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 :).
