Virgil Dupras	3ea221d0eb	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
Virgil Dupras	b626944273	z80: move back R* words to native words section ... This allows us to refer to pushRS/popRS routines by labels, allowing us to get rid of the pushRS reference in the stable ABI zone.	2020-07-05 08:15:50 -04:00
Virgil Dupras	1094ec9c57	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 10:40:59 -04:00
Virgil Dupras	f54b1dc504	Add 2>R and 2R> ... This allows us to make DO..LOOP more compact.	2020-05-06 09:55:05 -04:00
Virgil Dupras	295b4b6e0a	z80a: add BIN( parameter ... Will be useful for assembling binaries for the TRS-80 which can't start at addr 0.	2020-04-27 15:11:38 -04:00
