Subject: [PATCH v3 03/29] trace: Remove trace_mem_build_info_no_se_[bl]e
Date: Sun, 29 Dec 2019 10:10:58 +1100	[thread overview]
Message-ID: <20191228231124.18307-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20191228231124.18307-1-richard.henderson@linaro.org>

It is easy for the atomic helpers to use trace_mem_build_info
directly, without resorting to symbol pasting.  For this usage,
we cannot use trace_mem_get_info, because the MemOp does not
support 16-byte accesses.
