Hi,

I get these warnings when compiling i386 targets on Sparc host using a
gcc 4.3 series compiler:
/src/qemu/target-i386/ops_sse.h: In function 'helper_pmovmskb_mmx':
/src/qemu/target-i386/ops_sse.h:982: warning: array subscript is above
array bounds
etc.

The first line is the following:
   val |= (s->XMM_B(0) >> 7);

All the lines before #if SHIFT == 1 should be MMX_B really.

Scratch that. It should be this instead:

Acked-By: <address@hidden>

Care to commit the patch?

Fabrice was CCed, but i haven't heard his opinion.
