
when recursing.
This patch fixes both of these issues.

While debugging an Ada regression, I noticed that all the callers of
ada_which_variant_applies desconstruct a value, only to have it be
reconstructed by this function.
This patch removes this inefficiency in favor of simply passing in the
value directly.
Tested on x86-64 Fedora 30.

* ada-valprint.c (print_variant_part): Update.
* ada-lang.h (ada_which_variant_applies): Update.
* ada-lang.c (ada_which_variant_applies): Remove outer_type and
outer_valaddr parameters; replace with "outer" value parameter.
(to_fixed_variant_branch_type): Update.

The removal of val_print caused a regression in the Ada code. In one
scenario, a variant type would not be properly printed, because the
address of a component was lost. This patch fixes the bug by changing
this API to be value-based. This is cleaner and fixes the bug as a
side effect.

This converts print_field_values to use the value-based API, by having
it call common_val_print rather than val_print.

This adds ada_value_print_array, a value-based analogue of
ada_val_print_array. It also removes some unused parameters from a
couple of helper functions.
