[Qemu-devel] LLVM builds on Lion (Xcode 4.2.1)?

[Rui Carmo]

Hello, 

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.

Regards,

R.
