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			`0 A,, ( prev )`

Make word routines into word types Instead of having wordref point to core word routines, I made them into word 4 word types. It liberates space into the stable ABI and should make porting to other arches easier. I'm also thinking of combining word type with the namelen field for precious bytes saving, but not now... 2020-06-17 21:41:01 -04:00			`0 A, ( native )`
z80a: add BIN( parameter Will be useful for assembling binaries for the TRS-80 which can't start at addr 0. 2020-04-27 15:04:37 -04:00			`0x14 BCALL, ( popRS )`
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 PUSH, IY POP, ( --> IP )`
