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 hosts3) 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.
