I see the changes - thanks! I'll start examining how to implement the
different approaches, starting with adding dssall for Altivec CPUs. 

One question I have: in the MPC7450 User's Manual, it states that a
"context switching" instruction must be given after the mtmsr
MSR[PSL_EE] instruction. Would you be able to elaborate or clarify this
statement, as I'm not real clear on what this means.

thanks, and I appreciate your working on a suggestion of mine.
