convert to_supports_btrace
This adds a "self" argument to to_supports_btrace. Due to how one implementation of this method is shared with gdbserver this required a small change to gdbserver as well. 2014-02-19 Tom Tromey <tromey@redhat.com> * common/linux-btrace.c (linux_supports_btrace): Add "ops" argument. * common/linux-btrace.h (linux_supports_btrace): Update. * remote.c (remote_supports_btrace): Add "self" argument. * target-delegates.c: Rebuild. * target.c (target_supports_btrace): Remove. * target.h (struct target_ops) <to_supports_btrace>: Add target_ops argument. (target_supports_btrace): New define. 2014-02-19 Tom Tromey <tromey@redhat.com> * target.h (struct target_ops) <supports_btrace>: Add target_ops argument. (target_supports_btrace): Update.
