Subject: [PATCH v4 01/12] accel/tcg: Add stub for cpu_loop_exit()
Date: Wed, 30 Sep 2020 00:43:44 +0200	[thread overview]
Message-ID: <20200929224355.1224017-2-philmd@redhat.com> (raw)
In-Reply-To: <20200929224355.1224017-1-philmd@redhat.com>

Since the support of SYS_READC in commit 8de702cb67 the
semihosting code is strongly depedent of the TCG accelerator
via a call to cpu_loop_exit().

Ideally we would only build semihosting support when TCG
is available, but unfortunately this is not trivial because
semihosting is used by many targets in different configurations.
For now add a simple stub to avoid link failure when building
with --disable-tcg:

  hw/semihosting/console.c:160: undefined reference to `cpu_loop_exit'
