z80: inline all uses of pushRS/popRS I'm trying to move stuff around and it simplifies things. Will make a lot more sense to inline when BC replaces IY. 2020-07-05 21:54:01 -04:00			`IX INCd, IX INCd,`
z80: Use BC as IP register instead of IY It's a bit more inconvenient in terms of register protection (BC is much more generally useful than IY), but it makes tight spots such as next and execute much faster, so I think it's worth it. 2020-07-06 23:31:00 -04:00			`0 IX+ C LDIXYr,`
			`1 IX+ B LDIXYr,`

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			`HL INCd,`
