Hi,
I would like to debug a Qemu guest linux kernel under Foundationv8 model
and I tried the following setup:
1. Foundationv8 model started with --network=nat and
--network-nat-ports=1234=1234 options
2. In Foundationv8 model I started qemu-system-aarch64 with the command
line:
./qemu-system-a

Tested guests: arm v5, PPC64, sparc, i386 linux test images.
Also tested on x86-64/linux built with buildroot.

implement the optional byte swap operations with the dedicated
aarch64 instructions.
These instructions are also needed for the tlb lookup.

From: Jani Kokkonen
This series implements the TCG tlb fast lookup in tcg_out_qemu_ld/st
for the aarch64 TCG target.
It requires the reviewed but not committed yet series
"[PATCH v4 0/3] ARM aarch64 TCG target" at:
http://lists.nongnu.org/archive/html/qemu-devel/2013-05/msg04200.
From: Claudio Fontana
for arith operations, add SUBS and add a shift parameter
so that all arith instructions can make use of shifted registers.
Also add functions to TEST/AND registers with immediate patterns.
