Subject: [PATCH v3 08/19] target/arm: Add semihosting stub to allow building without TCG
Date: Mon, 16 Mar 2020 17:06:23 +0100 [thread overview]
Message-ID: <20200316160634.3386-9-philmd@redhat.com> (raw)
In-Reply-To: <20200316160634.3386-1-philmd@redhat.com>
Semihosting requires TCG. When configured with --disable-tcg, the
build fails because the 'do_arm_semihosting' is missing. Instead
of adding more few more #ifdeffery to the helper code, add a stub.
