[Qemu-devel] [PATCH 0/4] ARM aarch64 TCG target VERSION 2

[Claudio Fontana <claudio.fontana@huawei.com>]

This series implements preliminary support for the ARM aarch64 TCG target.

Limitations of this initial implementation (TODOs) include:

 * missing TLB lookup in qemu_ld/st [C helpers always called].
   An incremental patch, which requires this series, is coming up
   from teammate Jani Kokkonen to implement this.
 * most optional opcodes are not implemented yet (only rotation done).
 * CONFIG_SOFTMMU only
 * only little endian qemu targets supported

Tested running on a x86-64 physical machine running Foundation v8,
running a linux 3.8.0-rc6+ minimal host system based on linaro v8
image 201301271620 for user space.

Tested guests: arm v5 test image, i386 FreeDOS test image,
i386 linux test image, all from qemu-devel testing page.
Also tested on x86-64/linux built with buildroot,
and on arm v7/linux built with buildroot as well.

checkpatch emits a false positive for the last patch regarding
missing braces which are actually there. I suspect it is
because of a comment.

checkpatch also complains about the labeled statements in
the switch, which I think are in fact good for readability.

Claudio Fontana (4):
  include/elf.h: add aarch64 ELF machine and relocs
  tcg/aarch64: implement new TCG target for aarch64
  configure: permit compilation on arm aarch64
  tcg/aarch64: implement more low level ops in preparation of tlb lookup
