z80a: make mnemonic names more uniform across assemblers Initially, I used the same letters as those used in the z80 ref docs, but it makes the different assemblers harder to use than they should. Having consistent "argtype" rules across assemblers should help. 2020-06-27 22:01:56 -04:00			`A 0b11111101 LDri, ( TH output, unselected )`
