Subject: [PATCH v7 26/27] tcg/tci: Use {set,clear}_helper_retaddr
Date: Tue,  1 Jun 2021 08:01:05 -0700	[thread overview]
Message-ID: <20210601150106.12761-27-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210601150106.12761-1-richard.henderson@linaro.org>

Wrap guest memory operations for tci like we do for cpu_ld*_data.

We cannot actually use the cpu_ldst.h interface without duplicating
the memory trace operations performed within, which will already
have been expanded into the tcg opcode stream.

Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
