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 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.

Virgil Dupras 80d730318a Simplify LOAD's INTERPRET exit mechanism 2020-05-13 22:55:52 -04:00
Virgil Dupras 2e9e7047bf Make INTERPRET break on ASCII EOT 
This should allow me to simplify LOAD's exit mechanism on block
end.

Virgil Dupras 052d59a3a2 TOWORD: tiny optimization 
My mind is getting forthy.
 2020-05-13 20:59:00 -04:00
Virgil Dupras 33d37d4ce9 WORD: don't overwrite RAM on words over 31 chars 
This allows me to reclaim some RAM I hadn't even noticed I
needlessly monopolise.
 2020-05-13 20:39:53 -04:00
Virgil Dupras 76037ca1e7 Simplify boot process 
That INIT thing is unnecessary.
 2020-05-13 14:19:54 -04:00
Virgil Dupras bb77cd0759 xcomp: add overrides into a loadable block 
Makes xcomp.fs units shorter.

Virgil Dupras 0434d02818 xcomp: implement X['] 2020-05-13 13:24:58 -04:00
Virgil Dupras 7c20501f27 Move core's blk to xcomp core (low and high) 
TODO: implement X['] so that I can remove those XCURRENT patterns.

Virgil Dupras ddf23e3d02 Move a bunch of words from core to xcomp core 2020-05-13 07:55:36 -04:00
Virgil Dupras cbf5baf3b6 Pack core words a bit 
This leaves space for xcomp-core which is growing.
 2020-05-12 21:27:06 -04:00
Virgil Dupras dfe474ca0e 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.
 2020-05-12 21:08:18 -04:00
Virgil Dupras 1094ec9c57 Make DO..LOOP stable 
DO and LOOP now only compile words from stable ABI, which make them
suitable for xcomp. This will greatly simplify driver writing and
allow us to mostly avoid the low/high divide in drivers.

LEAVE is still xcomp-incompatible though.

This make us very very tight for "<0x100" limit for literal words.
Hopefully, we won't need more stuff in that area of the binary...
 2020-05-12 10:40:59 -04:00
Virgil Dupras b760c2d353 SCPY: don't copy the NULL 
This makes [entry] much simpler. Also, remove unused LITS word.
 2020-05-12 07:36:20 -04:00
Virgil Dupras 231d727598 Move a few words from core to xcomp core 2020-05-12 07:21:34 -04:00
Virgil Dupras da371451cc Replace INITIAL_SP with PS_ADDR conf 
Now I struggle to remember why I ever did things they way I did.
There must have been a reason...

Virgil Dupras 4ce0727c72 ti84: kbd driver wip 2020-05-09 11:55:58 -04:00
Virgil Dupras afc2327770 Split icore in 2 parts 
The goal is to insert device drivers in between.
 2020-05-08 21:47:03 -04:00
Virgil Dupras baf725aa38 Move a bunch of words from core to inner core 
That makes it easier to write drivers that can be xcompiled.
 2020-05-08 20:55:50 -04:00
Virgil Dupras b90efb0f7f ti84: first glyph on screen! 
On the emulator of course...
 2020-05-08 09:07:44 -04:00
Virgil Dupras 58ec54fc97 ti84: wip 
Gave more priority to CPU in the emulator because initialization would
otherwise be horrendously slow.
 2020-05-08 07:56:34 -04:00
Virgil Dupras 24e588019b Add words RSHIFT and LSHIFT 2020-05-07 15:41:43 -04:00
Virgil Dupras eaeb138a0c Add words C@- C!- and MOVE- 2020-05-06 20:37:08 -04:00
Virgil Dupras 58ece9f9a1 editor: implement I command 
Also, made LIST properly handle full 64-chars lines not ending with
a null or CR. Previously, such a line would be accompanied by its
following line, duplicating that line's output.
 2020-05-06 12:19:36 -04:00
Virgil Dupras f54b1dc504 Add 2>R and 2R> 
This allows us to make DO..LOOP more compact.
 2020-05-06 09:55:05 -04:00
Virgil Dupras 60b4bbf28a Fix DUMP's broken "round up to next 8" logic 
This was caused by the removal of signed-ness a long while ago.
 2020-05-05 22:09:11 -04:00
Virgil Dupras 31119c2de3 xcomp: move all offset spitting to the end of the unit 
I'd like to move this code, along with all recipe contents, to blk/.
It's easier if "emul-related" code is gathered at the same place.
 2020-05-05 20:10:04 -04:00
Virgil Dupras fa79e3d8a6 Make (print) stop on CR 
Lines edited with the Block editor end with 0xd and (print) spits
spurious CR when printing those lines.

Also, properly initialize ACC in BROWSE.
