Subject: [PATCH v4 2/8] target/m68k: Add semihosting stub
Date: Wed, 17 Jul 2024 12:57:17 +0200	[thread overview]
Message-ID: <20240717105723.58965-3-philmd@linaro.org> (raw)
In-Reply-To: <20240717105723.58965-1-philmd@linaro.org>

Since the SEMIHOSTING feature is optional, we need
a stub to link when it is disabled.

Suggested-by: Paolo Bonzini <pbonzini@redhat.com>
Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
