Re: [Qemu-devel] Please help build qemu/darwin-user on Mac Intel

2007-02-03 Thread Ilya Shar

Hi Mike, 

Thanks a lot for the patches.  I applied them
(together with qemu-0.7.0-gcc4.patch, which appears to
be necessary although it's not in the archive you
created) but in the middle of the build dyngen rejects
op.o: 

../dyngen -c -o opc.h op.o
dyngen: Unable to replace ret with jmp in
op_bsfl_T0_cc
make[1]: *** [opc.h] Error 1

Did I mess up somewhere or there is something wrong
with the patches?  

Thanks again for your help! 
Ilya

Hi,

we have decided to wait for the next qemu release until we update the  
patches for kju, as qemu dev has picked up speed, which is good.

Never the less, you can grab the patches for qemu cvs (OS X Intel) here:

Ilya, qemu's CVS has the most up-to-date version of darwin-user  
now, so you should use it intead of the version which is in the  
darwine's cvs. Moreover to compile qemu on intel you'll need a few  
patche. The team behind Q.app has collected them for you [1]. Also  
I am not sure that gcc 3.3 can build Mac Intel binaries that are  
compliant with the current Mac OS X x86 ABI. So you may also need  
the gcc 4.0 patches that you should find in [1].

Re: [Qemu-devel] Re: strange crash on FreeBSD-current/amd64 (pointer truncation?)

2007-02-03 Thread Gwenole Beauchesne


Hi,


Hmm.  All I can say is the upper half of rbx (which holds T0) gets
spilled on FreeBSD-current/amd64 hosts unless saving and restoring
the full 64 bit of it...


That's also what I got with VirtualBox on x86_64. Here is an update to  
the patch I posted yesterday and that applies to current QEMU CVS  
instead.


Please note this one applies unconditionnally of the host and target  
combinations. Besides, I only tested the following combinations:  
x86_64/x86_64-softmmu, x86_64/i386-softmmu, i586/x86_64-softmmu,  
i586/i386-softmmu. And I verified that the generated code for  
cpu_exec() with both gcc 3.4 and gcc 4.1 actually does the host  
registers save/restore correctly.


BTW, for e.g. SPARC hosts with %l registers, we could define  
something like DONT_PRESERVE_AREG since those would lay in a new  
register window and thus don't require an explicit save/restore.


Regards,
Gwenole Beauchesne

 Did anyone try the latest CVS qemu on Cygwin ?


AFAICT this is due to SDL. I did not succeed in compiling any SDL related 
stuff in cygwin, but then, I did not really try, since the MinGW 
compilation is easy enough.


I've successfully compiled SDL 1.2.11 on the fresh-installed Cygwin 1.5.24.
The following test SDL application works:
http://www.cse.nd.edu/courses/cse20211/www/code/sdl.html

The SDL/test contains a bunch of SDL testing applications.
Most of them works too, even sound- and OpenGL related.
