[Qemu-ppc] [PATCH for-1.1 0/3] tcg/ppc: AREG0 support and Darwin fixes

[Andreas Färber]

Hello malc,

This series fixes two long-standing issues on Darwin/ppc and, based on your
second patch, fixes the AREG0 mode for Linux and Darwin and thus the ppc build.

Compared to your last patch I have tried to avoid the { int ir; } block, and
I've combined both modes in one code path using ir and a new macro to handle
the alignment differences in a more explicit way.

Tested on Linux and Darwin, using i386 and x86_64 (non-AREG0) as well as sparc
and sparc64 (AREG0). On Darwin I observed a reproducible hang in fsck during
INIT under Debian/sparc, which given the lateness and now unified code paths
(i.e., Haiku/i386 and HelenOS/sparc64 working) I'd attribute to lingering
main loop / signal handling issues.

Regards,
Andreas
