[Qemu-devel] Please help fix an illegal instruction / SSE problem

[Ilya Shar]

Every Cocoa application I try to run under
i386-darwin-user/qemu-i386 exits on an illegal
instruction: 

Starting
/Applications/Calculator.app/Contents/MacOS/Calculator
with qemu
----------------
queue_signal: sig=4
qemu: uncaught target signal 4 (Illegal instruction) -
exiting

The last block always executes SSE instructions: 
----------------
IN: 
0xffff0ab7:  movdqa 0xfffffffa(%esi,%edx,1),%xmm0
0xffff0abd:  movdqa 0xa(%esi,%edx,1),%xmm1
0xffff0ac3:  movdqa 0x1a(%esi,%edx,1),%xmm2
0xffff0ac9:  movdqa 0x2a(%esi,%edx,1),%xmm3
0xffff0acf:  movdqa 0x3a(%esi,%edx,1),%xmm4
0xffff0ad5:  movdqa %xmm0,%xmm5
0xffff0ad9:  movdqa %xmm4,%xmm0
0xffff0add:  data16
0xffff0ade:  (bad)  

Non-graphics applications run fine.  

Could it be a configuration/compilation problem
(although some SEE instructions seem to be handled
fine)?  If not, is there a way to better diagnose the
problem?  I on Mac OS Intel with QEMU 0.9.0. 

Thank you for your help! 
Ilya
