[Qemu-devel] [Bug 1239385] [NEW] qemu reboot when execute some SSE instruction

[Zhou Yi Chao]

Public bug reported:

I'm using qemu-system-i386 on a x86-64 platform doing my OS homework.

When qemu execute

c0102f9a:       66 0f 6e 45 a0          movd   -0x60(%ebp),%xmm0
c0102f9f:       66 0f d6 45 d0          movq   %xmm0,-0x30(%ebp)

My virtual OS reboots.  Maybe the following old patch is useful
:

I'm using qemu-1.5.3.
