gdb, btrace: make record-btrace per-inferior
When there is more than one inferior, the "record btrace" command should only apply to the current inferior. gdb/ChangeLog: 2020-03-19 Markus Metzger <markus.t.metzger@intel.com> * record-btrace.c (record_btrace_enable_warn): Ignore thread if its inferior is not recorded by us. (record_btrace_target_open): Replace call to all_non_exited_threads () with call to current_inferior ()->non_exited_threads (). (record_btrace_target::stop_recording): Likewise. (record_btrace_target::close): Likewise. (record_btrace_target::wait): Likewise. (record_btrace_target::record_stop_replaying): Likewise. gdb/testsuite/ChangeLog: 2020-03-19 Markus Metzger <markus.t.metzger@intel.com> * gdb.btrace/multi-inferior.c: New test. * gdb.btrace/multi-inferior.exp: New file.
