Subject: [PATCH 4/5] sandbox: support Address and UndefinedBehavior sanitizers
Date: Thu, 22 Aug 2019 08:19:40 +0200	[thread overview]
Message-ID: <20190822061941.6093-5-ahmad@a3f.at> (raw)
In-Reply-To: <20190822061941.6093-1-ahmad@a3f.at>

For the hosted implementation, we just need to pass the appropriate
options at compile and link time. No further arch-specific
code needed.
