Subject: [RFC PATCH v2 19/19] target/arm: don't access TCG code when debugging with KVM
Date: Mon,  9 Jan 2023 19:42:32 -0300	[thread overview]
Message-ID: <20230109224232.11661-20-farosas@suse.de> (raw)
In-Reply-To: <20230109224232.11661-1-farosas@suse.de>

When TCG is disabled this part of the code should not be reachable, so
wrap it with an ifdef for now.

This allows us to start using CONFIG_TCG=n (--disable-tcg in the
configure line).
