Virgil Dupras ebf47a2ab5 Fix broken LIT" 2020-07-05 20:50:08 -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.

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.

Virgil Dupras 94cb76520a Refer to stable wordref by direct offset in "hot zone" immediates 
Previously, it was impossible to cross-compile Collapse OS from a
binary-offsetted Collapse OS because stable ABI wordrefs would have
a wrongly offsetted address.

This solves the problem by replacing those wordrefs by direct,
hardcoded stable ABI offset references.

Virgil Dupras 3068b58be5 Rename RAMSTART to SYSVARS 
It's more descriptive this way. Also, I'll soon add a new HERESTART
config.

Virgil Dupras 36cb1389e6 Add a C implementation of native words 
This will soon replace the libz80 based "forth" and
"stage" executables. This is much, much faster.
