gdbserver/gdbsupport: Add .dir-locals.el file 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: https://sourceware.org/gdb/wiki/ContributionChecklist#Copyright_Header 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.

Set emacs default mode for the GDB directory to C++ 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.

Setup .dir-locals.el to use C-style comments by default 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.

gdb/emacs/dir-locals: Update settings for c++-mode 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.
