Subject[2.6.30-rc8 KVM] gcc 3.3 dies at emulate_2op_cl().
From

(Continued from http://lkml.org/lkml/2009/6/4/14 )
I tried to identify the location of gcc 3.3's internal error using
"make CONFIG_DEBUG_INFO=1 arch/x86/kvm/x86_emulate.s", and it turned out that
the location is emulate_2op_cl().

Commenting out like below solves the gcc's internal error.

I think something is wrong with emulate_2op_cl() when compiled with gcc 3.3.5 .

Regards.
