Virgil Dupras cdddfdefae avra: add a layer of indirection to FLBL! 
This will make it easier to fit BR* in there.

Virgil Dupras 63dec372ce sms/kbd: continue advancing on ps2ctl rewrite 
Still binary matching. Next step is branching support.

Virgil Dupras 177e70580f sms/kbd: begin rewriting ps2ctl to Forth 
So far, the resulting binary matches.

Virgil Dupras 0f2d14ad8a z80a: add BREAK, instruction 
This allows us to remove a lot of labels usage in boot code. This
commit has no effect on forth.bin.

and renamed it "Core words". Also, reworded the presentation.

Virgil Dupras 1597f1e131 Don't generalize XYPOS just yet 
It was ill-advised.

Virgil Dupras db9885b8cf Rename (find) to FIND 
I hadn't noticed that this word was almost ANS compliant.

Virgil Dupras 175b4bc497 sms: CollapseOS prompt! 2020-05-15 12:46:25 -04:00
Virgil Dupras ca60685067 Streamline initialization process 
Instead of letting each configuration taking care of RDLN$ and
"CollapseOS" prompt, move this to BOOT to simplify xcomp units.

Initialization source code is now only for driver initialization.

Virgil Dupras 0163af470a Fix EOT behavior after QUIT 
Previously, calling quit would break EOT behavior and not properly
quit Collapse OS.

Virgil Dupras faa2576f83 CI: don't needlessly run tests twice 
Verifying that forth.bin is stable is enough. Also, fix shebang.

Virgil Dupras 87b51a6261 By default, allocate about 0x100 bytes for PSP+RSP 
During "make updatebootstrap", we use less than 0x20 bytes on the
PSP side and less than 0x40 bytes on the RSP one. 0x100 bytes ought
to be enough for anybody.

Virgil Dupras bf289b0a67 z80a: de-variable-ize 
Use straight VARIABLE instead of Z80MEM+. Initially, I used this
system to allow z80a to be embedded in a system binary, but now
I don't think it's worth it. Compiled, z80a is 2.5k. Sure, it's a
sizeable amount of RAM, but I think that even with it in RAM, I'll
manage a bootstrap within my most constrained machine, the SMS with
8K.

Virgil Dupras 3fbae082f4 Remove INTJUMP mechanism 
Not worth the trouble. Easier to set jump in binary directly.

Virgil Dupras e6bac985fa Cross-compiles in a single stage! 
Finally got rid of the XPACKed core and managed to cross-compile
all core words, which greatly simplifies the bootstrapping process.

Virgil Dupras 74896051bb Move BOOT, (boot<) and INTEPRET to high xcomp 
Saves us an (ok) indirection and will save us more soon.
