Could you do the same thing on ia32, using
Register::kMaxNumAllocatableRegisters?
Thanks Michael, Why I don't do the same thing on ia32 is that in my memory,
ia32
will keep some value in xmm0 when calling into runtime. So ia32 may
intentionally save all its 8 XMMRegsiters. An example is like the
xmm_scratch in
DoDeferredNumberTagI.
