91e159e93b gdb: add pyproject.toml
When running black to format Python files, files with extension .py.in
are ignored, because they don't end in .py.  Add a pyproject.toml file
to instruct black to pick up these files too.

gdb/ChangeLog:

	* py-project.toml: New.
	* gdb-gdb.py.in: Re-format.

gdb/testsuite/ChangeLog:

	* gdb.python/py-framefilter-gdb.py.in: Re-format.
	* gdb.python/py-framefilter-invalidarg-gdb.py.in: Re-format.

fbb1aaceba gdb: fix field names of GDB's type main_type structure
In commit:

  commit 5b7d941b90
  Date:   Fri Jan 22 12:21:09 2021 -0500

      gdb: add owner-related methods to struct type

two fields of struct maint_type were renamed.  'flag_objfile_owned'
became 'm_flag_objfile_owned' and 'owner' became 'm_owner'.  Update
our python helper script to take this into account.

I've added a basic test that uses the self-test framework to load the
pretty printers, and print a type.

The test relies on stopping in GDB's `value_print` function.

gdb/ChangeLog:

	* gdb-gdb.py.in (StructMainTypePrettyPrinter) <owner_to_string>:
	Updated fields names flag_objfile_owned to m_flag_objfile_owned,
	and owner to m_owner.

gdb/testsuite/ChangeLog:

	* gdb.gdb/python-helper.exp: New file.

b66b4e658f Fix pretty printer of main_type.flds_bnds.bounds
In struct dynamic_prop the members kind and data were renamed to m_kind and
m_data.

And flag_upper_bound_is_count is actually in bounds directly, not in its
high member.

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.

4d0bcfcf62 gdb: update instance_flags field name in gdb-gdb.py.in
Commit 314ad88df6 ("Use type_instance_flags more throughout") changed
the name of field type::instance_flags to type::m_instance_flags.  It
however missed changing it in the gdb-gdb.py.in file, which results in
this when trying to use the pretty-printer:

    (top-gdb) p *val.type
    Traceback (most recent call last):
      File "/home/smarchi/build/binutils-gdb/gdb/gdb-gdb.py", line 116, in to_string
        % TypeFlagsPrinter(self.val['instance_flags']))
      File "/home/smarchi/build/binutils-gdb/gdb/gdb-gdb.py", line 76, in __str__
        flag_list = [flag.short_name for flag in TYPE_FLAGS
      File "/home/smarchi/build/binutils-gdb/gdb/gdb-gdb.py", line 77, in <listcomp>
        if self.val & flag.value]
    gdb.error: Argument to arithmetic operation not a number or boolean.
    $7 =

This patch fixes it.

gdb/ChangeLog:

	* gdb-gdb.py.in (class StructTypePrettyPrinter) <to_string>:
	Change instance_flags to m_instance_flags.

7f5331a885 gdb-gdb.py.in: Fix error when printing range type
I noticed that trying to print the contents of a struct main_type
would fail when the type was a TYPE_CODE_RANGE:

    (gdb) p *type.main_type
    $1 = Python Exception <class 'gdb.error'> There is no member named low_undefined.:

And indeed, Python is right, fields "low_undefined" has been removed
from struct range_bounds back in ... 2014! It was done when we introduced
dynamic bounds handling. This patch fixes gdb-gdb.py.in according to
the new structure.

gdb/ChangeLog:

	* gdb-gdb.py.in (StructMainTypePrettyPrinter.bound_img): New method.
	(StructMainTypePrettyPrinter.bounds_img): Use new "bound_img"
	method to compute the bounds of range types. Also print "[evaluated]"
	if the bounds' values come from a dynamic evaluation.

42a4f53d2b Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

gdb/ChangeLog:

	Update copyright year range in all GDB files.

68ad5fb9aa gdb-gdb.py.in: Fix ordering of TypeFlags objects with Python 3
Python 3 doesn't use __cmp__ to order objects, it uses __lt__.  Because
of this, we get this exception when trying to pretty-print "type"
objects:

I tested it with Python 2.7 as well.

gdb/ChangeLog:

	* gdb-gdb.py.in (TypeFlag) <__cmp__>: Remove.
	<__lt__>: Add.

141ec9f67f Copy gdb-gdb.py to build dir
I have thought for a long time how nice it would be to have cool pretty
printers for GDB's internal types.  Well, turns out there are few
already in gdb-gdb.py!  Unfortunately, if you build GDB outside of the
source directory, that file never gets loaded.  top-gdb will look for a
file called

  ../path/to/build/gdb/gdb-gdb.py

but that file is in the source directory at

  ../path/to/src/gdb/gdb-gdb.py

This patch makes it so we copy it to the build directory, just like we
do for gdb-gdb.gdb.  With this, I can at least see the file getting
automatically loaded:

(top-gdb) info pretty-printer
global pretty-printers:
  builtin
    mpx_bound128
  objfile /home/emaisin/build/binutils-gdb/gdb/gdb pretty-printers:
  type_lookup_function

I noticed that running "make" didn't re-generate gdb-gdb.py from
gdb-gdb.py.in.  That's because it's copied when running the configure
script and that's it.  I added a rule in the Makefile for that (and for
gdb-gdb.gdb too) and added them as a dependency to the "all" target.

gdb/ChangeLog:

	* gdb-gdb.py: Move to...
	* gdb-gdb.py.in: ... here.
	* configure.ac (AC_CONFIG_FILES): Add gdb-gdb.py.
	* Makefile.in (all): Add gdb-gdb.gdb and gdb-gdb.py as
	dependencies.
	(distclean): Remove gdb-gdb.py when cleaning.
	(gdb-gdb.py, gdb-gdb.gdb): New rules.
	* configure: Re-generate.
