[PATCH v2 00/17] record btrace: non-stop and ASNS

Changes to v1:
  - reworked non-stop test
  - changed the error string when trying to store registers while replaying
  - fixed all-stop/non-stop confusion in comments

This patch series adds support for non-stop mode to the record btrace target
and prepares for all-stop on top of non-stop (ASNS).

It adds a new scheduler-locking mode "reverse" for the current record btrace
behaviour of scheduler-locking during reverse/replay execution.

I tested this with the current all-stop and with Pedro's ASNS (by reverting
his disable patch).

The patch series can also be found on branch users/mmetzger/btrace-non-stop.

Markus Metzger (17):
  btrace: fix non-stop check in to_wait
  btrace: support to_stop
  btrace: improve stepping debugging
  btrace: extract the breakpoint check from record_btrace_step_thread
  btrace: split record_btrace_step_thread
  btrace: move breakpoint checking into stepping functions
  btrace: add missing NO_HISTORY
  btrace: lock-step
  btrace: resume all requested threads
  btrace: temporarily set inferior_ptid in record_btrace_start_replaying
  btrace: async
  infrun: switch to NO_HISTORY thread
  btrace: non-stop
  target, record: add PTID argument to to_record_is_replaying
  btrace: allow full memory and register access for non-replaying
  target: add to_record_stop_replaying target method
  infrun: scheduler-locking reverse
