I miss the assembly. It was so clear and logical, like great engineering should always be. You could browse through it and comprehend at a glance what was happening. By contrast x86 assembly looks like pure rubbish, with stuff that most of the time looks like clever hacks coming from a bad night's sleep, like subtracting a register from itself to get zero... c'mon!
I hate to disappoint you, but the canonical way to clear a 68K address register is `SUBA.L An,An`. My asm-coded replacement for the Metrowerks code resource runtime uses it:
Oops, you're right. I forgot stuff like `MOVE.L #0,Dn` is restricted to data registers. So this must be the way to go, every time a NULL pointer is needed...
