c8f02daac9 Simplify MULTI_SUBSCRIPT implementation
The MULTI_SUBSCRIPT code in evaluate_subexp_standard has a comment
saying that perhaps the EVAL_SKIP handling is incorrect.  This patch
simplifies this code.  In particular, it precomputes all the indices
in a separate loop and removes some complicated flow-control.

Tested using the gdb.modula2 and gdb.dlang test suites, as these are
the only parsers that emit MULTI_SUBSCRIPT.

b7874836c3 gdb: avoid resolving dynamic properties for non-allocated arrays
In PR gdb/27059 an issue was discovered where GDB would sometimes
trigger undefined behaviour in the form of signed integer overflow.
The problem here is that GDB was reading random garbage from the
inferior memory space, assuming this data was valid, and performing
arithmetic on it.

This bug raises an interesting general problem with GDB's DWARF
expression evaluator, which is this:

We currently assume that the DWARF expressions being evaluated are
well formed, and well behaving.  As an example, this is the expression
that the bug was running into problems on, this was used as the
expression for a DW_AT_byte_stride of a DW_TAG_subrange_type:

	DW_OP_push_object_address;
	DW_OP_plus_uconst: 88;
	DW_OP_deref;
	DW_OP_push_object_address;
	DW_OP_plus_uconst: 32;
	DW_OP_deref;
	DW_OP_mul

Two values are read from the inferior and multiplied together.  GDB
should not assume that any value read from the inferior is in any way
sane, as such the implementation of DW_OP_mul should be guarding
against overflow and doing something semi-sane here.

However, it turns out that the original bug PR gdb/27059, is hitting a
more specific case, which doesn't require changes to the DWARF
expression evaluator, so I'm going to leave the above issue for
another day.

In the test mentioned in the bug GDB is actually trying to resolve the
dynamic type of a Fortran array that is NOT allocated.  A
non-allocated Fortran array is one that does not have any data
allocated for it yet, and even the upper and lower bounds of the array
are not yet known.

It turns out that, at least for gfortran compiled code, the data
fields that describe the byte-stride are not initialised until the
array is allocated.

This leads me to the following conclusion: GDB should not try to
resolve the bounds, or stride information for an array that is not
allocated (or not associated, a similar, but slightly different
Fortran feature).  Instead, each of these properties should be set to
undefined if the array is not allocated (or associated).

That is what this commit does.  There's a new flag that is passed
around during the dynamic array resolution.  When this flag is true
the dynamic properties are resolved using the DWARF expressions as
they currently are, but when this flag is false the expressions are
not evaluated, and instead the properties are set to undefined.

efd7ff149a Add expected type parameter to evaluate_expression
While working on the expression rewrite, I found a few spots that
called the internal functions of the expression evaluator, just to
pass in an expected type.  This patch adds a parameter to
evaluate_expression so that these functions can avoid this dependency.

Regression tested on x86-64 Fedora 28.

1ab8280d7d Clean up arguments to evaluate_subexp_do_call
I noticed hat evaluate_subexp_do_call takes an array of arguments and
a count -- but, unlike the usual convention, the count does not
include the first element.

This patch changes this function to match call_function_by_hand --
passing the callee separately, and using an array_view for the
arguments.  This makes it simpler to understand.

Regression tested on x86-64 Fedora 28.

f5756acc15 Constify parse_and_eval_type
I noticed that the argumen to parse_and_eval_type could be "const".
This patch implements this change.

I wonder if this could be removed.  It's only called via
check_stub_method_group, which seems questionable to me.  However, I
didn't look into doing this.

1f8d288117 gdb: make get_discrete_bounds return bool
get_discrete_bounds currently has three possible return values (see its
current doc for details).  It appears that for all callers, it would be
sufficient to have a boolean "worked" / "didn't work" return value.

Change the return type of get_discrete_bounds to bool and adjust all
callers.  Doing so simplifies the following patch.

gdb/ChangeLog:

	* gdbtypes.h (get_discrete_bounds): Return bool, adjust all
	callers.
	* gdbtypes.c (get_discrete_bounds): Return bool.

dda83cd783 gdb, gdbserver, gdbsupport: fix leading space vs tabs issues
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).

8c37706a51 gdb/fortran: Clean up array/string expression evaluation
This commit is a refactor of part of the Fortran array and string
handling code.

The current code is split into two blocks, linked, weirdly, with a
goto.  After this commit all the code is moved to its own function,
and arrays and strings are now handled using the same code; this will
be useful later when I want to add array stride support where strings
will want to be treated just like arrays, but is a good clean up even
without the array stride work, which is why I'm merging it now.

For now the new function is added as a static within eval.c, even
though the function is Fortran only.  A following commit will remove
some of the Fortran specific code from eval.c into one of the Fortran
specific files, including this new function.

There should be no user visible changes after this commit.

gdb/ChangeLog:

	* eval.c (fortran_value_subarray): New function, content is taken
	from...
	(evaluate_subexp_standard): ...here, in two places.  Now arrays
	and strings both call the new function.
	(calc_f77_array_dims): Add header comment, handle strings.

314ad88df6 Use type_instance_flags more throughout
A later patch in this series will rewrite enum_flags fixing some API
holes.  That would cause build failures around code using
type_instance_flags.  Or rather, that should be using it, but wasn't.

This patch fixes it by using type_instance_flags throughout instead of
plain integers.

Note that we can't make the seemingly obvious change to struct
type::instance_flags:

 -  unsigned instance_flags : 9;
 +  ENUM_BITFIELD (type_instance_flag_value) instance_flags : 9;

Because G++ complains then that 9 bits isn't sufficient for holding
all values of type_instance_flag_value.

So the patch adds an type::instance_flags() method, which takes care
of casting appropriately, and adds a separate type::set_instance_flags
method, following the pattern of the ongoing TYPE_XXX macro
elimination.  This converts uses of TYPE_INSTANCE_FLAGS to
type::instance_flags() in the places where the code was already being
touched, but there are still many references to the
TYPE_INSTANCE_FLAGS macro left behind.  Those could/should be fully
replaced at some point.

	type_instance_flags.

cf88be6855 gdb: make type::bounds work for array and string types
Getting the bounds of an array (or string) type is a common operation,
and is currently done through its index type:

    my_array_type->index_type ()->bounds ()

I think it would make sense to let the `type::bounds` methods work for
arrays and strings, as a shorthand for this.  It's natural that when
asking for the bounds of an array, we get the bounds of the range type
used as its index type.  In a way, it's equivalent as the now-removed
TYPE_ARRAY_{LOWER,UPPER}_BOUND_IS_UNDEFINED and
TYPE_ARRAY_{LOWER,UPPER}_BOUND_VALUE, except it returns the
`range_bounds` object.  The caller is then responsible for getting the
property it needs in it.

I updated all the spots I could find that could take advantage of this.

Note that this also makes `type::bit_stride` work on array types, since
`type::bit_stride` uses `type::bounds`.  `my_array_type->bit_stride ()`
now returns the bit stride of the array's index type.  So some spots
are also changed to take advantage of this.

	types.

5d14b6e5d6 gdb: add field::type / field::set_type
Add the `type` and `set_type` methods on `struct field`, in order to
remoremove the `FIELD_TYPE` macro.  In this patch, the `FIELD_TYPE`
macro is changed to use `field::type`, so all the call sites that are
useused to set the field's type are changed to use `field::set_type`.
The next patch will remove `FIELD_TYPE` completely.

Note that because of the name clash between the existing field named
`type` and the new method, I renamed the field `m_type`.  It is not
private per-se, because we can't make `struct field` a non-POD yet, but
it should be considered private anyway (not accessed outside `struct
field`).

gdb/ChangeLog:

	* gdbtypes.h (struct field) <type, set_type>: New methods.
	Rename `type` field to...
	<m_type>: ... this.  Change references throughout to use type or
	set_type methods.

ceacbf6edf gdb: remove TYPE_FIELD macro
Replace all uses of it by type::field.

Note that since type::field returns a reference to the field, some spots
are used to assign the whole field structure.  See ctfread.c, function
attach_fields_to_type, for example.  This is the same as was happening
with the macro, so I don't think it's a problem, but if anybody sees a
really nicer way to do this, now could be a good time to implement it.

d5a22e77b5 Remove gdbarch_bits_big_endian
From what I can tell, set_gdbarch_bits_big_endian has never been used.
That is, all architectures since its introduction have simply used the
default, which is simply check the architecture's byte-endianness.

Because this interferes with the scalar_storage_order code, this patch
removes this gdbarch setting entirely.  In some places,
type_byte_order is used rather than the plain gdbarch.

55708e99ac Allow re-assigning to convenience variables
A customer reported somewhat odd gdb behavior, where re-assigning an
array or string to a convenience variable would yield "Too many array
elements".  A test case is:

    (gdb) p $x = "x"
    (gdb) p $x = "xyz"

This patch fixes the problem by making a special case in the evaluator
for assignment to convenience variables, which seems like the correct
behavior.

Note that a previous patch implemented this for Ada, see commit
f411722cb ("Allow re-assigning to convenience variables").
