[PATCH v4 22/48] accel/tcg: Add cpu_{ld,st}*_mmu interfaces

Posted by Richard Henderson 1 month, 2 weeks ago
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.
