Subject: [Qemu-devel] [RFC PATCH 03/21] linux-user: add -dfilter progtext shortcut
Date: Fri, 5 Oct 2018 16:48:52 +0100 [thread overview]
Message-ID: <20181005154910.3099-4-alex.bennee@linaro.org> (raw)
In-Reply-To: <20181005154910.3099-1-alex.bennee@linaro.org>
When debugging you often don't care about the libraries but just the
code in the testcase. Rather than make the user build this by hand
offer a shortcut.
