Or inc/dec...

Uh - huh? How would that help?

inc shared->critical   # disable interrupts

There is no opcode in the ppc isa that acts on momery without  
involving a register.

An inc would be:

ld rX, A(0)
addi rX, rX, 1
std rX, A(0)

Right, I was agreeing with you.  I meant there was no inc/dec mem  
insns.

Ah, I see :). I think that's really the only point where I deem the  
x86 isa superior :).
