[PATCH v2 0/4] gdb, btrace: infrun fixes

[Markus Metzger]

Changes in v2:
  - address feedback from Pedro Alves

There's still an open question raised here:
https://sourceware.org/pipermail/gdb-patches/2021-November/183700.html.

    I'm wondering if prepare_one_step() should reset tp->control.step_stop
    to zero.  It does re-initialize tp->control.step_range_start/end and
    we do start another step.


Markus Metzger (4):
  gdb, infrun, btrace: fix reverse/replay stepping at end of execution
    history
  gdb, infrun, record: fix hang when step-over fails with no-history
  gdb, infrun, record: move no-history notification into normal_stop
  gdb, infrun: fix multi-threaded reverse stepping
