Subject: [PATCH v10 16/28] frame, cfa: check unwind stop reason first
Date: Tue, 14 Jan 2014 08:05:00 -0000 [thread overview]
Message-ID: <1389686678-9039-17-git-send-email-markus.t.metzger@intel.com> (raw)
In-Reply-To: <1389686678-9039-1-git-send-email-markus.t.metzger@intel.com>
Swap the unwind stop reason check and the unwinder check to allow
non-dwarf2 frame types to fail with a recoverable error.
gdb/
2013-02-11 Jan Kratochvil <jan.kratochvil@redhat.com>
* dwarf2-frame.c (dwarf2_frame_cfa): Move UNWIND_UNAVAILABLE check
earlier.
