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.
