Subject: [PATCH v2 34/55] accel/tcg: Add cpu_{ld,st}*_mmu interfaces
Date: Mon, 2 Aug 2021 18:14:22 -1000 [thread overview]
Message-ID: <20210803041443.55452-35-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210803041443.55452-1-richard.henderson@linaro.org>
These functions are much closer to the softmmu helper
functions, in that they take the complete MemOpIdx,
and from that they may enforce required alignment.
The previous cpu_ldst.h functions did not have alignment info,
and so did not enforce it. Retain this by adding MO_UNALN to
the MemOp that we create in calling the new functions.
