From 14776ab5a12972ea439c7fb2203a4c15a09094b4 Mon Sep 17 00:00:00 2001 From: Tony Nguyen Date: Sat, 24 Aug 2019 04:10:58 +1000 Subject: tcg: TCGMemOp is now accelerator independent MemOp Preparation for collapsing the two byte swaps, adjust_endianness and handle_bswap, along the I/O path. Target dependant attributes are conditionalized upon NEED_CPU_H.
