0958441403 Add support for printing value of DWARF-based fixed-point type objects 
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.

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).

00c696a6e2 gdb: remove LA_VALUE_PRINT macro 
Remove the LA_VALUE_PRINT macro, and replace its uses with direct
calls to the value_print member function on an appropriate language.

In the global 'value_print' function, we call the value_print method
on the current_language, this is a direct inline replacement of the
old LA_VALUE_PRINT macro.

However, in ada-lang.c, and language.c the macro was being used
within the print_array_index member function of a language class.  In
these cases we now call the value_print member function of the current
language class.

In theory, when we are inside (for example) the
ada_language::print_array_index function the current_language should
always be set to Ada, so this change should have no effect.  However,
if we ever could get into ada_language::print_array_index with the
current language set to something else (which I think would have been
a bug) then we would now see a change in behaviour.  I couldn't find
any cases where this happened though.

There should be no user visible changes after this commit, but it is
not impossible in some edge cases.

	* ada-lang.c (ada_language::print_array_index): Call value_print
	directly.
	* language.c (language_defn::print_array_index): Likewise.
	* language.h (LA_VALUE_PRINT): Delete.
	* valprint.c (value_print): Call value_print on the
	current_language directly.

cfabbd351a Make range types inherit signed-ness from base type 
I ran across this comment in valprint.c:

      /* FIXME: create_static_range_type does not set the unsigned bit in a
         range type (I think it probably should copy it from the target
         type), so we won't print values which are too large to
         fit in a signed integer correctly.  */

It seems to me that a range type ought to inherit its signed-ness from
the underlying type, so this patch implements this change, and removes
the comment.  (It was also copied into m2-valprint.c.)

I also remove the comment about handling ranges of enums, because I
think that comment is incorrect.

53a47a3e49 Handle indexing Ada arrays with enum indices 
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.

d642b6920b Fix array pretty formatter 
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

0743fc83c0 Replace most calls to help_list and cmd_show_list 
Currently there are many prefix commands that do nothing but call
either help_list or cmd_show_list.  I happened to notice that one such
call, for "set print type", used the wrong command list parameter,
causing incorrect output.

Rather than fix this bug in isolation, I decided to eliminate this
possibility by adding two new ways to add prefix commands, which
simply route the call to help_list or cmd_show_list, as appropriate.
This makes it impossible for a mismatch to occur.

In some cases, a bit of output was removed; however, I don't think
this output in general was very useful.  It seemed redundant with
what's already printed by help_list.  A representative example is this
hunk, removed from ada-lang.c:

-  printf_unfiltered (_(\
-"\"set ada\" must be followed by the name of a setting.\n"));

This simplified the CLI style set/show commands quite a bit, and
allowed the deletion of a macro.

This also cleans up some unusual code in windows-tdep.c.

Tested on x86-64 Fedora 30.  Note that I have no way to build the
go32-nat.c change.

42331a1ea2 Change extension language pretty-printers to use value API 
This changes the extension language pretty-printers to use the value
API.

Note that new functions were needed, for both Guile and Python.
Currently both languages always wrap values by removing the values
from the value chain.  This makes sense to avoid strange behavior with
watchpoints, and to avoid excessive memory use.  However, when
printing, it's important to leave the passed-in value untouched, in
case pretty-printing does nothing -- that way the caller can still
access it.

The plan for removing val_print is, essentially, to first duplicate

incrementally while keeping everything working.

This adds a new la_value_print_inner function pointer to struct
language_defn.  Eventually this will replace la_val_print.  This patch
also changes printing to prefer this API, when available -- but no
language defines it yet.

c2a44efee1 Introduce common_val_print_checked 
A (much) later patch will remove the call to value_check_printable
from common_val_print.  This will needed to preserve some details of
how optimized-out structures are printed.

However, doing this will also break dw2-op-out-param.exp.  Making the
change causes "bt" to print:

However, the test wants to see:

... operand2=<optimized out>

That is, a wholly-optimized out structure should not print its fields.

So, this patch introduces a new common_val_print_checked, which calls
value_check_printable first, and then arranges to use it in the one
spot that affects the test suite.

I was not completely sure if it would be preferable to change the
test.  However, I reasoned that, assuming this output was intentional
in the first place, in a backtrace space is at a premium and so this
is a reasonable approach.  In other spots calling common_val_print,
this behavior is probably unintended, or at least a "don't care".

Switching the low-level printing to use the value API means we will be
using more temporary values.  This adds a scoped_value_mark to
value_print, so that these intermediates are destroyed in a timely
way.

3f0cbb04d0 Style field names in "print" 
This changes gdb to use the "variable" style when printing field
names.  I've added new tests for C and Rust, but not other languages.

I chose "variable" because that seemed most straightforward.  However,
another option would be to introduce a new "field" style.  Similarly,
this patch uses the variable style for enumerator constants -- but
again, a new style could be used if that's preferred.

373d7ac0f1 gdb: change print format of flag enums with value 0 
If a flag enum has value 0 and the enumeration type does not have an
enumerator with value 0, we currently print:

  $1 = (unknown: 0x0)

I don't like the display of "unknown" here, since for flags, 0 is a
an expected value.  It just means that no flags are set.  This patch
makes it so that we print it as a simple 0 in this situation:

  $1 = 0

If there is an enumerator with value 0, it is still printed using that
enumerator, for example (from the test):

  $1 = FE_NONE

gdb/ChangeLog:

	* valprint.c (generic_val_print_enum_1): When printing a flag
	enum with value 0 and there is no enumerator with value 0, print
	just "0" instead of "(unknown: 0x0)".

b29a2df000 gdb: print unknown part of flag enum in hex 
When we print the "unknown" part of a flag enum, it is printed in
decimal.  I think it would be more useful if it was printed in hex, as
it helps to determine which bits are set more than a decimal value.

6740f0cc3b gdb: allow duplicate enumerators in flag enums 
I have come across some uses cases where it would be desirable to treat
an enum that has duplicate values as a "flag enum".  For example, this
one here [1]:

    enum membarrier_cmd {
            MEMBARRIER_CMD_QUERY                                = 0,
            MEMBARRIER_CMD_GLOBAL                               = (1 << 0),
            MEMBARRIER_CMD_GLOBAL_EXPEDITED                     = (1 << 1),
            MEMBARRIER_CMD_REGISTER_GLOBAL_EXPEDITED            = (1 << 2),
            MEMBARRIER_CMD_PRIVATE_EXPEDITED                    = (1 << 3),
            MEMBARRIER_CMD_REGISTER_PRIVATE_EXPEDITED           = (1 << 4),
            MEMBARRIER_CMD_PRIVATE_EXPEDITED_SYNC_CORE          = (1 << 5),
            MEMBARRIER_CMD_REGISTER_PRIVATE_EXPEDITED_SYNC_CORE = (1 << 6),

            /* Alias for header backward compatibility. */
            MEMBARRIER_CMD_SHARED = MEMBARRIER_CMD_GLOBAL,
    };

The last enumerator is kept for backwards compatibility.  Without this
patch, this enumeration wouldn't be considered a flag enum, because two
enumerators collide.   With this patch, it would be considered a flag
enum, and the value 3 would be printed as:

  MEMBARRIER_CMD_GLOBAL | MEMBARRIER_CMD_GLOBAL_EXPEDITED

Although if people prefer, we could display both MEMBARRIER_CMD_GLOBAL
and MEMBARRIER_CMD_SHARED in the result.  It wouldn't be wrong, and
could perhaps be useful in case a bit may have multiple meanings
(depending on some other bit value).

edd45eb06b gdb: fix printing of flag enums with multi-bit enumerators 
GDB has this feature where if an enum looks like it is meant to
represent binary flags, it will present the values of that type as a
bitwise OR of the flags that are set in the value.

The original motivation for this patch is to fix this behavior:

  enum hello { AAA = 0x1, BBB = 0xf0 };

  (gdb) p (enum hello) 0x11
  $1 = (AAA | BBB)

This is wrong because the bits set in BBB (0xf0) are not all set in the
value 0x11, but GDB presents it as if they all were.

I think that enumerations with enumerators that have more than one bit
set should simply not qualify as "flag enum", as far as this
heuristic is concerned.  I'm not sure what it means to have flags of
more than one bit.  So this is what this patch implements.

I have added an assert in generic_val_print_enum_1 to make sure the flag
enum types respect that, in case they are used by other debug info
readers, in the future.

I've enhanced the gdb.base/printcmds.exp test to cover this case.  I've
also added tests for printing flag enums with value 0, both when the
enumeration has and doesn't have an enumerator for value 0.

gdb/ChangeLog:

	* dwarf2/read.c: Include "count-one-bits.h".
	(update_enumeration_type_from_children): If an enumerator has
	multiple bits set, don't treat the enumeration as a "flag enum".
	* valprint.c (generic_val_print_enum_1): Assert that enumerators
	of flag enums have 0 or 1 bit set.

gdb/testsuite/ChangeLog:

	* gdb.base/printcmds.c (enum flag_enum): Prefix enumerators with
	FE_, add FE_NONE.
	(three): Update.
	(enum flag_enum_without_zero): New enum.
	(flag_enum_without_zero): New variable.
	(enum not_flag_enum): New enum.
	(three_not_flag): New variable.
	* gdb.base/printcmds.exp (test_artificial_arrays): Update.
	(test_print_enums): Add more tests for printing flag enums.

6c2659886f gdb: add back declarations for _initialize functions 
I'd like to enable the -Wmissing-declarations warning.  However, it
warns for every _initialize function, for example:

      CXX    dcache.o
    /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
    /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
     _initialize_dcache (void)
     ^~~~~~~~~~~~~~~~~~

The only practical way forward I found is to add back the declarations,
which were removed by this commit:

    commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9
    Author: John Baldwin <jhb@FreeBSD.org>
    Date:   Sat Sep 9 11:02:37 2017 -0700

        Remove unnecessary function prototypes.

I don't think it's a big problem to have the declarations for these
functions, but if anybody has a better solution for this, I'll be happy
to use it.

d8edc8b768 Implement 'print -raw-values' and 'set print raw-values on|off' 
The option framework documentation was speaking about a 'print -raw'
option, but this option does not exist.

This patch implements -raw-values option that tells to ignore the
active pretty printers when printing a value.
As we already have -raw-frame-arguments, I thought -raw-values
was more clear, in particular to differentiate
   set print raw-values and set print raw-frame-arguments.

gdb/doc/ChangeLog
2019-12-11  Philippe Waroquiers  <philippe.waroquiers@skynet.be>

	* gdb.texinfo (Command Options): Use -p and -pretty in the example,
	as -r is ambiguous.  Update the print - TAB TAB completion result.
	(Data): Document new option -raw-values.  Use -p and -pretty in the
	 example, as -r is ambiguous.
	(Print Settings): Document set print raw values.
	(Pretty-Printer Commands): Document interaction between enabled
	pretty printers and -raw-values/-raw-frame-arguments.

gdb/ChangeLog
2019-12-11  Philippe Waroquiers  <philippe.waroquiers@skynet.be>

	* NEWS: Document -raw-values option and the related setting commands.
	* printcmd.c (print_command_parse_format): Do not set opts->raw off,
	only set it on when /r is given.
	* valprint.c (value_print_option_defs): New element raw-values.
	* Makefile.in: Add the new file.

gdb/testsuite/ChangeLog
2019-12-11  Philippe Waroquiers  <philippe.waroquiers@skynet.be>

	* gdb.base/options.exp: Add -raw-values in the print completion list.
	* gdb.python/py-prettyprint.exp: Add tests for -raw-values.

2dbc041e4e Use metadata style in a few more places 
I happened to find a few more spots that should use metadata style,
but do not.  I missed these in my earlier search somehow.  This patch
also adds gettext markup in a couple of spots where it was missing.

	* valprint.c (val_print_string): Use metadata_style.

	* p-valprint.c (pascal_object_print_static_field): Use metadata
	style.
	* cp-valprint.c (cp_print_static_field): Use metadata style.
