Virgil Dupras	eefbf66e95	De-stabilize (br), (?br), (loop), (s) ... When writing the xcomp documentation, I realized that with careful threading and by accepting a bit of code duplication in the xcomp toolset, I could de-stabilize a couple of words. (n) and EXIT are a bit trickier, but I think it can be done. It would be nice to get rid of stable wordrefs...	2020-09-19 13:54:01 -04:00
Virgil Dupras	c4db9d4420	8086: implement stack overflow error condition ... Also, remove RSP underflow check from next for the same reason as in the previous commit in z80.	2020-08-08 10:18:43 -04:00
Virgil Dupras	f2f520cacc	Extract (br), (?br) and (loop)'s code out of stable ABI zone ... There is now no more actual code in stable ABI, only references. This makes refactoring of this code much easier. For example, changing IY to BC as the IP register.	2020-07-05 14:57:18 -04:00

Virgil Dupras	4a91ee5c9c	Extract (s) code from stable ABI zone ... Only its jump addr remains.	2020-07-05 08:54:22 -04:00
Virgil Dupras	650481f849	z80/8086: extract 2>R code from stable ABI zone ... Only its jump at 0x33 remains. I've also fixed a strange offset oddity in 8086's (n) placement. It was off by 2, but strangely, it ran properly. Anyway, now it's fixed.	2020-07-05 08:03:15 -04:00
