Subject: [PATCH v5 41/43] tcg: Remove TCG_TARGET_SUPPORT_MIRROR
Date: Tue,  5 Jan 2021 07:19:48 -1000	[thread overview]
Message-ID: <20210105171950.415486-42-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210105171950.415486-1-richard.henderson@linaro.org>

Now that all native tcg hosts support splitwx, remove the define.
Replace the one use with a test for CONFIG_TCG_INTERPRETER.
