- The interp->data field disappears, since we can put data in the interpreter directly now. The "init" method remains in place, but it now returns void. - A few places check if the interpreter method is NULL before calling it, and also check whether the method returns true/false. For some of those methods, all current implementations always return true. In those cases, this commit makes the C++-fied method return void instead and cleans up the callers. Tested on x86_64 Fedora 23. gdb/ChangeLog: 2017-02-03 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_interp_base::cli_interp_base) (cli_interp_base::~cli_interp_base): New.
