 		 #88898 - MOV bit,bit
Responding to: ???'s previous message
Bartosz Wucke said:
That one is missing seriously :) Stupid hardly ever used features like DA, XCHD, several dozens of opcodes wasted on ACALL/AJMP, and there's no bit comparison instruction.


A "MOV bit,bit" opcode would have been extremely useful. I would have actually preferred that to either ANL C,/bit or ORL C,/bit.

But now we are getting into the land of dreaming. Can't modify the instruction set and really call it an 8051 anymore.
