Make word routines into word types Instead of having wordref point to core word routines, I made them into word 4 word types. It liberates space into the stable ABI and should make porting to other arches easier. I'm also thinking of combining word type with the namelen field for precious bytes saving, but not now... 2020-06-18 11:41:01 +10:00			`(xentry) 1 ( compiled ) C,`
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			`BEGIN`
De-stabilize EXIT This marks the end of wordrefs in stable ABI. Nice. 2020-09-20 10:35:35 +10:00			`WORD DUP LIT" ;" S= IF`

xcomp: add XCOMPILE and X[COMPILE] This allows us to move words like ABORT" to xcomp-core, which is I think the last roadblock before being able to unify all drivers into a single xcomp layer. 2020-05-13 11:08:18 +10:00			`_xapply ,`
