z80: move boot code around Bring native words together, make the next/exec/does/compiled cluster be at the beginning. Next step: bring find code into _find word. 2020-07-05 22:23:40 -04:00			`lblexec @ JP,`

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			`C 0 IX+ LDrIXY,`

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 DECd, IX DECd,`
