Cross compilation program
|
||||
|
||||
This programs allows cross compilation of boot binary and
|
||||
icore. Run "262 LOAD" right before your cross compilation and
|
||||
then set XCURRENT to CURRENT and XCOFF to H@.
|
||||
|
||||
This redefines defining words to achieve cross compilation.
|
||||
The goal is two-fold:
|
||||
|
||||
1. Add an offset to all word references in definitions.
|
||||
2. Don't shadow important words we need right now.
|
||||
|
||||
Words overrides like ":", "IMMEDIATE" and "CODE" are not
|
||||
automatically shadowed to allow the harmless inclusion of
|
||||
this unit. This shadowing has to take place in your xcomp
|
||||
configuration. (cont.)

Why limit ourselves to icore? Oh, I've tried cross-compiling

the whole shebang. I tried. And failed. Too dynamic.

The "X:" word
|
||||
|
||||
Because the ";" word goes back only one level in RSP and
|
||||
this limits our ability to separate X: in sub words and this
|
||||
means a rather cramped B265. This means no inline comments,
|
||||
hence this block here.
|
||||
|
||||
0x0e is compiledWord. first _find is on xdict. If found, we
|
||||
compile it with offsets. We abort on IMMED? because we're
|
||||
never supposed to encounter an immediate at this point.
|
||||
|
||||
If not found, we try the same word on system dict (RAM+02).
|
||||
If found and is immediate, execute. If founf and not immediate,
|
||||
error. If not found, try number.
