XPACKed core
|
||||
|
||||
Most of Collapse OS' core words are cross compiled (B390).
|
||||
However, some of them are too dynamically referenced to be
|
||||
cross-compiled without great pain, so we XPACK (B267) them,
|
||||
that is, we put them in source form in the target's
|
||||
initialization section (see B89).
|
||||
|
||||
These words will be compiled into RAM at initialization, which
|
||||
is a bit wasteful both in RAM and in boot time, so we will
|
||||
typically relink (B120) that newly compiled binary and append
|
||||
it to our existing binary for optimal resource usage.
|
||||
|
||||
Load range: 440-446

Ah, voice at last! Some lines above need comments

BTW: Forth lines limited to 64 cols because of default

input buffer size in Collapse OS
|

40 is ASCII for '('. We do this to simplify XPACK's task of
|

not mistakenly consider '(' definition as a comment.

COMPILE: Tough one. Get addr of caller word (example above

(br)) and then call LITA on it. )
