Hi Jimi,

I guess we could do that. It's a bit strange your assembler is
complaining about the dcbtst instructions since we wrap them with
power4:
.machine push
.machine "power4"
dcbt r0,r4,0b01000
dcbt r0,r7,0b01010
dcbtst r0,r9,0b01000
dcbtst r0,r10,0b01010
eieio
dcbt r0,r8,0b01010 /* GO */
.machine pop
