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.
