Subject: [PATCH  v2 1/5] target/arm: remove unused EXCP_SEMIHOST leg
Date: Fri, 20 Dec 2019 13:22:42 +0000	[thread overview]
Message-ID: <20191220132246.6759-2-alex.bennee@linaro.org> (raw)
In-Reply-To: <20191220132246.6759-1-alex.bennee@linaro.org>

All semihosting exceptions are dealt with earlier in the common code
so we should never get here.
