So the first step is to define an interface for getting at "extra"
registers such as Altivec and SSE - a PT_GETOTHERREGS would probably
work, but will lose as soon as we get Altivec2 registers or something
- and then do a little back-end glue in the PowerPC process_machdep.c
to recognize it.
couldn't we use the "int data" param of ptrace(2) to allow the new
PT_[GS]ETOTHERREGS to have an additional argument? that would allow
fairly extensive expansion :-)
