I posted this to the list a couple of days ago but I still don't see it in the archives, so here goes again...

I've been trying to get a working build of QEMU 1.0 (or HEAD) that would build or run on Mac OS X Lion without segfaulting or spinlocking, and so far the only way I've been able to build it _and_ run it is by using gcc-4.2 instead of LLVM. Clang doesn't work either (it doesn't support global register variables).

I was wondering who might be looking into that, since I couldn't figure out where this kind of issue would be classified in the MAINTAINERS file I've only found Andreas (hi!) listed where it concerns Cocoa, but this is not a Cocoa issue.

For the record, the way I got it to build was patching fpu/softfloat.h (see below, I think this has been submitted as a formal patch by someone else, but can't find it either) and setting --cc=gcc-4.2 --host-cc=gcc-4.2.

The issue with that is that "plain" GCC isn't bundled with Xcode anymore (even though I have it on all the machines I tried this, it was apparently removed around Xcode 4.1 or thereabouts and my upgrades preserved it), so I'd like to get in touch with someone that might be able to address the LLVM issue.





(remember, this is not a formal patch)
