This is the cut down version of the earlier series omitting unfinished
patches that I plan to rework later and rebased to Mark's qemu-macppc
branch. Compared to v7 the only change is the cast to (target_ulong)
from (uint32_t) as requested by Mark in patch 1.
FWIW the reason for suggesting the cast to target_ulong is so that the same
code works for both qemu-system-ppc and qemu-system-ppc64. For
qemu-system-ppc that should correctly drop the sign extension from 32-bit,
whilst still allowing someone to load a 64-bit ELF into qemu-system-ppc64 if
requested.
Can you confirm that the sign extension behaviour is still correct for both
qemu-system-ppc and qemu-system-ppc64? If so I'm happy to give it a R-B tag.
I've tried it now again with both ppc and ppc64: both OpenBIOS and a G3
beige ROM can be loaded with qemu-system-ppc but qemu-system-ppc64 fails
with OpenBIOS when casting to target_ulong (i think because target_ulong
is 64 bit there but g3beige is still 32 bit but I haven't throughly
debugged it). But everything works with my original uint32_t cast, so
ditch it and use my original version. Should I resubmit or you can fix up?
(I think I wait until it's clear if this will be taken by David or you and
send a fixed version cc-ing David if this is decided to go through the PPC
queue.)
