[Qemu-devel] qemu-1.0-rc1 delayed (need fix for PPC32 build)

[Anthony Liguori <aliguori@us.ibm.com>]

Hi,

I was hoping we'd have a solution by now but it looks like we don't.  I'm going 
to delay the qemu-1.0-rc1 release until tomorrow.  I'd like to propose a couple 
paths forward.  Here's my understanding of the situation:

1) TCG changes were made for the Sparc/Alpha targets that use AREG0

2) AREG0 never worked properly on ppc32 hosts

3) Until recently, this caused a runtime failure of the Sparc/Alpha targets on 
ppc32.  However, malc recently changed this to a build time failure.

I don't feel comfortable shipping a release candidate with a known failing 
build.  Here are the options:

a) Revert malc's change.  I don't think this is much better than shipping a 
broken build.

b) Disable sparc/alpha targets in default_target_list on ppc32 hosts.  I think 
is probably the best short term approach.

c) Wait for Andreas' patches (I believe Alex detected a problem in the current 
version).

Unless anyone strongly objects, I'm going to implement (b) tomorrow morning so 
we can keep the -rc cycle moving.  I would hope that we'll have something worked 
out for (c) by -rc2.

Regards,

Anthony Liguori
