Since modinfo support was added, Meson fixed several issues with extract_objects and compile_commands.json lookups can be simplified. If the lookup uses the object file as key, there is no need to use the command line to distinguish among all entries for a given source. Ninja 1.9 is required in order to produce the 'output' key in compile_commands.json; it is available in CentOS Stream 9, Debian 11, SLES 15.2, Ubuntu 20.04 and in all recent BSD distros. Samurai also has it. Cc: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
