Remove LIT< in favor of LIT" exclusively This duplicated feature existed because of bootstrapping issues with LIT", but again, with careful threading, we can clean things up. We can now have a proper "Collapse OS" prompt :) 2020-09-20 08:51:29 +10:00			`( We don't use ." and ABORT in core, they're not xcomp-ed )`

Move Cross-compiled core from B390 to B350 and renamed it "Core words". Also, reworded the presentation. 2020-05-16 12:44:49 +10:00			`: BEGIN H@ ; IMMEDIATE`
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... 2020-09-20 03:54:01 +10:00			`: AGAIN COMPILE (br) H@ - _bchk C, ; IMMEDIATE`

Remove LITA It was useful when we still had the relinker, but now it has no use. I was waiting a bit to see if the distinction would be useful again, but it seems like it won't. 2020-06-18 03:50:42 +10:00			`: COMPILE ' LITN ['] , , ; IMMEDIATE`

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. 2020-07-05 21:09:11 +10:00			`: ['] ' LITN ; IMMEDIATE`
Remove ";" word The ":" now takes care of scanning for ";". Conceptually, having ";" as an immediate word is slightly simpler than the approach in this commit, but when bootstrapping is involved, this simpler approach gets murkier. Moreover, it got even murkier-er when trying to de-stabilize EXIT, so here we are. 2020-09-20 10:19:23 +10:00			`':' X' _ 4 - C! ( give : its name )`
