Copy the .dir-locls.el file from gdb/ to gdbserver/ and gdbsupport/ so
that we get the GNU/GDB style when editing these files in Emacs.
I initially wanted to remove the (c-mode . ((mode . c++))) that
switches c-mode files into c++-mode as we store C++ code in *.cc files
in the gdbserver/ directory, unlike gdb/ where we use *.c, however, I
was forgetting about the header files - we still use *.h for our C++
header files, so for now I left the settings in place to open all C
files in c++-mode.
We now have three copies of this file, which are all identical. It
would be nice if we could remove this duplication, however, for now we
haven't found a good way to do this.
Some options considered were:
1. Use symlinks to only have one copy of the file. This was
rejected as not all targets support symlinks in the way.
2. Have two of the .dir-locals.el files contain some mechanism by
which the third copy of the file is sourced. Though this would, in
theory, be possible, it would involve some advanced Emacs scripting,
would be fragile, and a maintenance burdon.
3. Move the .dir-locals up into top level src/ directory, then use
Emacs dir-locals directory pattern matching to only apply the rules
for the three directories we care about. The problem is that each
directory has to be listed separately, so we still end up having to
duplicate all the rules.
In the end, it was decided that having three copies of the file,
though not ideal, is probably easiest for now. This was all discussed
in this mailing list thread:
https://sourceware.org/ml/gdb-patches/2020-03/msg00024.html
The copyright date in the new files is left as for gdb/.dir-locals.el,
as the new files are a copy of the old, this is inline with this rule:

gdb/ChangeLog:
* .dir-locals.el: Add a comment referencing the other copies of
this file.
gdbserver/ChangeLog:
* .dir-locals.el: New file.
gdbsupport/ChangeLog:
* .dir-locals.el: New file.
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.
The current .dir-locals file for GDB causes files that would usually
open in c-mode (for example, files ending in .c) to open in c++-mode.
However, all of the other settings applied for c-mode appear to get
reset when the file is switched over to c++-mode.
For example, we currently say:
(c-mode . ((c-file-style . "GNU")
(mode . c++)
(indent-tabs-mode . t)
(tab-width . 8)
(c-basic-offset . 2)
(eval . (c-set-offset 'innamespace 0))
))
(c++-mode . ((eval . (when (fboundp 'c-toggle-comment-style)
(c-toggle-comment-style 1)))))
So, when we enter c++-mode `indent-tabs-mode` is reset to its global
value, as are all of the other settings listed for c-mode.
This commit copies all of the settings (except the `mode` setting)
from the c-mode list to the c++-mode list.
The emacs documentation doesn't mention that `mode` causes this
resetting behaviour, so, in case this is an emacs bug, I'm using emacs
version 26.1. Having the settings duplicated shouldn't cause any
problems except for a slight maintenance overhead.
gdb/ChangeLog:
* .dir-locals.el: Copy most of the settings from c-mode over to
c++-mode.
gdb/ChangeLog:
2017-07-01 Eli Zaretskii <eliz@gnu.org>
* .dir-locals.el: Automatically switch to C-style comments in
versions of Emacs that support the feature.
This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
Since GDB has switched to C++ but the file names are still .c emacs does
not load the proper mode when opening files in the gdb directory.
This patch fixes that by enabling c++ mode.
This patch also fixes indentation tweaks as discussed in this thread:
https://sourceware.org/ml/gdb-patches/2016-12/msg00074.html
Indent with gdb-code-style.el included and the .dir-locals.el is as such:
namespace TestNameSpace {
class test
{
public:
test test() {}
int m_a;
};
struct teststruct
{
int a;
}
}
gdb/ChangeLog:
* .dir-locals.el: Set c++ mode for the directory and set indent
properly.
* gdb-code-style.el: Set c-set-offset 'innamespace as a safe value
to be used in .dir-locals.el.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
