[PATCH v3 0/5] thread, btrace: allow "record btrace" for running threads

[Markus Metzger <markus dot t dot metzger at intel dot com>]

This refers to:  https://sourceware.org/ml/gdb-patches/2016-11/msg00994.html.

The first version tried to detect the error in gdbserver, propagate it back, and
handle it in btrace.

Versions 2 and 3 check whether registers can be accessed before making the request
to gdbserver based on feedback from Pedro.

Version 3 addresses Pedro's feedback and adds more patches to address test suite
issues that were identified during reviews.

Markus Metzger (5):
  thread: add can_access_registers_ptid
  btrace: allow recording to be started (and stopped) for running
    threads
  btrace: add unsupported/untested messages when skipping tests
  btrace, testsuite: fix extended-remote non-stop test
  btrace, testsuite: fix extended-remote fail
