record-btrace: add to_wait and to_resume target methods.
Add simple to_wait and to_resume target methods that prevent stepping when the current replay position is not at the end of the execution log. 2014-01-16 Markus Metzger <markus.t.metzger@intel.com> * record-btrace.c (record_btrace_resume): New. (record_btrace_wait): New. (init_record_btrace_ops): Initialize to_wait and to_resume.
