[Qemu-devel] [PATCH v2 0/18] tcg/arm: cleanup and improvements

[Aurelien Jarno]

This patch series clean-up and improves the tcg/arm code. The first
patches are just a clean-up and should not change the resulting 
binaries, while the other ones use new ARM instructions, and fix 
64-bit and/or big-endian targets.

With this patch series I am able to successfully:
- boot debian-installer on qemu-system-mips/mipsel
- run libc.so on qemu-i386, qemu-mips, qemu-mipsel, qemu-ppc,
  qemu-ppc64, qemu-sh4, qemu-x86_64

With this patch series I am able to partially:
- boot debian-installer on qemu-system-i386 and qemu-system-x86_64,
  but ld.so segfaults while coming to userland.
- boot the kernel on qemu-ppc. It deadlocks in the middle of the
  kernel boot. Strangely openbios crashes in initialize-forth on
  some machines (Feroceon 88FR131), but not on some others (Cortex-A9,
  qemu-system-arm emulating a versatilepb board).

With this patch series I am not able to:
- run libc.so on qemu-alpha. ld.so works though.

I have verified that all the problem above are not regressions (when
possible, as without this series, it is not possible to emulate a big
endian CPU).
