Subject: [PATCH v2 11/17] Use software single step to step out of a fast tracepoint jump pad
Date: Thu, 09 Jun 2016 12:56:00 -0000	[thread overview]
Message-ID: <1465476975-25062-12-git-send-email-antoine.tremblay@ericsson.com> (raw)
In-Reply-To: <1465476975-25062-1-git-send-email-antoine.tremblay@ericsson.com>

This patch enables software single step to be used to single step a thread
out of the fast tracepoint jump pad.

gdb/gdbserver/ChangeLog:

	* linux-low.c (linux_resume_one_lwp_throw): Use software single
	step if available to step out of the fast tracepoint jump pad.
