Make DO..LOOP stable DO and LOOP now only compile words from stable ABI, which make them suitable for xcomp. This will greatly simplify driver writing and allow us to mostly avoid the low/high divide in drivers. LEAVE is still xcomp-incompatible though. This make us very very tight for "<0x100" limit for literal words. Hopefully, we won't need more stuff in that area of the binary... 2020-05-12 10:37:24 -04:00			`CODE (br) ( 0x53 )`

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			`DE ADDIYd,`
